Setup by Tool¶

Configuration snippets for each AI tool that supports MCP. Replace the path to the binary and provide your API key via environment variable or .env file.

GitHub Copilot CLI / Claude Code¶

Add to .mcp.json in your project or home directory:

{
  "mcpServers": {
    "psi": {
      "type": "stdio",
      "command": "/path/to/psi-mcp-go-linux-amd64",
      "args": [],
      "env": {
        "GOOGLE_PSI_API_KEY": "your-api-key"
      }
    }
  }
}

Note

Some MCP clients (including GitHub Copilot CLI) require "args": [] when "type": "stdio" is specified. Claude Desktop does not require it.

Claude Desktop¶

Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):

{
  "mcpServers": {
    "psi": {
      "command": "/path/to/psi-mcp-go-linux-amd64",
      "env": {
        "GOOGLE_PSI_API_KEY": "your-api-key"
      }
    }
  }
}

Cursor¶

Add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "psi": {
      "command": "/path/to/psi-mcp-go-linux-amd64",
      "args": [],
      "env": {
        "GOOGLE_PSI_API_KEY": "your-api-key"
      }
    }
  }
}

VS Code¶

Add to .vscode/mcp.json:

{
  "servers": {
    "psi": {
      "type": "stdio",
      "command": "/path/to/psi-mcp-go-linux-amd64",
      "args": [],
      "env": {
        "GOOGLE_PSI_API_KEY": "your-api-key"
      }
    }
  }
}

Visual Studio¶

Add to the MCP configuration in Visual Studio's GitHub Copilot settings:

{
  "mcpServers": {
    "psi": {
      "type": "stdio",
      "command": "C:\\path\\to\\psi-mcp-go-windows-amd64.exe",
      "args": [],
      "env": {
        "GOOGLE_PSI_API_KEY": "your-api-key"
      }
    }
  }
}

Using a .env File¶

Place a .env file in the same directory as the binary:

GOOGLE_PSI_API_KEY=your-api-key

Then the env block in your tool config can be omitted. The binary reads .env automatically from its working directory.

Using a CLI Argument¶

Pass the key directly on the command line:

./psi-mcp-go-linux-amd64 --api-key your-api-key
