WHAT IT DOES

What update_source does on Automagik Tools

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

RISK

Why update_source is rated Medium

This tool modifies workflow source configurations, which is a Write operation (creates or modifies data reversibly). The severity is medium because misconfigured sources could impact workflow behavior and potentially expose or redirect data flows, but the operation itself is reversible.

From the tool's definition Tool name 'update_source' and description 'Update a workflow source configuration' indicate modification of existing configuration data. The verb 'update' is explicitly mentioned, which is a reversible write operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_source safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Automagik Tools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_source, this is the rule to start with:

update_source Rate-limited

update_source 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.
