AI agents call get-webhook to retrieve information from Mcp Dev without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves webhook configuration data from the Umbraco CMS system. It performs a query operation with pagination, returning existing data without creating, modifying, deleting, or executing any changes. The operation has no side effects and poses minimal risk to the system, making it a straightforward Read category tool.
From the tool's definition Tool name 'get-webhook' and description 'Gets a paged list of webhooks' indicate data retrieval without modification. The verb 'Gets' and context of fetching a 'paged list' are characteristic of read-only operations.
Attacks that exploit this kind of access
Gets a paged list of webhooks. It is categorised as a Read tool in the Mcp Dev MCP Server, which means it retrieves data without modifying state.
Register the Mcp Dev 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 Mcp Dev. 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 Mcp Dev MCP server (@umbraco-cms/mcp-dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
