MCP-404 — MCP endpoint not found

The recovery sequence has exactly three steps. Its stop condition is part of the published record.

MCP-404

Run once, in this order

  1. Confirm the endpoint path matches the integration config (default /v1/mcp).
  2. Check mcp.enabled is not false — a disabled handler returns 404 for GET, POST, and OPTIONS.
  3. Verify the static build used the same SITE_URL as the deployed origin.
