Corsair -Open Source Integration Layer

Open source integration layer for secure, agent-driven app access.

About

Corsair is an open source integration layer for AI agents, built natively on the Model Context Protocol (MCP). It connects any API to any AI model through pre built connectors, a hosted Hub, and a typed TypeScript SDK you can self host for free. Corsair handles the parts of integration work that quietly become a maintenance burden: OAuth and token refresh, multi tenant credential isolation, webhook signature verification, API deprecations, and rate limit handling. None of your credentials or user data are stored on Corsair's side; the hosted Hub acts purely as a relay between your product and each integration. Built in permissions mean destructive actions require explicit approval before they execute, so your users get a review link instead of a surprise. Backed by Y Combinator and licensed Apache 2.0, Corsair is fully open source:
