Overview

What is MTG Assistant?

MTG Assistant is a Model Context Protocol server that fetches Magic: The Gathering card information using the Scryfall API. It is intended for developers integrating MTG card lookups into MCP-compatible clients such as Claude.

How to use MTG Assistant?

Install dependencies with uv, then run uv run mcp-server-mtg-assistant from the project directory. Alternatively, install via pip install mcp-server-mtg-assistant and run python -m mcp_server_mtg_assistant. Add a configuration entry to your MCP client (e.g., mcp.json) with uv or wsl.exe commands and the correct --directory path. The server exposes one tool: get_mtg_card_info, which accepts a search query string.

Frequently asked questions

What data source does MTG Assistant use?

It retrieves card information from the Scryfall API, a public database of Magic: The Gathering cards.

What are the runtime requirements?

The server requires Python and the `uv` package manager (recommended). It can also be run via `pip` if the package is published.

How do I configure MTG Assistant for Windows with a WSL server?

Use `wsl.exe` as the command with the path to `uv` inside WSL, and a WSL‑style path (e.g., `/mnt/d/...`) for the `--directory` argument.

What should I do if I get a `.venv` conflict when switching between environments?

Delete the `.venv` directory in the project root before switching environments. The next `uv run` will create a fresh, compatible virtual environment.

How can I debug the MTG Assistant server?

Run the MCP inspector by prefixing your server command with `npx @modelcontextprotocol/inspector`. Example: `npx @modelcontextprotocol/inspector uv --directory <project_path> run mcp-server-mtg-assistant`.
