AI agents call analisar_performance to retrieve information from Maestro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name translates from Portuguese as 'analyze_performance', which implies a read/query operation to assess performance metrics. However, the description is effectively empty ('Interno Use'), providing no detail about side effects. Based on the naming pattern consistent with sibling tools like 'analisar', 'analisar_qualidade', 'analisar_seguranca' (all analysis tools), this is likely a read-only analysis tool.
From the tool's definition Tool name 'analisar_performance' suggests analysis/read operation; description is '[Interno] Use' which is uninformative.

Register the Maestro MCP server in PolicyLayer and add a rule for analisar_performance: 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 Maestro. Nothing to install.
analisar_performance 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 analisar_performance 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 analisar_performance. 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.
analisar_performance is provided by the Maestro MCP server (matheus-gama-deluna/maestro). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
