MCP (Model Context Protocol) servers expose tools that agents can call, such as searching a Notion workspace or reading tickets from an issue tracker. Administrators choose which remote MCP servers are available to the organization. Each user then connects their own account to those servers, so agents act with that user’s permissions.

​
How it works

  1. An admin adds an MCP server in Organization settings → MCP Connectors.
  2. Cake registers itself with the server as an OAuth client.
  3. Each user connects their own account in User settings → MCP Connectors. See Connect to MCP servers.
  4. In that user’s sessions, the agent can call the server’s tools through the Cake MCP server.

​
Requirements

The server must meet these requirements before Cake can add it:
  • It is a remote MCP server that uses the Streamable HTTP transport.
  • Its URL is an absolute https:// URL of up to 2,048 characters, with no embedded credentials (user:pass@) and no fragment (#...).
  • It supports OAuth authorization and publishes protected-resource metadata.
  • Its authorization server supports automatic client registration through Client ID Metadata Documents (CIMD) or Dynamic Client Registration (DCR).
  • Cake can reach it under your egress policy.

​
Add a server

You need the admin role.
  1. Open Organization settings → MCP Connectors.
  2. Under Add an MCP server, enter a Name, for example Notion.
  3. Enter the server URL, for example https://mcp.example.com/mcp.
  4. Select Add server.
Cake contacts the server and registers as an OAuth client before it saves the server. If registration fails, Cake doesn’t save the server and shows the reason under the form.

​
Choose a name

The name labels the server in settings and prefixes its tools for agents. Agents see each tool as <name>.<tool>. For example, a search tool on a server named Notion appears as Notion.search. Names are case-sensitive. Pick a short, unique name for each server, because Cake rejects tool calls when two servers share a name.

​
Remove a server

  1. Open Organization settings → MCP Connectors.
  2. Select the trash icon next to the server.
  3. Select Remove server to confirm.
Agents lose access to the server immediately. You can’t undo this. To restore access, add the server again and ask users to reconnect.
