Get caching system statistics and performance metrics
AI agents call server.get_cache_stats to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries internal cache performance data for observability purposes. It retrieves information without modifying, executing code, deleting data, or affecting external systems. The blast radius of misuse is minimal—an AI agent could only over-call the endpoint or leak timing information about cache behavior. No configuration changes, data mutations, or external operations are possible.
From the tool's definition Tool name and description indicate retrieval of statistics and metrics: 'Get caching system statistics and performance metrics'. The verb 'Get' and nouns 'statistics' and 'metrics' denote read-only data retrieval with no side effects.
Attacks that exploit this kind of access
Get caching system statistics and performance metrics. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for server.get_cache_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 ContextForge MCP Gateway. Nothing to install.
server.get_cache_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 server.get_cache_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 server.get_cache_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.
server.get_cache_stats is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
