WHAT IT DOES

What create_finetune does on Elevenlabs

AI agents use create_finetune 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
`name`	string	Yes	Name for the finetune (5-200 characters).
`tags`	array	—	Tags to associate with the finetune.
`model_id`	string	—
`visibility`	object	—	Finetune visibility. Only 'private' and 'workspace' can be set.
`files_paths`	array	—	Audio files to train on. Local paths.
`primary_genre`	string	Yes	Primary musical genre of the finetune.
`files_filenames`	array	—	Filenames to send for "files". Some endpoints infer the audio format from them.
`files_base64_list`	array	—	Base64 contents for "files", one entry per file. Use this when the server cannot read your local disk.

Parameters from the server's own tool schema.

RECOMMENDED RULE

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

create_finetune Rate-limited

create_finetune 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.

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Elevenlabs, apply this rule, and every create_finetune call is checked against it from then on.
