    }
  ]
}

4. check_package_compatibility

Check if a Python package supports a specific Python version using PyPI classifier metadata.

Parameters:

• package_name (str): The package name (e.g. "requests")
• python_version (str): The Python version to check (e.g. "3.12")

Example response:

{
  "package": "requests",
  "latest_version": "2.31.0",
  "python_version_checked": "3.12",
  "is_compatible": true,
  "supported_python_versions": ["3", "3.8", "3.9", "3.10", "3.11", "3.12"],
  "requires_python": ">=3.8",
  "compatibility_source": "classifiers"
}

Connect to Claude Desktop

Add the following to your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "developer-tools": {
      "command": "python",
      "args": ["/absolute/path/to/mcp_server.py"]
    }
  }
}

Replace /absolute/path/to/mcp_server.py with the actual absolute path to the file.

After saving, restart Claude Desktop. The four tools will appear in the tools menu (hammer icon).

Connect to Claude Code

Add to your Claude Code settings (.claude/settings.json or project-level):

{
  "mcpServers": {
    "developer-tools": {
      "command": "python",
      "args": ["/absolute/path/to/mcp_server.py"]
    }
  }
}

Or use the CLI:

claude mcp add developer-tools python /absolute/path/to/mcp_server.py
