Quick answers
What is corsair?
An open-source integration platform offering a unified REST API for AI agents and customer dashboards to connect with third-party apps.
What does corsair do?
Corsair provides a standardized integration layer that allows developers to connect their applications to numerous third-party tools using a single, consistent syntax. Unlike platforms limited solely to the Model Context Protocol (MCP), Corsair exposes a REST API, making its integrations accessible to both AI agents and traditional backend services or multi-tenant user dashboards. It abstracts away the complex glue code and adapter maintenance required for different APIs. Being open-source, it allows developers to self-host the infrastructure, ensuring that sensitive user tokens and integration data remain fully under their control.
Who is corsair for?
Software developers and engineering teams building products that require extensive integrations with third-party APIs. It is particularly useful for those building AI agents or SaaS platforms who want to avoid writing and maintaining custom API glue code.

Unified syntax: Provides a single, consistent API structure for interacting with various disparate third-party services.
REST API architecture: Enables integrations to be consumed by AI agents, backend services, and front-end user dashboards.
Open-source core: Allows developers to inspect the integration logic and self-host the platform to maintain data sovereignty.
Managed OAuth: Offers a hosted Hub option to handle the complexities of OAuth token refreshes and webhook delivery.
Maintained adapters: Centralizes the maintenance of third-party API connections so developers don't have to rewrite plumbing.
Multi-tenant support: Built to handle integrations for multiple distinct users or organizations within a single deployment.
Where teams use it
AI agent integration
Equipping an AI agent with the ability to perform actions across multiple external tools using a single API interface.
Customer dashboards
Building a settings page where users can authenticate and connect their own third-party accounts to your application.
Data synchronization
Standardizing the process of pulling data from various external platforms into an internal database.
Self-hosted infrastructure
Deploying an integration layer on private servers to ensure user tokens are never exposed to a third-party managed service.
Getting started: Visit the documentation at https://corsair.dev to configure your first integration.
Corsair is a fully-featured product integration platform with a seamless DX. Build anything, from an agent working across all your integrations to a multi-tenant dashboard for your users to connect to anything.
Why does this exist?
More than MCP
Most agent integration tools are MCP-only. Corsair is built on a REST API, so the same integration layer works for agents, backend services, and the dashboards your customers use.
One syntax for every integration
The more third-party APIs your agent touches, the more glue code you write. Corsair gives every integration the same syntax, and we maintain the adapters behind it. Connect once instead of rewriting plumbing for each new tool.
Open source, your data
Closed integration platforms keep your users' tokens and data on infrastructure you can't inspect or leave. Corsair is open source. Self-host it, or use Hub if you want us to handle OAuth refresh and webhooks. Your data remains yours either way.
