Values you fill in

  • Authorization secret HTTP header
    Bearer token from Compeller Account → API Access, POST /api/login, or POST /api/v1/auth/token. Discovery tools work without this header; generation/account tools require it.
  • X-API-Token secret HTTP header
    Alternative Compeller API token header. Use this instead of Authorization if your MCP client stores token values without the Bearer prefix.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • get_capabilities

    Get Compeller platform capabilities, supported features, and API version.

  • get_pricing

    Get current Compeller subscription plans and pricing.

  • list_styles

    List available visual styles for Compeller video generation.

  • upload_media

    Get upload instructions for media files (audio, images, video). Returns the upload URL and required headers. Requires API token authentication.

  • search_music

    Search Deezer preview tracks by song, artist, or album. Use this when the user provides a song string but no MP3/WAV/FLAC file.

  • create_compel_from_music

    Create a compel from a selected Deezer preview track. If the user provides an audio file instead, upload that file and use create_compel.

  • create_compel

    Create a Compeller generation job from primary audio media and optional reference media. Returns compel id, status, and links to track progress and retrieve renderings.

  • get_compel

    Get the current status, progress, and details of a Compeller generation job.

  • start_render

    Start rendering a READY compel with default configuration so an agent can continue to final MP4 without opening the browser UI.

  • list_compels

    List all Compeller generation jobs for the authenticated account, newest first.

  • search_compels

    Search Compeller generation jobs by title for the authenticated account.

  • list_renderings

    List all video renderings for a specific compel.

  • get_rendering

    Get details of a specific video rendering.

  • search_media

    Search and list uploaded media files for the authenticated account.

  • register_webhook

    Register an HTTPS endpoint to receive signed push notifications for compel lifecycle events (compel.ready when renderable, compel.completed, compel.failed). Returns webhook_id and the HMAC-SHA256 signing secret exactly once - store the secret immediately, it is never returned aga

  • list_webhooks

    List all webhook endpoints registered for the authenticated account. Secrets are never returned by this tool.

  • delete_webhook

    Delete a webhook endpoint by id. Removes the registration and stops future deliveries.

  • test_webhook_delivery

    Synchronously POST a synthetic webhook.test event to a registered endpoint. Uses the same HMAC-SHA256 signature as real deliveries, runs the standard URL safety check at delivery time, and returns {webhook_id, event_id, event_type, delivered, response_status, response_body_previe

  • update_webhook

    Update one or more mutable fields on a registered webhook endpoint: url, events, active. At least one of these must be provided. Validation mirrors register_webhook (https-only, <= 2048 chars, URL safety blocklist). Returns the updated endpoint (secret is never returned by this t

  • rotate_webhook_secret

    Mint a new HMAC-SHA256 signing secret for a registered webhook endpoint. The previous secret is invalidated immediately - integrators must update their receiver before the next compel terminal event fires. Returns the new secret exactly once; store it on receipt.

  • cancel_compel

    Cancel an in-progress compel. Dequeues it if still queued, otherwise cancels any active external (AI provider) tasks and transitions it to CANCELLED. Idempotent - cancelling an already-CANCELLED compel succeeds. Use to stop a mis-prompted or runaway job before it consumes more re

  • get_account_credits

    Get the authenticated account's render-minute balance and plan: minutes remaining (free + paid), monthly allowance, plan code, and whether the quota is exceeded. Call before starting an expensive render so an agent can make cost-aware decisions.

  • list_lighting_effects

    List the COM-497 starter lighting effects available to launch as cues (e.g. "gobo-cycle", "x-move", "dimmer-pulse"). Each effect carries an id, the capabilities it needs, and a launch_contract template. Use the returned id as effect_id for launch_lighting_cue.

  • launch_lighting_cue

    Launch a starter lighting effect onto a stage as a live cue (e.g. "gobo-cycle on the stage's 7R beams at speed 0.5"). Pass effect_id (from list_lighting_effects) and optional variables to override effect defaults. Validation is loud: an unknown effect, a launch_contract whose bin

  • list_lighting_cues

    List the live (non-stopped) lighting cues REACT is executing, including each cue's launch_id, resolved variables, launch_contract, and feedback. Optionally scope to one stage.

  • get_lighting_cue

    Fetch a single live lighting cue by its launch_id, including resolved variables, launch_contract, and REACT feedback.

  • stop_lighting_cue

    Stop a live cue by its launch_id. Idempotent - the cue is marked stop-requested so REACT drops it on its next refresh.

  • set_lighting_cue_variables

    Update variables on a live cue (e.g. change cycle speed or intensity mid-show). Only the variables you pass change; the rest keep their current values. Stopped cues are rejected.

  • ack_lighting_cue

    REACT/BAE acknowledgement for a launch_id. Idempotently records whether the executor accepted or rejected the cue and which executor observed it.

  • report_lighting_cue

    REACT/BAE report-back for cue status, active variables, skipped bindings, capability misses, last_frame_at, and errors.

Common questions

Is Compeller safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization, X-API-Token

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 6 months ago, and the latest version (0.5.1) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Compeller MCP

Public documentation and metadata for the hosted Compeller MCP server.

Compeller turns music into performance-ready visuals. Agents can discover styles and pricing, search for music, create and track Compels, start renders, retrieve finished videos, and register signed webhooks for completion events.

This repository contains public connector documentation and metadata only. The production Compeller application source code is not published here.

Remote MCP endpoint

https://compeller.ai/api/mcp

Quick config

Most MCP clients that support remote Streamable HTTP servers can use:

{

"mcpServers": { "compeller": { "url": "https://compeller.ai/api/mcp", "headers": { "Authorization": "Bearer YOUR_COMPELLER_API_TOKEN" } } } }

If your MCP client stores raw token values without the Bearer prefix, use the alternate header:

{

"mcpServers": { "compeller": { "url": "https://compeller.ai/api/mcp", "headers": { "X-API-Token": "YOUR_COMPELLER_API_TOKEN" } } } }

Discovery works without authentication. Generation, account, media, rendering, and webhook tools require a Compeller API token.
