Smart Routing is MCPHub’s intelligent tool discovery system that uses vector semantic search to automatically find the most relevant tools for any given task.

HTTP Endpoint

  • Endpoint: http://localhost:3000/mcp/$smart
  • Method: POST

SSE Endpoint (Deprecated)

How it Works

  1. Tool Indexing: All MCP tools are automatically converted to vector embeddings and stored in PostgreSQL with pgvector.
  2. Semantic Search: User queries are converted to vectors and matched against tool embeddings using cosine similarity.
  3. Intelligent Filtering: Dynamic thresholds ensure relevant results without noise.
  4. Precise Execution: Found tools can be directly executed with proper parameter validation.

​
Setup Requirements

  • PostgreSQL with pgvector extension
  • LLM Provider (OpenAI or compatible) API key
  • Enable Smart Routing in MCPHub settings
