Custom connections (MCP)

Give an agent tools from any app that has an MCP server, like custom connectors in ChatGPT or Claude. Admins add them on the agent's Connect tab.

1. 1
   Open New custom connection and give it a short name.
2. 2
   Paste the MCP server URL (streamable HTTP).
3. 3
   Choose its sign-in: none, a Bearer API key, or a key in a custom header.
4. 4
   Tick that you trust it, then save. Its tools are read and listed.
5. 5
   Switch off any tools the agent shouldn't use.

On calls

Each tool is available to the agent; it says a hold line while one runs.

Refresh tools

Re-reads the server's tools after it changes.

Test calls

Only tools the server marks read-only really run.
