JitAPI
Point Claude at any API. JitAPI figures out which endpoints to call and in what order — automatically.
JitAPI is an MCP server that lets Claude interact with any API from its OpenAPI spec. Instead of dumping hundreds of endpoints into context, JitAPI uses semantic search and a dependency graph to surface only what's needed — then Claude plans and executes the calls.

The Problem
Stripe has 300+ endpoints. GitHub has 800+. Loading the full spec into Claude's context wastes tokens and causes hallucinations. Writing a custom MCP server for every API you use doesn't scale.
JitAPI solves this: register any OpenAPI spec once, then ask for what you need in plain English. It finds the right endpoints, resolves dependencies between them, and lets Claude execute the calls.
Quick Start
pip install jitapiAdd to your Claude Code config (.mcp.json):
{
"mcpServers": {
"jitapi": {
"command": "uvx",
"args": ["jitapi"]
}
}
}
