Replaces the stub /metrics endpoint with a real prom-client registry
(mana_mcp_ prefix, {service="mana-mcp"} default label). Default
process metrics come along for free.
Policy-gate telemetry is the whole point — without it we can't soak
POLICY_MODE=log-only safely or decide when to flip to enforce. New
counter mana_mcp_policy_decisions_total{decision, reason, mode} buckets
every evaluatePolicy() call:
decision ∈ {allow, deny, flagged}
reason ∈ {admin-scope-not-invokable, destructive-not-allowed,
rate-limit-exceeded, injection-marker, clean, unknown}
mode ∈ {log-only, enforce}
So the rate of "would have been denied" during soak is visible directly
as policy_decisions_total{decision="deny", mode="log-only"}.
Also:
- mana_mcp_tool_invocations_total{tool, outcome} — success |
handler-error | input-invalid. Policy denies are NOT counted here
(they're in policy_decisions_total above); this counter only counts
calls that actually reached the handler or tripped zod validation.
- mana_mcp_tool_duration_seconds histogram per tool/outcome.
Dep: prom-client ^15.1.3 (same version mana-ai pins).
