AI agents call get_webhook_subscription to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration data about an existing webhook subscription. The verb 'get' and the read-only nature of querying subscription settings confirm this is a Read operation. There is no modification, execution, deletion, or financial impact. Severity is low as webhook subscription metadata poses minimal security risk if exposed to an AI agent.
From the tool's definition Tool name 'get_webhook_subscription' and description 'Get a specific webhook subscription' indicate a retrieval operation with no side effects.

Get a specific webhook subscription. It is categorised as a Read tool in the Filevine MCP Server, which means it retrieves data without modifying state.
Register the Filevine MCP server in PolicyLayer and add a rule for get_webhook_subscription: 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 Filevine. Nothing to install.
get_webhook_subscription 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_subscription 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_subscription. 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.
