Windsurf Umbra open SAR archive stamp_description

How to: Windsurf Umbra open SAR archive stamp_description

client:Windsurf transport:streamable-http tool:stamp_description

Add Umbra open SAR archive to Windsurf

  1. 01

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

{
  "mcpServers": {
    "umbra-mcp": {
      "serverUrl": "https://api.umbra-py.space/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Umbra open SAR archive'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

Set these first

Umbra open SAR archive will not start until these are set, so stamp_description never becomes available.

  • UMBRA_CANOPY_TOKEN
  • UMBRA_INDEX_DB
  • ANTHROPIC_API_KEY
  • OPENAI_API_KEY

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
