WHAT IT DOES

What uxi_update_agent does on API-Central

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

RISK

Why uxi_update_agent is rated Medium

This is a Write operation because it modifies agent metadata/notes but does not delete data or execute arbitrary code. The blast radius is medium because unauthorized updates to agent notes or metadata could impact network monitoring/management operations, but the scope is limited to editable fields on a single agent resource.

From the tool's definition Tool performs a PATCH operation on UXI agent editable fields (e.g. notes) by ID, which constitutes modification of existing data. Description uses 'update' indicating reversible change.

RECOMMENDED RULE

The rule that runs uxi_update_agent safely

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

uxi_update_agent Rate-limited

uxi_update_agent 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.
