Windsurf MCPFax Agent Continuity watermark_set

How to: Windsurf MCPFax Agent Continuity watermark_set

client:Windsurf transport:streamable-http tool:watermark_set

Add MCPFax Agent Continuity to Windsurf

  1. 01

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

{
  "mcpServers": {
    "agent-continuity": {
      "serverUrl": "https://mcpfax-continuity.bowling-anthony.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something watermark_set does. Windsurf lists the server's tools on connect and calls watermark_set itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that MCPFax Agent Continuity's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
