create_webhook · Eduframe MCP: Risk & Policy

WHAT IT DOES

What create_webhook does on Eduframe

AI agents use create_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 create_webhook needs a policy

Creating a webhook registers a new event handler that will trigger external HTTP callbacks. This is a write operation because it creates a new resource (webhook configuration) that can be modified or deleted later. Severity is medium because webhooks can expose sensitive data flows and create unintended side effects if misconfigured (e.g., leaking data to external URLs), but the operation itself is reversible.

From the tool's definition Tool named 'create_webhook' with description 'Register a webhook.' The action creates a new webhook configuration, which is a reversible write operation that modifies system state by adding a new integration point.

Verdict

create_webhook Rate-limited

create_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.
