    Frequently asked questions

    How do I install Filesystem MCP?▼

    Copy the config above into your AI assistant's MCP settings file:

    • Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Cursor: Settings → MCP → Add Server
    • VS Code: .vscode/mcp.json
    Does it require an API key?▼

    No. Filesystem MCP is free to test. No API key or signup required. We tested it independently.

    How were these results measured?▼

    We run each server through a standardized test harness that:

    1. Installs the server via npx in a fresh environment
    2. Discovers available tools using the MCP SDK
    3. Executes real tasks (navigate, click, screenshot, etc.)
    4. Validates outputs with semantic assertions (not string matching)
    5. Measures latency percentiles and pass rate

    All test scripts are open source on GitHub.
