AI agents call page_get to retrieve information from Meta without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves page metadata from Meta's Graph API without modifying, executing operations, or creating side effects. The read-only nature of the server and the GET operation semantics place it firmly in the Read category with low severity, as metadata retrieval presents minimal risk even if misused by an AI agent.
From the tool's definition Tool description explicitly states 'GET /{page_id} — page metadata' and server is described as 'Read-only MCP server'. The GET HTTP method and retrieval of metadata confirm read-only behavior with no side effects.
Attacks that exploit this kind of access
GET /{page_id} — page metadata. It is categorised as a Read tool in the Meta MCP Server, which means it retrieves data without modifying state.
Register the Meta MCP server in PolicyLayer and add a rule for page_get: 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 Meta. Nothing to install.
page_get 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 page_get 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 page_get. 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.
page_get is provided by the Meta MCP server (nourpups/meta-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
