update_webhook · Eduframe MCP: Risk & Policy

WHAT IT DOES

What update_webhook does on Eduframe

AI agents use update_webhook to create or update resources in Eduframe — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Eduframe environment.

WHY IT NEEDS A POLICY

Why update_webhook needs a policy

Webhooks are configuration endpoints that receive callbacks. Updating a webhook modifies its settings (URL, events, headers, etc.) reversibly without deleting data. This is a Write operation. Severity is medium because a compromised webhook update could redirect API notifications to an attacker's server, enabling information disclosure or downstream attacks, but the change is reversible.

From the tool's definition Tool name 'update_webhook' and description 'Update a webhook' indicate modification of existing webhook configuration data.

Verdict

update_webhook Rate-limited

update_webhook stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
