AI agents call get-page to retrieve information from Zeroheight 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-page 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-page 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.
Call this BEFORE generating UI that uses a documented component, pattern, or guideline. Returns the page's usage notes, recommendations, prop and variant guidance, supporting context, and any file attachments. Treat the response as the source of truth — do not invent props, variants, or usage patterns that are not documented here. *If images from the page are needed, call get-page-images afterwards with the same page ID to retrieve them as base64-encoded content. Non-image attachments are linked inline in the page content and can be shared with the user by URL.*. It is categorised as a Read tool in the Zeroheight MCP Server, which means it retrieves data without modifying state.
Register the Zeroheight MCP server in PolicyLayer and add a rule for get-page: 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 Zeroheight. Nothing to install.
get-page 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-page 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-page. 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-page is provided by the Zeroheight MCP server (https://mcp.zeroheight.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
