Crypto Market Sentinel

A read-only market anomaly MCP server for Hermes Agent. It watches BTC, ETH, and RENDER, applies volatility-aware P0/P1/P2 thresholds, and emits the shared pif.event.v1 contract for Hermes to deliver through Feishu.

只看公开行情、不接账户、不交易。冷却、迟滞与断线 fail-closed 都在确定性状态机中执行，而不是交给模型猜。

Why / 设计理念

• Alert only when the market changes behavior, not when a price merely changes.

• P0 is immediate; P1 enters a digest; P2 is audit-only.

• Repeats are suppressed for 45 minutes, unless the event escalates to 1.5× threshold.

• A triggered rule must fall below 80% of its threshold before it can rearm.

• Data older than 15 seconds pauses new alerts.

• No account, order, withdrawal, signature, or API Secret surface exists.

Local run

npm ci
npm test
npm run demo

Optional one-shot public Binance snapshot (no API key):

node src/cli.js --live BTC

If Binance is unavailable in the current network, the command exits safely; deterministic demo and MCP tools remain available.

Add to Hermes on macOS

git clone https://github.com/roclee2692/crypto-market-sentinel.git ~/Projects/crypto-market-sentinel
cd ~/Projects/crypto-market-sentinel && npm ci
hermes mcp add market-sentinel --command node --args "$HOME/Projects/crypto-market-sentinel/src/mcp.js"
hermes mcp test market-sentinel

Hermes exposes names such as mcp_market_sentinel_evaluate_market_snapshot. The MCP returns a Feishu-ready message; Hermes keeps using the Feishu channel you already configured.

Tools

• evaluate_market_snapshot

• simulate_market_scenario

• get_market_policy

The companion repository is email-triage-agent. Both use the same urgent/digest/audit event envelope.
