WHAT IT DOES

What merge_preview_route does on Elevenlabs

AI agents use merge_preview_route 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
`force`	boolean	—	When true, source branch changes always win conflicts regardless of timestamps
`agent_id`	string	Yes	The id of an agent. This is returned on agent creation.
`source_branch_id`	string	Yes	Unique identifier for the source branch to merge from.
`target_branch_id`	string	Yes	The ID of the target branch to merge into.

Parameters from the server's own tool schema.

RISK

Why merge_preview_route is rated Medium

An AI agent can call merge_preview_route 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.

RECOMMENDED RULE

The rule that runs merge_preview_route 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 merge_preview_route, this is the rule to start with:

merge_preview_route Rate-limited

merge_preview_route 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.
