FAQ from Monad Custom Agent (MCP Server for Cursor)

What runtime and dependencies are required?

Python 3.11+ with libraries: mcp (FastMCP), web3.py, httpx, click, python-dotenv, and API clients for Zerion, Magic Eden, and Thirdweb.

What external APIs does the server use?

It uses the Monad Testnet RPC (direct), Zerion API (balances, transactions), Magic Eden API (NFT stats, activity, trends), and Thirdweb Insight API (contract ABIs). Some tools require the corresponding API key to be set.

Where does the blockchain data come from?

Data is sourced live from the Monad Testnet via its RPC endpoint, from indexed data provided by Zerion, from Magic Eden for NFT marketplace information, and from Thirdweb for verified contract metadata.

What MCP transports or authentication are supported?

The server runs as an MCP server and is intended to be connected to by Cursor or Claude Desktop. Authentication is handled via API keys passed as environment variables (ZERION_API_KEY, MAGIC_EDEN_API_KEY, THIRDWEB_CLIENT_ID). No other transports (e.g., HTTP) are mentioned.

Are there any limitations or known issues?

The README does not list explicit limitations, but note that the Magic Eden and Zerion tools require valid API keys, and the Thirdweb ABI fetching depends on a client ID. The server is designed for the Monad Testnet only, not for mainnet.
