ElevenLabs

Start RAG indexing of a knowledge base document for an embedding model, or return the current status if an index for that model already exists. Pass the model the agent uses (conversation_config.agent.prompt.rag.embedding_model in the agent's configuration) so the agent can retrieve from the document. Indexing runs in the background; poll the document's RAG indexes until the status is succeeded.

agents_compute_kb_rag_index

Wire an edge between two nodes that already exist on a flow. Unlike creative_add_flow_node's connect_from, which only wires a node as it is created, this repairs or extends the connections on nodes already on the canvas — for example when connect_from could not resolve a port and left the new node unwired.

creative_connect_flow_nodes

Register an MCP server that agents can use as a tool source.

agents_create_mcp_server

Create a brand kit from the colors, typography, rules, voice and workspace media you already know. Gather the brand facts first and create the kit in one call rather than creating an empty kit. A media item (logo, font, document, image, video) references an asset already in the workspace by content_asset_id — from creative_get_available_assets, creative_finalize_asset_upload or creative_attach_reference_file — or a finished generation by generation_id, read off a run's results. A voice item takes a voice_id from creative_list_voices.

creative_create_brand_kit

Build a new brand kit by reading a public website the user named: its logo, colors, typography and tone. Extraction is best-effort and takes a while; use the returned kit as a starting point and refine it with the item tools.

creative_create_brand_kit_from_website

Create an empty flow on the user's canvas and return its flow_id. Call this FIRST whenever the request combines generations — lipsync, a video with a voiceover, anything wiring one output into another — and pass the flow_id to every call that follows, so they all land somewhere they can be connected. Not needed for a single one-off generation.

creative_create_flow

Create a new ElevenLabs Conversational AI agent from a compact set of common fields. Use this for normal agent creation, then refine the result with the agents_update_* tools. API reference: https://elevenlabs.io/docs/api-reference/agents/create

agents_create

Create a new working branch for an ElevenLabs Agent, forked from an existing version. The branch starts as a copy of that version; change its configuration afterwards with the agents_update_* tools, which all take an optional branch_id.

agents_create_branch

Returns an upload_url; send the file's bytes there with a single HTTP PUT whose Content-Type matches mime_type exactly, then call creative_finalize_asset_upload with the returned asset_id. Never read the file into the conversation. The URL is short-lived and accepts only this one object at this exact size and type. origin is set by the view, never by the model.

creative_create_asset_upload

Create a code tool: runs custom JavaScript in a sandboxed environment, for logic a webhook can't express. Requires an Enterprise workspace plan -- the underlying API call fails with a 'code tools are not enabled' error otherwise. Docs: https://elevenlabs.io/docs/eleven-agents/customization/tools/code-tools

agents_create_code_tool

Raise a ticket about an agent's performance on a conversation, for triage with Architect. Provide an overall comment and/or turn-level comments describing what went wrong.

agents_create_triage_ticket

Create a draft for an ElevenLabs Agent.

agents_create_draft

Generate an image from a text prompt. This is the tool for any request to create an image. Returns at once with flow_id, node_id and session_ids, plus a url the user can open to keep editing on the canvas. If a view renders it tracks progress on its own; otherwise poll creative_get_flow_run_status with the flow_id and session_ids until all_completed or has_failures is true. Pass that flow_id back to add to the same flow; omit it and a flow is created. If this generation will feed another (lipsync, a voiceover), call creative_create_flow first and pass that flow_id here and to every related call — nodes on different flows cannot be connected. Spends credits: pass estimate_only to price a run before committing to it, and never call this a second time to retry — that starts and charges a second generation.

creative_generate_image

Create a knowledge base document from a URL.

agents_create_kb_url

Create a folder in the knowledge base.

agents_create_kb_folder

Create a knowledge base document from raw text.

agents_create_kb_text

Manually raise a follow-up ticket against an agent, not tied to any conversation (for example a task like 'add the KB about X').

agents_create_manual_triage_ticket

Open a merge proposal asking to merge a source branch into a target branch, for someone with write access to the target to review and merge.

agents_create_merge_proposal

Create or update the live traffic split across an ElevenLabs Agent's branches. Each call replaces the whole split, so include every branch that should keep traffic; percentages must total 100.

agents_create_deployment

Create a procedure on an agent branch. A procedure is a standard operating procedure the agent follows for one specific task: trigger says when the agent should use it, content says what to do. There are two types. A free-form procedure (type=free_form) is markdown instructions that are injected into the prompt when the procedure is active; the agent reads them and uses judgment about wording and order. A structured procedure (type=deterministic) is a list of typed steps the agent runs in a fixed order, every time. Set trigger as the top-level field; never write it inside content. For structured content, send the steps object JSON-encoded in content; its shape and rules are documented at https://elevenlabs.io/docs/eleven-agents/customization/procedures/structured-procedures. The procedure is a draft until the agent is published; saving the draft (agents_create_draft) and publishing both validate structured procedures and return per-procedure errors with the path of each offending step.

agents_create_procedure

Generate speech from a text prompt. This is the tool for any request to create speech. Returns at once with flow_id, node_id and session_ids, plus a url the user can open to keep editing on the canvas. If a view renders it tracks progress on its own; otherwise poll creative_get_flow_run_status with the flow_id and session_ids until all_completed or has_failures is true. Pass that flow_id back to add to the same flow; omit it and a flow is created. If this generation will feed another (lipsync, a voiceover), call creative_create_flow first and pass that flow_id here and to every related call — nodes on different flows cannot be connected. Spends credits: pass estimate_only to price a run before committing to it, and never call this a second time to retry — that starts and charges a second generation.

creative_generate_speech

Transcribe speech in an audio file into text. This is the tool for any request to transcribe, caption or "what does this audio say". Pass connect_from with the audio node already on the flow and it starts at once; omit it and a picker is shown to the user that lets them record from their microphone or pick a local file, then uploads the audio and starts the transcription itself. Returns flow_id, node_id and session_ids, plus a url the user can open to keep editing on the canvas. If a view renders it tracks progress on its own; otherwise poll creative_get_flow_run_status until all_completed or has_failures is true — the transcript comes back in `transcripts`, each with per-word start/end seconds in `words` for captions and subtitles, plus `words_download_url` for the full list. Pass flow_id back to stay on the same flow. Do not call this a second time to retry; that starts and charges a second transcription.

creative_transcribe_audio

Create an agent response test.

agents_create_test

Create a folder for organizing agent tests, optionally inside parent_folder_id.

agents_create_test_folder

Create an ElevenLabs Agent tool (client, webhook, or other type per the request body).

agents_create_tool

Generate a video from a text prompt. This is the tool for any request to create a video. Returns at once with flow_id, node_id and session_ids, plus a url the user can open to keep editing on the canvas. If a view renders it tracks progress on its own; otherwise poll creative_get_flow_run_status with the flow_id and session_ids until all_completed or has_failures is true. Pass that flow_id back to add to the same flow; omit it and a flow is created. If this generation will feed another (lipsync, a voiceover), call creative_create_flow first and pass that flow_id here and to every related call — nodes on different flows cannot be connected. Spends credits: pass estimate_only to price a run before committing to it, and never call this a second time to retry — that starts and charges a second generation.

creative_generate_video

Delete a registered MCP server.

agents_delete_mcp_server

Delete a whole brand kit. Use creative_delete_brand_kit_item instead when the user only wants one item removed. This cannot be undone, so confirm with the user first.

creative_delete_brand_kit

Remove one item from a brand kit while leaving the rest in place.

creative_delete_brand_kit_item

Permanently delete an ElevenLabs Agent together with all of its conversations. This cannot be undone. To hide an agent while keeping it and its history, archive it instead with agents_update_operations, passing archived: true.

agents_delete

Delete a conversation triage ticket. Restricted to the ticket creator or a workspace admin.

agents_delete_triage_ticket

Delete the draft of an ElevenLabs Agent.

agents_delete_draft

Delete nodes from a flow, along with every edge into or out of them. The batch is all or nothing. Their past generations stay in the user's history. Only delete nodes the user asked to remove.

creative_delete_flow_nodes

Delete a knowledge base document.

agents_delete_kb_document

Delete a phone number from the workspace.

agents_delete_phone_number

Remove a procedure from an agent branch.

agents_delete_procedure

Delete the draft of a procedure on an agent branch.

agents_delete_procedure_draft

Delete an agent response test.

agents_delete_test

Delete an ElevenLabs Agent tool.

agents_delete_tool

Design a brand-new voice from a text description. Not for picking a voice that already exists — use creative_list_voices for that. Needs two things from the user, never invented or auto-generated: the actual line the previews will speak (text, 100-1000 characters) and its language. Returns three previews to choose between — the result renders a picker; once the user picks one, call creative_save_designed_voice with its generated_voice_id to keep it in the workspace's voice library. The rendered view lets the user edit the line themselves and regenerate; view_state_id is how it does that and is never something you should set. Spends credits: never call this a second time to retry — that generates and charges for three more previews.
