Check your current usage quota.
AI agents call usage_stats to retrieve information from Prospector MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays quota statistics about the user's consumption. It has no side effects, does not execute code, does not modify data, and does not consume or commit resources. It is purely informational/diagnostic.
From the tool's definition Tool name 'usage_stats' and description 'Check your current usage quota' indicate a read-only query operation that retrieves usage information without modifying, executing, or affecting any data or systems.
Attacks that exploit this kind of access
Check your current usage quota. It is categorised as a Read tool in the Prospector MCP MCP Server, which means it retrieves data without modifying state.
Register the Prospector MCP server in PolicyLayer and add a rule for usage_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 Prospector MCP. Nothing to install.
usage_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 usage_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 usage_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.
usage_stats is provided by the Prospector MCP server (josiebot26/prospector-mcp-email-finder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
