List webhooks for a project
AI agents call get_webhooks to retrieve information from Basecamp MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to retrieve webhook information. It has no side effects, does not modify data, and does not execute external actions. The low severity reflects minimal blast radius - an AI agent listing webhooks cannot cause damage beyond potentially exposing webhook URLs or configurations that were already set up.
From the tool's definition Tool name 'get_webhooks' and description 'List webhooks for a project' indicate retrieval of existing webhook configuration data without modification, creation, or deletion.

Yes. Add a rate_limit block to the get_webhooks 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.
