WHAT IT DOES

What schedule_line_publish does on EchoRelay

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

Parameter	Type	Required
`lineKey`	string	Yes
`scheduledAt`	string	Yes
`draftRevision`	integer	Yes

Parameters from the server's own tool schema.

RISK

Why schedule_line_publish is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs schedule_line_publish safely

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

schedule_line_publish Rate-limited

schedule_line_publish 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.
