About Corsair
Corsair is an open-source integration platform designed for AI agents to connect with third-party applications through secure, multi-tenant OAuth flows, webhooks, and MCP. It eliminates the need for developers to build or maintain underlying integration infrastructure by handling authentication, schema changes, and error handling automatically. The platform supports popular services such as Gmail, Slack, Notion, HubSpot, and GitHub, with built-in permission controls that require explicit user approval for destructive actions. Developers can choose to self-host the full SDK at no cost or opt for a managed cloud offering with tiered pricing. Corsair is specifically built for AI agent workflows, ensuring seamless connectivity and reducing the complexity of managing multiple integrations across providers. The platform simplifies the process of integrating AI agents with external tools, making it easier to deploy and scale agent-based applications without the overhead of custom integration development.
