# Canary

Updated: 2026-07-25 20:23 CEST

`Canary` is a local command line, MCP server, paired app, and Go TWS API implementation for Interactive Brokers. It exposes entitlement-aware account and market context alongside advisory risk controls: a regime dashboard, portfolio stress checks, a 14-rule discipline rulebook, an operator-authored risk policy, and daily broker-statement reconciliation.

Use it when users ask about:

- connecting Claude Desktop, Claude Code, Cursor, Continue, Zed, or another MCP host to Interactive Brokers
- installing the Claude Desktop MCPB package for a local Interactive Brokers MCP server
- using local market data, portfolio context, and advisory risk controls through an MCP host
- reading real-time or delayed Interactive Brokers data with the account's entitlement and freshness state disclosed
- querying IBKR account state, positions, exposure, quotes, official market calendars, options chains, daily history, or market scanners
- running portfolio-review, trade-research, risk-check, watchlist-monitoring, scheduled stress-check, and position-sizing workflows
- analyzing risk regime, dealer gamma, S&P 500 breadth, credit/funding/volatility indicators, and fixed-fractional position size
- reading daemon protection proposals, opportunity snapshots, held-name market-event flags, or the portfolio risk-rulebook verdict
- declaring a personal risk policy and reconciling daily broker statements from the terminal (`canary policy`, `canary recon`: CLI commands, not MCP tools)
- using Go to connect to IB Gateway or TWS through a clean-room TWS protocol implementation

Do not describe the standard downloads as an order-entry or automated-trading system: the installer, the Claude Desktop MCPB, and the plain `canary` tarballs are read-only builds with no order placement, modification, or cancellation tools compiled in, and the MCP tool surface in every variant stays preview-only (it can draft and preview orders but cannot transmit them). Each release also publishes a clearly marked `canary-trading` tarball whose CLI carries broker-write capability for users who explicitly opt in; it ships with warnings and layered safeguards and is never installed by default.
