# UCL MCP Gateway

> UCL is a hosted MCP gateway: aggregate any number of MCP servers and databases behind a single endpoint, add per-user OAuth (bring-your-own-account), governance (RBAC/ABAC, PHI/PII redaction, audit logging) and per-tool config, then connect Claude, Cursor, ChatGPT, or any AI agent.

## Get started
- [Quickstart: connect your MCP gateway](https://katana.orchestration.dev/docs/quickstart): Connect an MCP server, get your single gateway URL, and call your tools from Claude, Cursor, or any agent in under 5 minutes.

## Concepts
- [What is an MCP gateway?](https://katana.orchestration.dev/docs/what-is-an-mcp-gateway): An MCP gateway is a single endpoint that aggregates many MCP servers, adds auth, governance, and audit, and exposes one unified tool catalog to any AI agent.
- [Per-user OAuth: bring-your-own-account for MCP](https://katana.orchestration.dev/docs/per-user-oauth): Let each end user authorize their own account on a connector. The gateway stores per-user tokens and runs each call as that user - no shared credentials.

## Guides
- [Connect Claude, Cursor, and ChatGPT](https://katana.orchestration.dev/docs/connect-clients): Step-by-step setup for adding your UCL gateway to Claude Desktop, Cursor, ChatGPT, and headless agents via OAuth, bearer token, or config file.
- [Governance: RBAC, redaction, and per-tool config](https://katana.orchestration.dev/docs/governance): Control exactly what agents can do: role-based access, read-only mode, tool exposure, PHI/PII redaction, and per-tool prompt and field rules.

## Reference
- [Gateway API, headers, and access keys](https://katana.orchestration.dev/docs/api-reference): Reference for the /mcp endpoint, authentication headers (Authorization, X-Org-Id, X-User-Id), access keys, and the per-call identity override.
