API and MCP
Ask your AI agent for the video.
heyCreatr was built API-first. Every button in the app is an API call, and the MCP server hands the same calls to an AI agent, so an assistant like Claude can write the story, generate the scenes, render and hand you the link.
MCP server
Tools for projects, Guide steps, images, videos, voices, music, versions, characters, footage, swaps, renders and jobs. Each tool says where its ids come from.
Sign in with your login
Connect the claude.ai connector and approve it with your heyCreatr login. No static token to paste. Revoke it any time under Settings.
REST API
An OpenAPI 3.1 document, API keys as Bearer tokens, and generation calls that return a job straight away.
Know when it's done
Follow a job by polling, over the event stream, or by webhook.
Signed webhooks
Job, render, swap and performance events, signed with HMAC-SHA256, retried five times with growing gaps, every attempt logged.
A project brief
One MCP resource summarises a whole project in a single read, so an agent knows where things stand before it acts.
What an agent run looks like
- Create a project from a brief.
- Run the Guide's story step and wait on the job.
- Run characters, images, voiceovers and videos the same way.
- Render, wait, and return the MP4 and share link.
Every step runs on your own provider keys and shows up in Usage & costs like anything you did by hand.
Same price, API included
The API, the MCP server and webhooks are part of the 39 EUR plan.
