Retrieve error count metrics over time. Shows how many errors occurred and whether error rates are trending up or down.
AI agents call get_error_metrics to retrieve information from Monti APM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical error metrics from Monti APM for analysis purposes. It has no side effects—it only queries and returns performance data. The blast radius of misuse is minimal; an agent retrieving error metrics cannot damage systems, modify data, execute code, or trigger financial consequences. This is clearly a Read operation with low severity risk.
From the tool's definition Tool name 'get_error_metrics' and description 'Retrieve error count metrics over time' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Retrieve error count metrics over time. Shows how many errors occurred and whether error rates are trending up or down. It is categorised as a Read tool in the Monti APM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Monti APM MCP Server MCP server in PolicyLayer and add a rule for get_error_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 Monti APM MCP Server. Nothing to install.
get_error_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 get_error_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 get_error_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.
get_error_metrics is provided by the Monti APM MCP Server MCP server (quavedev/montiapm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
