WHAT IT DOES

What update_contact does on Automagik Tools

AI agents use update_contact 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_contact is rated Medium

The tool modifies existing contact records reversibly without deleting data or executing code. This is a classic Write operation. Severity is medium because contact information is personal data whose modification could affect communication or identity verification, but the operation is reversible and limited to contact record fields.

From the tool's definition Tool name 'update_contact' and description 'Update existing contact in local database' with parameters for phone_number, name, nickname, notes indicate data modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_contact 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_contact, this is the rule to start with:

update_contact Rate-limited

update_contact 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.
