AI agents call list_transformations to retrieve information from Zhook without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing transformation configurations associated with a webhook. It performs a data lookup operation without creating, modifying, deleting, or executing any actions. The verb 'list' and the read-only nature of the operation clearly indicate a Read category classification. Severity is low because retrieving configuration metadata poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'list_transformations' and description 'List all transformations configured for a specific webhook' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all transformations configured for a specific webhook. It is categorised as a Read tool in the Zhook MCP Server, which means it retrieves data without modifying state.
Register the Zhook MCP server in PolicyLayer and add a rule for list_transformations: 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 Zhook. Nothing to install.
list_transformations 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_transformations 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_transformations. 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_transformations is provided by the Zhook MCP server (zhookteam/zhook-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_transformations is one line of Zhook's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
