RECOMMENDED RULE

The rule that runs get_change_impact safely

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

get_change_impact Allowed

get_change_impact is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Trace, apply this rule, and every get_change_impact call is checked against it from then on.

Questions about get_change_impact

What does the get_change_impact tool do? +

Full change impact report: risk score + mitigations, breaking change detection, enriched dependents (complexity, coverage, exports), module groups, affected tests, co-change hidden couplings. Pass symbol_ids to scope to changed symbols. Use before modifying code. For a quick risk score alone use assess_change_risk; for who-calls-what use get_call_graph. compact pages results; bundle recalls. Read-only. Returns JSON: { risk, dependents, affectedTests, breakingChanges, totalAffected }. It is categorised as a Read tool in the Trace MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_change_impact? +
