Google Calendar integration for AI agents.

Google Calendar integration for AI agents with secure authentication and server-side credential injection. Open Connector runs the OAuth, seals the token in an encrypted vault, and serves Google Calendar tools to your agent over MCP or a typed API — credentials injected server-side, every call audited, nothing leaving your infrastructure. Open source (AGPL-3.0) and self-hostable.

What your agents can do

Real Google Calendar actions, managed and audited.

Your user connects Google Calendar once; your agent can then secure AI-agent actions — scoped to the OAuth permissions you grant and the tool allowlist you configure. Every action is least-privilege and written to a tamper-evident audit trail.

  1. 1

    Your user grants Google Calendar access once (OAuth) — the token lands in the vault.

  2. 2

    Your agent calls a tool over MCP or the typed API; Open Connector injects the credential server-side.

  3. 3

    Every routed call appends a hash-chained audit record — nothing leaves your infra.

FAQ

Google Calendar integration, answered

How do AI agents use Google Calendar through Open Connector?
Your user connects Google Calendar once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes Google Calendar tools to your agent over MCP or a typed API, with credentials injected server-side on each call.
Is this a Google Calendar MCP server?
Yes. Open Connector can serve Google Calendar as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call Google Calendar actions with credentials injected server-side.
Where do Google Calendar credentials live?
In your own infrastructure. Open Connector keeps credentials in its own vault and injects them at call time, so they never leave your environment.
