Windsurf SumOffice — real Word and Excel for agents document_open

How to: Windsurf SumOffice — real Word and Excel for agents document_open

client:Windsurf transport:streamable-http tool:document_open

Add SumOffice — real Word and Excel for agents to Windsurf

  1. 01

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

{
  "mcpServers": {
    "office": {
      "serverUrl": "https://view.sumoffice.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that SumOffice — real Word and Excel for agents'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.
