get_webhook
AI agents call get_webhook to retrieve information from CATS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Webhook retrieval is a read-only operation that queries existing webhook configurations without side effects. The empty description limits confidence, but the 'get_' prefix and webhook context strongly indicate a data retrieval operation. Webhooks are typically configuration data, making this a low-severity Read operation.
From the tool's definition Tool name 'get_webhook' suggests retrieval of webhook configuration data. The naming convention aligns with other sibling tools that retrieve or query data (e.g., 'get_*' pattern). No modification, deletion, or execution indicators present.
Attacks that exploit this kind of access
get_webhook. It is categorised as a Read tool in the CATS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CATS MCP Server MCP server in PolicyLayer and add a rule for get_webhook: 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 CATS MCP Server. Nothing to install.
get_webhook 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_webhook 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_webhook. 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_webhook is provided by the CATS MCP Server MCP server (vanman2024/cats-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
