Maximizing Your Claude Max Subscription: Complete Guide to Automated Workflows with Claude Code and Windsurf

Publié le 27 mai 2025 par loic

The Claude Max plan at $100 per month has revolutionized how developers can integrate Claude’s powerful AI capabilities directly into their development workflow. With the recent integration of Claude Code into the Max subscription, users can now access terminal-based AI assistance without burning through expensive API tokens. This comprehensive guide shows you how to set up a complete development environment using Windsurf, Claude Code, and your Claude Max subscription, including advanced automation workflows that maximize productivity.

Understanding the Claude Max Plan Value Proposition

The $100 monthly Claude Max plan provides 5x more usage than Claude Pro, translating to approximately 225 messages every 5 hours. This expanded capacity makes it ideal for developers who need sustained AI assistance throughout their coding sessions without constantly hitting usage limits.

What makes this plan particularly attractive is the inclusion of Claude Code at no additional cost. Previously, using Claude Code required separate API tokens, but as of May 2025, Max plan subscribers can use Claude Code directly through their subscription.

Setting Up Claude Code with Your Max Subscription

Installation and Authentication

Getting started with Claude Code on your Max plan is straightforward. First, install Claude Code following the official documentation, then authenticate using only your Max plan credentials.

The key is ensuring you’re using your Max subscription rather than API credits:claude logout claude login

During the login process, authenticate with the same credentials you use for claude.ai and decline any API credit options when prompted. This ensures Claude Code draws exclusively from your Max plan allocation.

Avoiding API Credit Prompts

One crucial aspect of staying within your $100 monthly budget is preventing Claude Code from defaulting to API credits when you approach your usage limits. Configure your setup to avoid these prompts entirely by:

Using only Max plan credentials during authentication
Declining API credit options when they appear
Monitoring your usage with the /status command

Integrating Claude Code with Windsurf via MCP

Windsurf’s Model Context Protocol (MCP) support allows you to create a seamless bridge between Claude Code and your IDE. This integration transforms Claude Code into an MCP server that Windsurf can call upon for complex coding tasks.

MCP Configuration

Create or modify your mcp_config.json file in Windsurf’s configuration directory:

macOS: ~/.codeium/windsurf/mcp_config.json
Windows: %APPDATA%\Codeium\windsurf\mcp_config.json
Linux: ~/.config/.codeium/windsurf/mcp_config.json

Add this configuration:{ "mcpServers": { "claude-code": { "command": "claude", "args": ["mcp", "serve"], "env": {} } } }

Starting the MCP Server

Launch Claude Code as an MCP server directly from your terminal:claude mcp serve

This command transforms Claude Code into a service that Windsurf can interact with programmatically, providing access to Claude’s coding capabilities through the MCP protocol.

Creating Custom Workflows for Automatic Task Delegation

With Claude Code accessible via MCP, you can create sophisticated custom workflows that automatically delegate specific types of tasks to Claude Code. This automation maximizes your productivity while staying within your Max plan limits.

During development sprints: « I’m currently working toward [goal]. Does this align with what I truly value, or am I chasing the wrong thing? »

8. The Fear Dissector

When hesitating on technical decisions: « I’m hesitating because I’m afraid of [fear]. Is this fear rational? What’s the worst that could realistically happen? »

9. The Feedback Forager

For fresh perspective: « Here’s what I’ve been thinking: . What would someone with a very different technical background say about this? »

10. The Tradeoff Tracker

For architectural decisions: « I’m choosing between [option A] and [option B]. What are the hidden costs and benefits of each that I might not be seeing? »

11. The Progress Checker

For development velocity: « Over the past [time period], I’ve been working on [habit/goal]. Based on my current actions, am I on track or just spinning my wheels? »

12. The Values Mirror

When feeling disconnected from work: « Lately, I’ve felt out of sync. What personal values might I be neglecting or compromising right now? »

13. The Time Capsule Test

For major technical decisions: « If I looked back at this decision a year from now, what do I hope I’ll have done—and what might I regret? »

Test-Driven Development (TDD) Rules

Write tests first before any production code.
Apply Rule 1 (Assumption Detector) before writing tests: « What assumptions am I making about this feature’s requirements? »
Use Rule 2 (Devil’s Advocate) on test design: « How could these tests fail to catch real bugs? »

The Future of Retrieval: A Fusion of ColBERT, LightRAG, and RAPTOR

Publié le 17 avril 2025 par loic

In the evolving landscape of information retrieval and AI-powered search, three innovative approaches have emerged as game-changers: ColBERT, LightRAG, and RAPTOR. Each brings unique strengths to the table, but their true potential lies in fusion—combining these technologies to create a retrieval system greater than the sum of its parts. Let’s explore these models and how their integration can revolutionize information retrieval.

ColBERT: Contextual Precision at the Token Level

ColBERT (Contextualized Late Interaction over BERT) represents a significant advancement in neural information retrieval. Unlike traditional retrieval methods that compress entire documents into single vectors, ColBERT preserves the contextual representation of each token in both queries and documents.

What makes ColBERT special is its « late interaction » mechanism. Rather than computing a single similarity score between query and document vectors, ColBERT calculates fine-grained interactions between each query token and document token. This approach allows for more precise matching, especially for queries containing specific terms or phrases.

The beauty of ColBERT lies in its ability to balance the precision of exact matching with the contextual understanding of neural models. When a user searches for specific technical terms or rare phrases, ColBERT can identify the exact matches while still understanding their context within documents.

LightRAG: Graph-Based Knowledge Navigation

LightRAG takes a fundamentally different approach by leveraging graph structures to represent knowledge. Think of it as creating a map of information where entities (like concepts, people, or objects) are connected through meaningful relationships.

The « Light » in LightRAG refers to its streamlined architecture compared to more complex graph-based retrieval systems. It focuses on three core elements: entities, relations, and the graph itself. This simplification makes it more efficient while maintaining powerful retrieval capabilities.

What sets LightRAG apart is its dual-level retrieval paradigm. When processing a query, it first identifies relevant entities and then navigates the connections between them. This allows the system to follow logical paths through information—much like how humans make connections between related concepts.

For example, if you’re researching climate change impacts on agriculture, LightRAG might connect entities like « rising temperatures, » « crop yields, » and « food security » even if they don’t appear together in the same document. This ability to bridge information gaps makes LightRAG particularly powerful for complex queries requiring multi-hop reasoning.

RAPTOR: Hierarchical Understanding Through Recursive Abstraction

RAPTOR (Recursive Abstractive Processing for Tree-Organized Retrieval) approaches information organization from yet another angle—hierarchical abstraction. It builds a tree-like structure of information at varying levels of detail, from specific facts to broad concepts.

The process begins by breaking documents into small chunks and embedding them using semantic models. These chunks are then clustered based on similarity, and a language model generates concise summaries for each cluster. This process repeats recursively, creating higher-level summaries until a comprehensive hierarchical structure emerges.

What makes RAPTOR powerful is its ability to maintain both breadth and depth of understanding. When responding to a query, it can navigate this tree structure to find the appropriate level of detail—providing broad context when needed or drilling down to specific facts.

This hierarchical approach is particularly valuable for complex topics where understanding requires both the big picture and specific details. For instance, when researching a medical condition, RAPTOR can provide both high-level overviews of treatment approaches and specific details about particular medications.

The Power of Fusion: Creating a Hybrid Retrieval System

While each of these approaches offers significant advantages, their true potential emerges when combined into a hybrid system. Here’s how these technologies complement each other:

Complementary Strengths

ColBERT excels at precise token-level matching, making it ideal for queries requiring exact phrase matching or specific terminology.

LightRAG shines in connecting related information across documents, enabling multi-hop reasoning and bridging knowledge gaps.

RAPTOR provides hierarchical context, allowing the system to understand both broad themes and specific details within a topic.

How Fusion Works

A fused retrieval system leverages all three approaches in parallel, then combines their results through a sophisticated ranking algorithm. Here’s a conceptual workflow:

Query Processing: When a user submits a query, it’s processed simultaneously by all three systems.
Multi-faceted Retrieval:

ColBERT identifies documents with precise token-level matches
LightRAG navigates entity relationships to find connected information
RAPTOR traverses its hierarchical structure to retrieve relevant summaries and details

Result Fusion: The results from each system are combined using a weighted fusion algorithm that considers:

The confidence score from each retrieval method
The diversity of information provided
The complementary nature of the retrieved content

Contextual Ranking: The final ranking considers not just relevance to the query, but also how pieces of information complement each other to provide a comprehensive answer.

Real-world Benefits

This fusion approach addresses the limitations of individual retrieval methods:

Improved Recall: By leveraging multiple retrieval strategies, the system captures relevant information that might be missed by any single approach.
Enhanced Precision: The combination of ColBERT’s token-level precision with the contextual understanding of RAPTOR and LightRAG’s relational awareness leads to more accurate results.
Contextual Depth: The system can provide both broad overviews and specific details, adapting to the user’s information needs.
Complex Query Handling: Multi-hop questions that require connecting information across documents become manageable through LightRAG’s graph traversal capabilities.

The Future of Retrieval

As we look ahead, this fusion of ColBERT, LightRAG, and RAPTOR represents the cutting edge of retrieval technology. The approach moves beyond simple keyword matching or even pure semantic search to create a more human-like understanding of information—one that recognizes precise details, understands relationships between concepts, and grasps both the forest and the trees.

For enterprises dealing with vast knowledge bases, research institutions navigating complex scientific literature, or content platforms seeking to enhance user experience, this hybrid approach offers a powerful solution that mimics human information processing while leveraging the speed and scale of modern computing.

The future of retrieval isn’t about choosing between these approaches—it’s about bringing them together in harmony to create systems that truly understand the complexity and interconnectedness of human knowledge.

Creating an MCP Server from Any FastAPI URL with One Prompt

Publié le 30 mars 2025 par loic

In the rapidly evolving landscape of AI-assisted development, the Model Context Protocol (MCP) has emerged as a game-changer. But what if you want to connect your AI assistants to existing FastAPI applications without modifying their code? Today, I’ll show you how to create an automatic MCP server from any FastAPI URL using just one prompt in Cursor.

The Power of FastAPI’s OpenAPI Documentation

FastAPI automatically generates comprehensive OpenAPI (formerly Swagger) documentation for all endpoints. This documentation contains everything needed to understand and interact with the API:

Endpoint paths and HTTP methods
Request parameters and body schemas
Response formats and status codes
Detailed descriptions and examples

This rich metadata is exactly what we need to create an MCP server that can proxy requests to the original API.

The One-Prompt Solution

Copy and paste this prompt into Cursor to generate a complete, ready-to-run MCP server that connects to any FastAPI application:

Create a complete Python script that generates an MCP server from the FastAPI application running at {URL}. The script should:

1. Fetch the OpenAPI/Swagger documentation from {URL}/openapi.json
2. Analyze all endpoints, parameters, request bodies, and response models
3. Create a new FastAPI application that:
   - Mirrors all the endpoints from the original API
   - Forwards requests to the original API
   - Returns responses from the original API
4. Add MCP server functionality using the fastapi_mcp library
5. Include proper error handling for:
   - Connection issues
   - Authentication failures
   - Invalid responses

The final script should be a single, self-contained Python file that:
- Takes command line arguments for customization (port, authentication, etc.)
- Includes detailed comments explaining how it works
- Can be run directly with "python script.py" to start the MCP server
- Automatically connects to {URL} and creates an MCP server at http://localhost:8000/mcp

Replace {URL} with the actual URL of the FastAPI application, for example https://api.example.com.

The output should be ONLY the complete Python script, ready to run, with no explanations before or after the code.

Automate MCP Integration in Your FastAPI App with a Single Copy/Paste

Publié le 30 mars 2025 par loic

Modern APIs need more than just endpoints—they require robust documentation, strong typing, and seamless integration with advanced AI assistants. In our fast-paced development environment, every minute counts. That’s why today we’re exploring how to leverage a single, well-crafted Cursor prompt to automatically refactor an existing FastAPI application and integrate the Model Context Protocol (MCP) with zero extra manual adjustments.

What Is MCP and Why Does It Matter?

MCP (Model Context Protocol) is a lightweight framework that enables AI assistants to interact with your APIs. By converting your API endpoints into well-documented, standardized MCP tools, AI models (like those running in Cursor or Claude 3.7 Sonnet) can automatically discover and call your API functions. This not only enhances interoperability but also allows for dynamic, natural-language-driven interactions with your app.

Why Improve Your FastAPI Code First?

Before unlocking the power of MCP, your API needs to be in top shape. This means:

Comprehensive docstrings for each endpoint.
Detailed type hints and Pydantic models for requests and responses.
Robust error handling with proper HTTP exceptions.
Clear descriptions for every route so that MCP can easily « discover » and interpret them.

By improving your code according to these best practices, you’re ensuring that the MCP integration can accurately reflect your API’s capabilities, leading to smarter, reliable interactions for AI assistants.

Automating Everything with a Cursor Prompt

Imagine being able to improve your code—and add a whole new MCP interface—to your FastAPI project by simply pasting one prompt into Cursor. No more manual tweaks or back-and-forth adjustments. The idea is to use a precise instruction that tells the AI exactly how to:

Refactor your existing code for better quality.
Automatically insert MCP integration using the fastapi_mcp library.
Generate the final, runnable code along with testing and configuration instructions.

Here’s why this approach is so powerful:

It removes the need for manual intervention.
It standardizes your API transformation process.
It sparks creativity by letting the AI fill in the boilerplate, making your API production-ready with minimal hassle.
It works with non-perfect AI systems by laying out each necessary step, ensuring no detail is lost.

The Final Cursor Prompt

Copy and paste the following prompt directly into Cursor. This instruction tells the AI to first improve your existing FastAPI code with best practices and then add the MCP route using the fastapi_mcp library—all in one go:

I have an existing FastAPI application that is functional but not optimized. Your job is to improve the code and integrate MCP (Model Context Protocol) using the fastapi_mcp library. Follow these steps carefully:

### Step 1: Improve the Existing FastAPI Code
1. **Docstrings**: Add detailed docstrings to all endpoints. Each docstring should include:
   - A brief description of what the endpoint does.
   - Parameters with their types and descriptions.
   - The response format, including success and error cases.
   - HTTP status codes used by the endpoint.
2. **Type Hints**: Ensure all functions have proper type hints for parameters and return values.
3. **Pydantic Models**:
   - Define Pydantic models for request bodies (if any).
   - Use Pydantic models for response validation (`response_model` in FastAPI).
4. **Error Handling**:
   - Use `HTTPException` with appropriate status codes for errors.
   - Handle edge cases gracefully with meaningful error messages.
5. **Endpoint Descriptions**: Add a `description` parameter to each route decorator to describe what the endpoint does.

### Step 2: Integrate MCP
1. Install the `fastapi_mcp` library:
   ```
   pip install fastapi_mcp
   ```
2. Import the necessary function:
   ```
   from fastapi_mcp import add_mcp_server
   ```
3. Add MCP functionality to the FastAPI app:
   - After initializing your `FastAPI` app, call `add_mcp_server()`.
   - Mount the MCP server at `/mcp`.
   - Use a descriptive name for your MCP server (e.g., "My API MCP").
4. Ensure that all existing endpoints remain functional after adding the MCP server.

### Step 3: Provide Testing Instructions
1. Generate a JSON configuration snippet to connect this MCP server in Cursor:
   ```
   {
     "mcpServers": {
       "My API MCP": {
         "url": "http://127.0.0.1:8000/mcp"
       }
     }
   }
   ```
2. Provide a sample `curl` command to test the `/mcp` endpoint:
   ```
   curl -X POST http://127.0.0.1:8000/mcp/tools
   ```

### Input Example
Here is an example of my current FastAPI code (simplified):
```
from fastapi import FastAPI, HTTPException

app = FastAPI()

@app.get("/items")
def get_items():
    return {"items": []}

@app.get("/items/{item_id}")
def get_item(item_id: int):
    if item_id == 0:
        raise HTTPException(status_code=404, detail="Item not found")
    return {"item_id": item_id}
```

### Output Requirements
- Refactor the above code to follow best practices (as outlined in Step 1).
- Add MCP integration (as described in Step 2).
- Provide a complete, runnable code block with comments explaining each change.
- Include testing instructions (as described in Step 3).

The final output should look like this:
1. The improved and MCP-integrated code.
2. A JSON snippet for connecting this API as an MCP server in Cursor.
3. A sample `curl` command to test the `/mcp` route.

DO NOT skip any steps or provide vague explanations—output only complete, ready-to-use code.

How This Works

By pasting the above prompt into Cursor, you delegate the entire transformation process to the AI assistant. It will:

Refactor your code to meet professional standards.
Automatically insert the MCP integration using fastapi_mcp.
Produce a self-contained code snippet with detailed comments and testing instructions.

This means you can convert an imperfect API into a fully MCP-compliant service without directly writing additional code!

Conclusion

This method not only accelerates your development process but also minimizes human error by standardizing integration tasks. With one thoughtfully constructed prompt, you can harness the power of AI to bring your FastAPI application up to production level—complete with modern documentation and remote AI assistant compatibility via the MCP protocol.

Try it out in your next project and experience a new level of automation that allows you to focus on what matters most: building innovative features while letting the AI take care of the boilerplate.

Enhancing Document Retrieval with Topic-Based Chunking and RAPTOR

Publié le 11 mars 2025 par loic

In the evolving landscape of information retrieval, combining topic-based chunking with hierarchical retrieval methods like RAPTOR represents a significant advancement for handling complex, multi-topic documents. This article explores how these techniques work together to create more effective document understanding and retrieval systems.

Topic-Based Chunking: Understanding Document Themes

Topic-based chunking segments text by identifying and grouping content related to specific topics, creating more semantically meaningful chunks than traditional fixed-size approaches. This method is particularly valuable for multi-topic documents where maintaining thematic coherence is essential.

The TopicNodeParser in LlamaIndex provides an implementation of this approach:

It analyzes documents to identify natural topic boundaries
It segments text based on semantic similarity rather than arbitrary token counts
It preserves the contextual relationships between related content

After processing documents with TopicNodeParser, you can extract the main topics from each node using an LLM. This creates a comprehensive topic map of your document collection, which serves as the foundation for more sophisticated retrieval.

RAPTOR: Hierarchical Retrieval for Complex Documents

RAPTOR (Recursive Abstractive Processing for Tree Organized Retrieval) builds on chunked documents by organizing information in a hierarchical tree structure through recursive clustering and summarization. This approach outperforms traditional retrieval methods by preserving document relationships and providing multiple levels of abstraction.

Choosing the Right RAPTOR Method

RAPTOR offers two primary retrieval methods, each with distinct advantages for different use cases:

Tree Traversal Retrieval navigates the hierarchical structure sequentially, starting from root nodes and moving down through relevant branches. This method is ideal for:

Getting comprehensive overviews of multiple documents
Understanding the big picture before exploring details
Queries requiring progressive exploration from general to specific information
Press reviews or reports where logical flow between concepts is important

Collapsed Tree Retrieval flattens the tree structure, evaluating all nodes simultaneously regardless of their position in the hierarchy. This method excels at:

Complex multi-topic queries requiring information from various levels
Situations needing both summary-level and detailed information simultaneously
Multiple recall scenarios where information is scattered across documents
Syndicate press reviews with multiple intersecting topics

Research has shown that the collapsed tree method consistently outperforms traditional top-k retrieval, achieving optimal results when searching for the top 20 nodes containing up to 2,000 tokens. For most multi-document scenarios with diverse topics, the collapsed tree approach is generally superior.

Creating Interactive Topic-Based Summaries

The final piece of an effective document retrieval system is interactive topic-based summarization, which allows users to explore document collections at varying levels of detail.

An interactive topic-based summary:

Presents topics hierarchically, showing their development throughout documents
Allows users to expand or collapse sections based on interest
Provides contextual placement of topics within the overall document structure
Uses visual cues like indentation, bullets, or font changes to indicate hierarchy

This approach transforms complex summarization results into comprehensible visual summaries that help users navigate large text collections more effectively.

Implementing a Complete Pipeline

A comprehensive implementation combines these techniques into a seamless pipeline:

Topic Identification: Use TopicNodeParser to segment documents into coherent topic-based chunks
Topic Extraction: Apply an LLM to identify and name the main topics in each chunk
Hierarchical Organization: Process these topic-based chunks with RAPTOR to create a multi-level representation
Retrieval Optimization: Select the appropriate RAPTOR method based on your specific use case
Interactive Summary: Create an interactive interface that allows users to explore topics at multiple levels of detail

This pipeline ensures that no topics are lost during processing while providing users with both high-level overviews and detailed information when needed.

Conclusion

The combination of topic-based chunking, RAPTOR’s hierarchical retrieval, and interactive summarization represents a powerful approach for handling complex, multi-topic document collections. By preserving the semantic structure of documents while enabling flexible retrieval at multiple levels of abstraction, these techniques significantly enhance our ability to extract meaningful information from large text collections.

As these technologies continue to evolve, we can expect even more sophisticated approaches to document understanding and retrieval that will further transform how we interact with textual information.

Evaluating Chunking Strategies for RAG: A Comprehensive Analysis

Publié le 26 janvier 2025 par loic

Text chunking plays a crucial role in Retrieval-Augmented Generation (RAG) applications, serving as a fundamental pre-processing step that divides documents into manageable units of information[1]. A recent technical report explores the impact of different chunking strategies on retrieval performance, offering valuable insights for AI practitioners.

Why Chunking Matters

While modern Large Language Models (LLMs) can handle extensive context windows, processing entire documents or text corpora is often inefficient and can distract the model[1]. The ideal scenario is to process only the relevant tokens for each query, making effective chunking strategies essential for optimal performance.

Key Findings

Traditional vs. New Approaches
The study evaluated several chunking methods, including popular ones like RecursiveCharacterTextSplitter and innovative approaches such as ClusterSemanticChunker and LLMChunker[1]. The research found that:

Smaller chunks (around 200 tokens) generally performed better than larger ones
Reducing chunk overlap improved efficiency scores
The default settings of some popular chunking strategies led to suboptimal performance[1]

Novel Chunking Methods
The researchers introduced two new chunking strategies:

ClusterSemanticChunker: Uses embedding models to create chunks based on semantic similarity
LLMChunker: Leverages language models directly for text chunking[1]

Evaluation Framework

The study introduced a comprehensive evaluation framework that measures:

Token-level precision and recall
Intersection over Union (IoU) for assessing retrieval efficiency
Performance across various document types and domains[1]

Practical Implications

For practitioners implementing RAG systems, the research suggests:

Default chunking settings may need optimization
Smaller chunk sizes often yield better results
Semantic-based chunking strategies show promise for improved performance[1]

Looking Forward

The study opens new avenues for research in chunking strategies and retrieval system optimization. The researchers have made their codebase available, encouraging further exploration and improvement of RAG systems[1].

For those interested in diving deeper into the technical details and implementation, you can find the complete research paper at Evaluating Chunking Strategies for Retrieval.
