Other MCP clients

Every MCP client needs the same three things:

The transport is stdio: the client starts the command and talks to it directly.

VS Code

In .vscode/mcp.json:

{
  "servers": {
    "costcrunch": {
      "type": "stdio",
      "command": "uvx",
      "args": ["--from", "costcrunch", "cost", "mcp"],
      "env": { "COSTCRUNCH_API_KEY": "cc_live_..." }
    }
  }
}

Windsurf and others

Use the mcpServers format from Cursor, in the file your client documents (Windsurf: ~/.codeium/windsurf/mcp_config.json).

Without uv

Install the package with pip install costcrunch, then use cost as the command and mcp as the only argument.
