Hi @Jack Bao ,

If you’re using on-prem (OutSystems 11), there isn’t a built-in way to connect to an MCP server like there is in ODC.

In ODC, you can just set it up through the portal, but on-prem you’ll need to handle it yourself. The easiest way is to treat the MCP server like a normal external API:

• Call it using REST
• Use the MCP server URL (like /mcp or /sse)
• Handle authentication (API key, OAuth, etc.)
• Then trigger the tools from there

Also double-check things like headers and whether the server expects HTTP or SSE - that’s where people usually get stuck.
