Attacks that exploit this kind of access
List webhook requests captured by a HookRay inbox. It is categorised as a Read tool in the Hookray MCP Server, which means it retrieves data without modifying state.
Register the Hookray MCP server in PolicyLayer and add a rule for list_requests: 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 Hookray. Nothing to install.
list_requests 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_requests 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_requests. 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_requests is provided by the Hookray MCP server (shotatanikawa/hookray-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_requests is one line of Hookray's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
