Show compression statistics: total items stored, bytes saved, overall compression ratio.
AI agents call stats to retrieve information from Mcp Compress without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and reports statistics about compression operations. It reads and presents metadata and metrics without creating, modifying, deleting data, executing code, or triggering external operations. The low severity reflects minimal blast radius: misuse would only expose compression statistics, not cause harm to data or systems.
From the tool's definition Tool name 'stats' and description 'Show compression statistics' indicate retrieval and aggregation of stored metrics—'total items stored, bytes saved, overall compression ratio'—with no modification or destructive capability.
Attacks that exploit this kind of access
Show compression statistics: total items stored, bytes saved, overall compression ratio. It is categorised as a Read tool in the Mcp Compress MCP Server, which means it retrieves data without modifying state.
Register the Mcp Compress MCP server in PolicyLayer and add a rule for 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 Mcp Compress. Nothing to install.
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 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 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.
stats is provided by the Mcp Compress MCP server (shipitandpray/mcp-compress). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
stats is one line of Mcp Compress's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
