# MCP Registry Allowlist

Enterprise workspace admins can enforce an MCP registry so that only approved MCP servers are available to
workspace members. If the registry is unreachable, all MCP servers are blocked.
The registry protocol and schema are defined at
[registry.modelcontextprotocol.io](https://registry.modelcontextprotocol.io/docs#/operations/list-servers-v0.1).

**Set the registry URL:**

1. Open [workspace settings](/workspace) and find **MCP Registry**.
2. Enter the registry URL (the `v0.1/servers` endpoint) and save.

**Optionally limit to specific users:**

1. Switch **Apply To** to **Specific users only**.
2. Enter workspace member emails (one per line or comma-separated) and save.

Notes:

- If you scope to specific users, only those users are restricted by the registry; everyone else is unaffected.
- Clear the URL to remove the registry and allow all MCP servers.
