WHAT IT DOES

What set_rules does on Elevenlabs

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

Parameter	Type	Required	Description
`rules`	array	Yes	List of pronunciation rules. Rule can be either: an alias rule: {'string_to_replace': 'a', 'type': 'alias', 'alias': 'b', } or a phoneme rule: {'string_to_repla
`pronunciation_dictionary_id`	string	Yes	The id of the pronunciation dictionary

Parameters from the server's own tool schema.

RISK

Why set_rules is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_rules safely

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

set_rules Rate-limited

set_rules 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.
