Saved weeks of OAuth plumbing for our agent stack.
MCP support out of the box is huge.
Clean SDK and solid docs.
Self-hosting setup takes some tinkering.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Per-user OAuth flows, consent screens, secure credential isolation, and token rotation so one product can safely serve many customers' accounts.
Prebuilt connectors for Gmail, Slack, Notion, HubSpot, Airtable, Google Calendar, GitHub, Linear, Stripe, and hundreds more, reachable from a single SDK.
Run the integration runtime on Corsair's managed cloud or inside your own infrastructure with the open-source SDK, including a TypeScript SDK.
Model Context Protocol support and a personal MCP address via lug.dev, so agents in Claude, ChatGPT, Cursor, and other MCP clients can use connected apps.
Human approval gates before risky actions, API caching, rate-limit handling, and webhook synchronization to keep agent runs stable under production load.
Corsair targets a specific and painful problem: every AI agent that acts on a user's behalf needs to reach the apps that user already lives in. Doing that well means OAuth flows per tenant, safe credential storage, token rotation, granular permissions, rate limits, retries, and webhook plumbing — infrastructure that has nothing to do with the agent's actual intelligence but consumes enormous engineering time. Corsair packages that layer so teams can add integrations in minutes instead of maintaining them for years.
The platform exposes a TypeScript SDK alongside a hosted cloud option, so a product can run the integration runtime itself or let Corsair operate it. Agents interact through structured tool calls against connected apps, with approvals gating risky actions. Corsair also ships an MCP-oriented path, including its lug.dev offering, which lets users claim a personal MCP address and connect apps once so tools like Claude, ChatGPT, Cursor, and other MCP clients can use them.
Corsair is open source with a large GitHub following and a commercial cloud tier. Coverage spans Gmail, Slack, Notion, HubSpot, Google Calendar, GitHub, Linear, Stripe, Airtable, PostHog, Discord, and many more, making it a practical foundation for anyone building an agent that needs to actually do work inside real SaaS tools rather than just talk about it.
Add Gmail, Slack, or HubSpot connections to an agent in minutes while Corsair handles consent, tokens, scopes, and refresh logic across every tenant.
Let an agent search Apollo for prospects, skip contacts already in HubSpot, draft Gmail outreach, and post results to Slack, with approval before anything risky.
Read Zendesk tickets, group duplicates, file Linear issues with ticket links, and post a summary to Slack without custom glue code for each tool.
Deploy the open-source SDK behind your own security boundary to keep customer tokens isolated while still giving agents broad app reach.
