Jitapi

What is JitAPI?

JitAPI is an MCP server that lets Claude interact with any API from its OpenAPI spec. Instead of dumping hundreds of endpoints into
context, it uses semantic search and a dependency graph to surface only what's needed.

The Problem

Stripe has 300+ endpoints. GitHub has 800+. Loading a full API spec into Claude's context wastes tokens and causes hallucinations. Writing a custom MCP server for every API doesn't scale.

How It Works

1. Register any OpenAPI spec URL
2. Search endpoints in plain English
3. Execute — Claude chains the right API calls automatically

JitAPI builds a dependency graph that knows "you need to call GET /users first to get the user_id for POST /orders" — and resolves this
automatically.

Key Features

• Zero-config: Works out of the box with local embeddings. No API keys required.
• Multi-API orchestration: Register multiple APIs, ask questions that span them
• Dependency graphs: Automatically resolves endpoint dependencies
• Semantic search: Find endpoints using natural language, not exact paths
• Pluggable embeddings: Local (default), Voyage AI, OpenAI, or Cohere

Quick Start

pip install jitapi

{                                                                                                                                          
  "mcpServers": {
    "jitapi": {                                                                                                                            
      "command": "uvx",                                   
      "args": ["jitapi"]
    }
  }
}
