HeyGen through One

HeyGen is an AI video generation platform that enables users to create, translate, and personalize high-quality videos using realistic AI avatars and voiceovers, allowing businesses and creators to produce scalable video content from text without cameras or editing expertise.

One exposes HeyGen through four MCP tools. The table below carries real action ids from One's knowledge base, so for a common operation you can skip search and go straight to reading the action's parameters.

How to run an action

1. Find the action in the table below, or call search_one_platform_actions with platform hey-gen if it is not listed.
2. Call get_one_action_knowledge with the action id. Do this every time, including for actions in this table. The table gives you the id, not the parameters.
3. Call execute_one_action with parameters copied from that knowledge.

Never guess a parameter name, a body field, or an enum value. The knowledge has the real schema, and a guessed field is either a 400 or a silent write of the wrong thing.

Before you start

Call list_one_integrations once and confirm HeyGen is connected. If it is missing, the user has not connected it: say so and point them at https://app.withone.ai rather than reaching for raw HTTP.

Each connection carries an field. If it reports the agent is read-only here, so plan a read-only answer instead of attempting a write that will be refused.
