# Agents, API & MCP

OpenEmail is meant to be operated by software as well as by people. The mailbox is the same either way.

## In this section

- [MCP server](https://openemail.uk/docs/knowledge/agents/mcp.md): Point Claude, or any MCP client, at your mailbox.
- [OAuth for third-party clients](https://openemail.uk/docs/knowledge/agents/oauth.md): Self-service client registration with PKCE, so an app can ask for access properly.
- [REST API](https://openemail.uk/docs/knowledge/agents/api.md): A documented HTTP API with issuable, scopable, revocable keys.
- [Typed SDKs](https://openemail.uk/docs/knowledge/agents/sdk.md): A TypeScript client first, then the rest.
- [Webhooks](https://openemail.uk/docs/knowledge/agents/webhooks.md): Tell your endpoint when mail arrives, instead of making you poll.
