Get SelfHeal proxy metrics — success rates, latency, top errors
AI agents call selfheal_metrics 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 queries and returns observability/monitoring data about the SelfHeal proxy's performance. It has no side effects, does not modify state, execute code, or perform destructive actions. It is purely informational. The blast radius of an AI agent misusing this is minimal — at worst, excessive metric queries could impact logging/monitoring systems, but the tool itself is read-only.
From the tool's definition Tool name 'selfheal_metrics' and description 'Get SelfHeal proxy metrics' — explicitly a retrieval operation. Described as retrieving 'success rates, latency, top errors' with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Get SelfHeal proxy metrics — success rates, latency, top errors. 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_metrics: 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_metrics 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_metrics 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_metrics. 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_metrics 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.
