WHAT IT DOES

What circuit_reset does on PM-MCP (Portfolio Management MCP Server)

AI agents invoke circuit_reset to trigger actions in PM-MCP (Portfolio Management MCP Server). What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why circuit_reset needs a policy

A circuit breaker reset triggers a state change in an operational safety/control mechanism. This is an Execute-level action: it modifies the runtime state of external systems (circuit breakers) and can have broad blast radius if all breakers are reset simultaneously (re-enabling previously blocked operations).

From the tool's definition '서킷 브레이커 리셋 (name 미지정 시 전체 리셋)' — resets circuit breaker(s), optionally resetting all if no name is specified

Verdict

circuit_reset Rate-limited

circuit_reset stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches PM-MCP (Portfolio Management MCP Server). Nothing to install.

What risk level is circuit_reset? +

circuit_reset is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit circuit_reset? +

Yes. Add a rate_limit block to the circuit_reset rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block circuit_reset completely? +

Set action: deny in the PolicyLayer policy for circuit_reset. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides circuit_reset? +

circuit_reset is provided by the PM-MCP (Portfolio Management MCP Server) MCP server (surplus96/pm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
