What update_a_policy does on Acronis Platform

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

`path`	object	Yes	URI path parameters

Parameters from the server's own tool schema.

RISK

Why update_a_policy is rated Medium

An AI agent can call update_a_policy faster than any human can review: one bad instruction and it creates or modifies resources in Acronis Platform by the hundred, each call as confident as the last.

Risk signalsAccepts freeform code/query input (body.subject.policy[]._issues[].error.code) · Accepts file system path (path) · Accepts raw HTML/template content (body) · High parameter count (76 properties)

RECOMMENDED RULE

The rule that runs update_a_policy safely

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

update_a_policy Rate-limited

update_a_policy 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.
