TRA — Claude Code MCP server: what it does, how to install
An MCP server for autonomous trading agents where models only propose ideas, leaving market data, pricing, and execution to deterministic code.
claude mcp add bitra -- uvx bitraWhat TRA does
The server separates market reasoning from financial calculation. Language models review market conditions and share an opinion, but they cannot perform arithmetic, access private keys, or submit orders directly. Fixed code fetches live data, evaluates round-trip expenses like spreads and fees, and enforces hard risk boundaries.
Running the tool requires Python 3.11 or newer along with an API key from a supported model provider. Orders clear only when the projected edge covers transaction costs, and every accepted or rejected decision is saved directly to disk.
What it helps with
- block trades where expected margins do not cover transaction costs and slippage
- prevent model hallucinations from directly sizing positions or executing orders
- keep trade stops and target orders linked together upon venue entry
- record every agent proposal and system refusal to disk for post-trade reviews
Example prompts for the agent
- Inspect the latest market data and retrieve agent proposals via tra
- Check round-trip execution costs and position sizing for the selected trading pair
