Can I use HeyGen as a CLI?

Yes. KosmoKrator exposes a HeyGen CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose HeyGen through MCP?

Yes. The KosmoKrator MCP gateway can expose selected HeyGen tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are HeyGen credentials stored?

HeyGen credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for HeyGen MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

HeyGen CLI for Coding Agents

Use the HeyGen CLI for coding agents with headless JSON commands, schema discovery, credentials, and permission controls.

HeyGen CLI for Coding Agents

Let coding agents discover schemas and execute integration functions through CLI commands or MCP.

Use this pattern when another coding agent needs exact commands and schema discovery. The HeyGen CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# HeyGen CLI for Coding Agents
kosmokrator integrations:configure heygen --set access_token="$HEYGEN_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call heygen.heygen_list_videos '{"limit":1,"offset":1}' --json

Discovery Before Execution

Agents and scripts can inspect HeyGen docs and schemas before choosing a function.

kosmo integrations:docs heygen --json
kosmo integrations:docs heygen.heygen_list_videos --json
kosmo integrations:schema heygen.heygen_list_videos --json
kosmo integrations:search "HeyGen" --json
kosmo integrations:list --json

Useful HeyGen CLI Functions

Function	Type	Parameters	Description
`heygen.heygen_list_videos`	Read	limit, offset	List generated videos from HeyGen. Returns video IDs, statuses, and metadata. Use limit and offset for pagination.

`heygen.heygen_create_video`	Write	video_inputs, dimension, test	Generate a new AI video on HeyGen. Provide video_inputs defining scenes (avatar, voice, script), optional dimensions, and test mode. Returns a video_id to track generation progress.
`heygen.heygen_list_avatars`	Read	none	List all available talking avatars from HeyGen. Returns avatar IDs, names, preview images, and supported styles. Use avatar IDs when creating videos.
`heygen.heygen_list_voices`	Read	none	List all available voices from HeyGen. Returns voice IDs, display names, supported languages, gender, and preview audio URLs. Use voice IDs when creating videos.

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
