Microsoft integration for AI agents.
Microsoft 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 Microsoft 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.
Real Microsoft actions, managed and audited.
Your user connects Microsoft 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
Your user grants Microsoft access once (OAuth) — the token lands in the vault.
- 2
Your agent calls a tool over MCP or the typed API; Open Connector injects the credential server-side.
- 3
Every routed call appends a hash-chained audit record — nothing leaves your infra.
Microsoft tool surface.
The following managed tool groups are exposed by this integration. Each item is surfaced as tool metadata so agents can discover safe actions and build reliable workflows.
- Microsoft tools
- Secure AI-agent actions.
Microsoft integration, answered
- How do AI agents use Microsoft through Open Connector?
- Your user connects Microsoft once with one of its cataloged authentication methods. Open Connector stores the credential in an encrypted vault and exposes Microsoft tools to your agent over MCP or a typed API, with credentials injected server-side on each call.
- Is this a Microsoft MCP server?
- Yes. Open Connector can serve Microsoft as a named MCP server with a scoped allowlist and a per-user connection URL, so any MCP client can call Microsoft actions with credentials injected server-side.
- Where do Microsoft 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.
Give your agents Microsoft — keep the keys.
