AI agents call list-astro-routes to retrieve information from Astro 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 list-astro-routes 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 list-astro-routes gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
List detailed routing information from your Astro project, including all routes with their file entrypoints, URL patterns, dynamic parameters, pre-rendering status, and route types. Optionally filter by type to focus on specific route categories. It is categorised as a Read tool in the Astro MCP Server, which means it retrieves data without modifying state.
Register the Astro MCP server in PolicyLayer and add a rule for list-astro-routes: 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 Astro. Nothing to install.
list-astro-routes 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 list-astro-routes 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 list-astro-routes. 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.
list-astro-routes is provided by the Astro MCP server (astro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
