Jitapi
Solves the problem of working with massive OpenAPI specs by using semantic search and dependency graphs instead of dumping hundreds of endpoints into context. Register any API once (Stripe, GitHub, TMDB), ask questions in plain English, and it figures out which endpoints to call and in what order. The dependency resolver is the standout piece: it knows that creating an order requires getting a user ID first, so it chains the calls automatically. Works offline with local embeddings out of the box, or you can plug in Voyage/OpenAI for better search quality on large APIs. Supports bearer tokens, API keys, and basic auth through environment variables so credentials never hit disk. Best for multi-step workflows across unfamiliar APIs where you'd otherwise be reading docs or writing custom integration code.

Readme
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.
