Get circuit breaker status for all proxied targets
AI agents call selfheal_circuits to retrieve information from SelfHeal MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves monitoring/observability data about circuit breaker status across proxied services. It performs no mutations, does not execute code, and has no side effects—purely informational. Appropriate for a self-healing proxy's observability layer.
From the tool's definition Tool name 'selfheal_circuits' and description 'Get circuit breaker status for all proxied targets' indicate a query operation that retrieves status information without modifying state.
Attacks that exploit this kind of access
Get circuit breaker status for all proxied targets. It is categorised as a Read tool in the SelfHeal MCP MCP Server, which means it retrieves data without modifying state.
Register the SelfHeal MCP server in PolicyLayer and add a rule for selfheal_circuits: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SelfHeal MCP. Nothing to install.
selfheal_circuits is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the selfheal_circuits 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.
Set action: deny in the PolicyLayer policy for selfheal_circuits. 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.
selfheal_circuits is provided by the SelfHeal MCP server (selfheal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
