WHAT IT DOES

What update_agent does on Freshdesk

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

RISK

Why update_agent is rated Medium

The tool modifies an existing agent's configuration or properties in Freshdesk, which is characteristic of Write operations. While agent updates could impact support operations, the action is reversible (agents can be updated again or reverted), making it Write rather than Execute or Destructive.

From the tool's definition Tool name 'update_agent' and description 'Update an existing agent' indicate modification of existing agent data/configuration. This is a write operation that creates or modifies data reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_agent safely

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

update_agent Rate-limited

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.
