Corsair
Open-source integration layer for AI agents — OAuth, MCP, webhooks done right
About Corsair
Corsair is an open-source integration layer for AI agents and apps: secure multi-tenant OAuth, permission management, MCP support, webhooks, credential handling, caching and provider-specific error handling for Gmail, Slack, Notion, HubSpot, Airtable, Google Calendar, Stripe, Linear, GitHub and Discord — the services your users actually expect agents to touch.\n\nThe pitch is "add any integration in minutes" and the numbers back the credibility: 11.3k GitHub stars, self-host the SDK for free or use their managed cloud so you never maintain token rotation, webhook verification, API change tracking or rate-limit handling yourself. Anyone who has built OAuth flows for more than two providers knows exactly how much unpaid plumbing that is.\n\nWho it's for: developers shipping AI agents or assistant products who want integrations as infrastructure instead of a permanent side project. Bring your own execution (hosted or self-hosted instances) and keep tenant credentials isolated. If your roadmap has "add Slack integration" penciled in for the third sprint in a row, this buys that time back — just review the self-host docs before committing your credential storage architecture to it.

What to consider before using Corsair
Corsair is one of many tools in its category. Before committing to it, weigh a few practical points that tend to decide whether a tool actually fits your work:
- Match the tool to your real task, not to its feature count. A tool that excels at your specific job beats one with a longer checklist you will never use.
- Check how it fits your existing workflow — integrations, export formats, and whether the output needs heavy manual cleanup.
- Read the license and pricing terms for commercial use, especially if you plan to publish or resell what the tool produces.
