Return aggregate stats for your active URLs: total count and total estimatedTokensSaved across all of them. Use this to get a quick summary without loading the full URL list.
AI agents call get_stats to retrieve information from Url Shortener without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries aggregated metrics (total count and estimatedTokensSaved) from the URL shortener system without any side effects. It is a pure read operation that gathers information for display purposes only. No data is created, modified, deleted, or executed.
From the tool's definition Tool description states 'Return aggregate stats' and 'get a quick summary' — these are retrieval operations with no modification, deletion, or execution of external processes. The data returned is read-only statistical summaries.
Attacks that exploit this kind of access
Return aggregate stats for your active URLs: total count and total estimatedTokensSaved across all of them. Use this to get a quick summary without loading the full URL list. It is categorised as a Read tool in the Url Shortener MCP Server, which means it retrieves data without modifying state.
Register the Url Shortener MCP server in PolicyLayer and add a rule for get_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 Url Shortener. Nothing to install.
get_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_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_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_stats is provided by the Url Shortener MCP server (michaelshumshum/url-shortener-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
