How to: Windsurf PreReason macro_regime_check

Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

"mcp": {
"serverUrl": "https://api.prereason.com/api/mcp"
}
}
}-
02
Save the file and restart Windsurf.

03
macro_regime_check is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Windsurf will not call it for you.
-
04
If it does not appear, check that PreReason is connected and that you are looking at its prompts rather than its tools.
Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs
Set these first
PreReason will not start until these are set, so it never reaches Windsurf.

Same prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026.
A listing does not declare its prompts, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each prompt's arguments.
