Task

MCP Tool

Fallback (Direct API)

Generate video from prompt

mcp__heygen__generate_video_agent

POST /v3/video-agents

Check video status / get URL

mcp__heygen__get_video

GET /v3/videos/{video_id}

List account videos

mcp__heygen__list_videos

GET /v3/videos

Delete a video

mcp__heygen__delete_video

DELETE /v3/videos/{video_id}

If no HeyGen MCP tools are available, use direct HTTP API calls as documented in the reference files.

Default Workflow

Always use prompt-optimizer.md guidelines to structure prompts with scenes, timing, and visual styles.

With MCP tools:

• Write an optimized prompt using prompt-optimizer.md → visual-styles.md

• Call mcp__heygen__generate_video_agent with prompt and config (duration_sec, orientation, avatar_id)

• Call mcp__heygen__get_video with the returned video_id to poll status and get the download URL

Without MCP tools (direct API):

• Write an optimized prompt using prompt-optimizer.md → visual-styles.md

• POST /v3/video-agents — see video-agent.md

• GET /v3/videos/<id> — see video-status.md

Reference Files

Read these as needed — they contain endpoint details, request/response schemas, and code examples (curl, TypeScript, Python).

Core workflow:

• references/prompt-optimizer.md — Writing effective prompts (scenes, timing, visual styles)

• references/visual-styles.md — 20 named visual styles with full specs

• references/prompt-examples.md — Production prompt examples and templates

• references/video-agent.md — POST /v3/video-agents request fields, response format, file inputs

Foundation:

• references/video-status.md — GET /v3/videos/{id} polling and download

• references/webhooks.md — Webhook endpoints and events

• references/assets.md — Uploading images, videos, audio as references

• references/dimensions.md — Resolution and aspect ratios

• references/quota.md — Credit system and usage limits

Best Practices

• Optimize your prompt — quality depends entirely on prompt structure. Always use the prompt optimizer

• Lock avatar if needed — pass avatar_id for consistency across videos

• Specify voice — pass voice_id for a specific narrator voice

• Upload reference files — help the agent understand your brand/product

• Iterate on prompts — refine based on results; Video Agent is great for quick iterations
