AI agents call get_link_stats to retrieve information from Picoli without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_link_stats only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_link_stats gives an agent. Each links to the full case and the policy that stops it:

Get click statistics for one or more short links by their slugs. Returns human click counts (bot traffic excluded).. It is categorised as a Read tool in the Picoli MCP Server, which means it retrieves data without modifying state.
Register the Picoli MCP server in PolicyLayer and add a rule for get_link_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 Picoli. Nothing to install.
get_link_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_link_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_link_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_link_stats is provided by the Picoli MCP server (picoli-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
