Jitapi

Point Claude at any API. JitAPI figures out which endpoints to call and in what order — automatically. Register any OpenAPI spec, search endpoints in plain English, and orchestrate multi-step workflows across multiple APIs. No API keys required — works out of the box with local e
Overview
What is Jitapi?
Jitapi is an MCP server that lets Claude interact with any API from its OpenAPI spec, using semantic search and a dependency graph to surface only the needed endpoints.
How to use Jitapi?
Install via pip (pip install jitapi) and add the server configuration to your MCP client with command: "uvx" and args: ["jitapi"]. Then register any OpenAPI spec URL, search endpoints in plain English, and Claude chains the right API calls automatically.
Key features of Jitapi
- Zero-config: no API keys required for local embeddings
- Multi-API orchestration: register and query across multiple APIs
- Automatic dependency graph resolution for endpoint chains
- Semantic search in natural language instead of exact paths
- Pluggable embeddings: local, Voyage AI, OpenAI, or Cohere
Use cases of Jitapi
- Querying any REST API (e.g., Stripe, GitHub) via Claude without loading the full spec
- Building cross-API workflows that automatically resolve endpoint dependencies
- Rapid prototyping of integrations without writing a custom MCP server per API
FAQ from Jitapi
How does Jitapi handle large API specs?
It uses semantic search and a dependency graph to surface only what’s needed, avoiding context token waste and hallucinations.
What runtime dependencies does Jitapi require?
Python with pip; it runs via uvx. Local embeddings work out of the box without external API keys.
Can I use my own embedding model?
Yes. Jitapi supports pluggable embeddings: local (default), Voyage AI, OpenAI, or Cohere.
How are endpoint dependencies resolved?
Jitapi builds a dependency graph that knows which endpoints must be called first (e.g., GET /users before POST /orders) and resolves this automatically.
Does Jitapi support multiple APIs simultaneously?
Yes. You can register multiple OpenAPI specs and ask questions that span them.
