Concrete capability record

Data, retrieval, actions, identity, and operating limits

A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.

01 · Records and state owned

Generate scripted avatar videos, translate clips, run lip-sync workflows, select account avatars and voices, and render or deliver media through natural-language requests

02 · Data you can retrieve

Generate scripted avatar videos, translate clips, run lip-sync workflows, select account avatars and voices, and render or deliver media through natural-language requests

03 · Actions and write paths

The targeted review confirmed this HeyGen capability surface: Generate scripted avatar videos, translate clips, run lip-sync workflows, select account avatars and voices, and render or deliver media through natural-language requests. It did not normalize every mutation tool. Treat writes as unapproved until each current tool, scope, plan and approval behavior is verified.

04 · Authentication and permissions

Official HeyGen documentation confirms a hosted OAuth endpoint with no local server or API-key setup. Existing vendor identity, account, tenant, and permission controls should be treated as the authorization boundary.

05 · Monitoring, approval, and recovery

Official HeyGen documentation confirms a hosted OAuth endpoint with no local server or API-key setup. Official HeyGen documentation confirms a hosted OAuth endpoint with no local server or API-key setup. Operations consume existing plan credits and depend on Video Agent availability; generated media should be reviewed before external distribution.

06 · Gaps and implementation limits

Official HeyGen documentation confirms a hosted OAuth endpoint with no local server or API-key setup. Operations consume existing plan credits and depend on Video Agent availability; generated media should be reviewed before external distribution.

First-party MCP tool catalog

46 named MCP tools · HeyGen-hosted MCP server

The exact named tools published for HeyGen's hosted OAuth MCP server at mcp.heygen.com/mcp/v1/. Reviewed Jul 10, 2026. The server is available across HeyGen plans and consumes the connected account's included or premium credits. Generation and training can be asynchronous. Media generation, voice cloning, avatar creation, and permanent deletion are consequential; custom agent domains must be allowlisted.
