Monzo MCP Server is a Model Context Protocol server that exposes Monzo banking data to Claude for natural-language interactions. It implements a core set of Monzo MCP endpoints, including balance, pots, pot deposits, pot withdrawals, listing transactions, retrieving a transaction, and annotating a transaction. Users can select account types via account_type parameters, with options such as default, personal, prepaid, flex, rewards, and joint. The server can be installed via uv and run with a command, and configured for Claude Desktop by adding the server configuration and ensuring the requests library is included in the --with options. Setup requires a .env file with Monzo credentials: MONZO_ACCESS_TOKEN, MONZO_USER_ID, MONZO_ACCOUNT_ID, and account IDs for specific types. The README also notes certain Monzo MCP features that are not supported by this server. Pot transfers create a dedupe_id including a triggered_by parameter (default 'mcp') to help prevent duplicates. Examples and prompts illustrate typical interactions like asking for a balance, listing pots, moving money into a pot, and viewing transactions.
