Agents are increasingly capable of performing real work across many services—but handing them raw API keys or unrestricted access creates real operational and security risk. Corsair addresses that gap by centralizing authentication, token refresh, data sync, and approval gating so the agent only ever observes method names and results while sensitive secrets remain encrypted and under your control.
What Sets It Apart
- Per-tenant, envelope encryption model: you supply a KEK (key-encrypting key) that encrypts per-tenant data keys; those keys encrypt the actual service tokens. So credentials live in your database and remain unreadable to agents.
- Permission-first execution: integrations expose permission modes (open, cautious, strict, readonly) and per-endpoint overrides. Destructive or sensitive actions can require explicit human approval before executing.
- Plugin + single API surface: hundreds of integrations are provided as typed plugins with a consistent SDK surface, typed webhook handlers, and a small, fixed schema (four tables) regardless of how many integrations you add—reducing schema bloat and integration maintenance.
- Hub as an optional relay: if you prefer not to host OAuth/connect/approval surfaces, the Hub can relay those UIs while still keeping tokens encrypted in your DB—Corsair Hub does not store your credentials.
Who It's For and Trade-offs
Great fit if you run or build AI agents that must interact with multiple third-party services in production, especially in multi-tenant scenarios where isolated credentials, scoped permissions, and approval workflows are required. It suits engineering teams that want a consistent integration layer (typed plugin clients, webhook handling, polling/webhook sync) and are willing to host a small service plus a database and manage an encryption key.
Look elsewhere if you need a minimal client-only wrapper with no hosting, if you prefer to manage every vendor SDK and token lifecycle yourself, or if you cannot accept the operational cost of running a service and key management. Also, you may need to write or extend plugins for niche integrations not yet covered.
Corsair’s design trades a bit of operational overhead (hosting, DB, KEK management) for stronger runtime guarantees: agents cannot exfiltrate keys, permission requests are recorded in an agent-inaccessible database row, and integrations share uniform tooling for approvals, rate-limiting, and data caching.
