Get performance and cache statistics
AI agents call get_performance_stats to retrieve information from Markdown3D 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 performance metrics and cache statistics, which is purely informational. It has no capability to modify, delete, or execute operations. The blast radius of misuse is minimal — an agent could only gain information about system performance, posing no risk to data integrity, financial systems, or destructive operations.
From the tool's definition Tool name is 'get_performance_stats' and description states it retrieves 'performance and cache statistics' — a read-only operation that queries existing data without modification or side effects.

Get performance and cache statistics. It is categorised as a Read tool in the Markdown3D MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Markdown3D MCP Server MCP server in PolicyLayer and add a rule for get_performance_stats: 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 Markdown3D MCP Server. Nothing to install.
get_performance_stats 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_performance_stats 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_performance_stats. 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_performance_stats is provided by the Markdown3D MCP Server MCP server (mushroomfleet/markdown3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
