Windsurf FastBill MCP by usefulapi fastbill_list_revenues

How to: Windsurf FastBill MCP by usefulapi fastbill_list_revenues

client:Windsurf transport:streamable-http tool:fastbill_list_revenues

Add FastBill MCP by usefulapi to Windsurf

  1. 01

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

{
  "mcpServers": {
    "fastbill": {
      "serverUrl": "https://fastbill.usefulapi.io/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that FastBill MCP by usefulapi'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 26 October 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.
