WHAT IT DOES

What add_from_file does on Elevenlabs

AI agents use add_from_file 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	The name of the pronunciation dictionary, used for identification only.
`file_path`	string	—	A lexicon .pls file which we will use to initialize the project with. Local path.
`description`	string \| null	—	A description of the pronunciation dictionary, used for identification only.
`file_base64`	string	—	Base64 contents for "file". Use this when the server cannot read your local disk.
`file_filename`	string	—	Filename to send for "file". Some endpoints infer the audio format from it.
`workspace_access`	object	—	Should be one of 'admin', 'editor' or 'viewer'. If not provided, defaults to no access.

Parameters from the server's own tool schema.

RECOMMENDED RULE

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

add_from_file Rate-limited

add_from_file 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 add_from_file call is checked against it from then on.
