FAQ from Maigret MCP Server

What are the system requirements?

Node.js v18 or later, Docker (with Docker Desktop on macOS/Windows), and write access to a reports directory.

How do I install and configure the server?

Install globally via npm (npm install -g mcp-maigret) or set up from source. Create a reports directory and set the MAIGRET_REPORTS_DIR environment variable in your Claude Desktop configuration file.

What security measures are in place?

Usernames are restricted to alphanumeric, underscores, hyphens, and periods (max 100 chars); URLs must be valid HTTP/HTTPS with no shell metacharacters; tags allow only alphanumeric, underscores, and hyphens. Commands use execFile() to prevent shell injection.

What output formats does the username search support?

Txt, html, pdf, json, csv, and xmind. The default format is pdf.

How can I troubleshoot Docker or reports directory issues?

Verify Docker is installed and running (docker --version, docker ps). Ensure the MAIGRET_REPORTS_DIR path exists and your user has write permissions. Common fixes include checking permissions, removing trailing slashes, and restarting Claude Desktop after changes.
