NexusTrader

Use the exec tool to run bridge.py. Do not write code or call external HTTP APIs directly. bridge.py connects to a local MCP server at 127.0.0.1:18765 (SSE) — all exchange communication goes through that server.

Security Considerations

This skill accesses your exchange API keys. Before using:

• API keys are stored in {NEXUSTRADER_PROJECT_DIR}/.keys/.secrets.toml — a local file, never transmitted by this skill.
• Auto-start is disabled by default. The skill will not start background processes unless you explicitly set NEXUSTRADER_NO_AUTOSTART=0 in the skill's .env file.
• If auto-start is enabled, the NexusTrader-mcp daemon will run in the background and hold access to your API keys.
• Start with testnet/demo keys. Only use real keys after verifying the workflow in a sandbox.
• Orders require explicit user confirmation — verify your agent flow enforces this before live trading.
• See upstream docs for key setup: https://github.com/Quantweb3-com/NexusTrader-mcp
