GMO Coin FX MCP Server

rikitonoto/gmocoin-fx-mcp

Connects Claude to the GMO Coin FX trading API so you can place orders, manage positions, and query account balances directly from conversations. Wraps the full suite of GMO operations: market and limit orders, IFD and IFDOCO combos, bulk cancellations, active order lookups, execution history, and open position monitoring. Ships with safety guards like size limits, symbol whitelists, and client order ID prefixes to scope what Claude can touch. Account assets surface as a read-only MCP resource. Runs over stdio by default with a Docker image ready to go, or switch to HTTP if your setup needs it. Built for developers automating forex trades or building conversational interfaces over live FX positions.
