Early Preview: Unified MCP Tool Graph – Feedback, Testing, and Collaboration Welcome

[pratikjadhav2726]

Hi everyone,

I’ve opened up the first version of the Unified MCP Tool Graph –
a project aimed at solving a major bottleneck in agentic systems:
how to dynamically retrieve and select the right tools across thousands of APIs and MCP servers — without hardcoding or manual setup.

Right now, the project includes:
• A Neo4j-powered tool graph with vector search
• Dynamic retrieval based on semantic matching of tool descriptions
• Retrieval optimized for available user credentials (you only get tools you can actually use)
• A FastMCP server ready for LangChain / LangGraph agent integration

⸻

🎯 What works today:
• Load tools from multiple MCP servers
• Embed tool descriptions locally
• Query the graph with task descriptions
• Return a minimal set of relevant tools for any task
• Run a FastMCP retrieval server on top of the graph

⸻

📋 Areas still under active development:
• Improving retrieval scoring and fallback strategies
• Adding relationships like overlaps_with, preferred_for_task
• Extending to larger multi-domain toolsets
• Streamlining deployment for production use
• Cleaner client interfaces and LangChain templates

⸻

🚀 I’d love your help with:
• Testing retrieval with different types of tasks and agents
• Finding edge cases or ideas for smarter retrieval
• Suggestions for better metadata organization or graph expansion
• Collaboration on scaling this beyond a prototype
