RISK

Why today_rhythm is rated Low

Without any rule in front of it, every call an agent makes to today_rhythm happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs today_rhythm safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Balance Engine, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For today_rhythm, this is the rule to start with:

today_rhythm Rate-limited

today_rhythm gets a rate cap, and everything else on the server is denied unless you say otherwise.

FAQ

Questions about today_rhythm

What does the today_rhythm tool do? +

This tool looks up a deterministic rules engine. Same day → same answer. Do not invent pillars or fortune claims. Call when the user asks 今天节奏怎么样 / 今天势能怎么样 / 今天干支是什么 / 今天适不适合签约开会发版 / 今天流通怎么样 / 该不该推进某事 / what is today's rhythm. Returns east pillars, this month’s fold year (same pillar), month posture × west tightness as do/don't, plus the daily west almanac. Always surface the fold-year line and ask what they lived that year. Public · local · no API key. Preview ≠ prediction. It is categorised as a Other tool in the Balance Engine MCP Server, which means it performs auxiliary operations.
