Corsair provides an open-source integration layer that lets AI agents connect to SaaS applications and databases without building and maintaining custom API connections. The platform offers prebuilt connectors, permission controls, and self-hosting options, enabling teams to ship production-grade integrations while avoiding vendor lock-in and reducing infrastructure costs.

Problem
Building and maintaining integrations between AI agents and external SaaS applications is time-consuming and fragile. APIs change frequently, auth flows rotate, and error handling varies per provider, causing connections to break quietly over time. Closed-source integration tools limit teams to whatever connectors the vendor has built, leaving them blocked when they need something unsupported.
Solution
Corsair takes the integration layer off the plate by providing production-grade, open-source connectors that package authentication, endpoints, and data mapping for specific SaaS applications. The platform supports Model Context Protocol (MCP) servers, enabling agents to discover and call tools across many applications through a standardized interface. Teams can self-host the full SDK on their own infrastructure at no cost, with no per-seat pricing or vendor markup on API calls. Permission modes per integration protect users by requiring explicit approval for destructive actions, and the open-source nature means teams can fork the repo or submit pull requests to add exactly the integrations they need.
Target Audience
Primary customers are engineering teams building AI agents or AI-powered products that need to connect to external SaaS applications and databases, particularly those who want to avoid vendor lock-in and maintain control over their integration infrastructure.
Features
- Prebuilt connectors for common SaaS applications that handle authentication, data normalization, and error recovery out of the box
- MCP server support standardizing how agents discover and invoke tools across multiple applications
- Permission modes per integration that require explicit approval for destructive actions, with review links for end users
- Self-hosted deployment option with no per-seat pricing, no data leaving the stack, and no vendor markup on API calls
- Open-source codebase that teams can fork or contribute to via pull requests, eliminating vendor lock-in
- Database tools for internal data and API tools for external services, with support for both direct function calling and MCP-based connections
- Scoped access controls and approval gates to mitigate security risks from overly broad read access or unverified writes
