WHAT IT DOES

What forced_alignment does on Elevenlabs

AI agents use forced_alignment 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
`text`	string	Yes	The text to align with the audio. The input text can be in any format, however diarization is not supported at this time.
`file_path`	string	—	The file to align. All major audio formats are supported. The file size must be less than 1GB. Local path. Required for this call.
`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.

Parameters from the server's own tool schema.

RISK

Why forced_alignment is rated Medium

An AI agent can call forced_alignment 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 forced_alignment 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 forced_alignment, this is the rule to start with:

forced_alignment Rate-limited

forced_alignment 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.
