MCP
One MCP session, both toolsets
One session gives your product or agent every HeyGen and Slack tool at once — connect once, list tools, and call them like any single-app session.
// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,
"x-pd-project-id": "{project_id}",
"x-pd-environment": "production",
"x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
"x-pd-app-slug": "heygen,slack_v2",
},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// One list, both toolsets: HeyGen and Slack tools arrive
// together, each keyed by its own app's slug.
// e.g. run List Avatar Look ID Options:
const result = await mcp.callTool({
name: "heygen-list-avatar-look-id-options",
arguments: {
avatarType: "Avatar Type",
ownership: "Ownership",
},
})import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const externalUserId = "{external_user_id}" // any stable ID for this user in your system
const [heygenTools, slackV2Tools] =
await Promise.all([
pd.components.list({ app: "heygen" }),
pd.components.list({ app: "slack_v2" }),
])
// One external user owns both connected accounts, so either app's tools
// run on their behalf with the same externalUserId.curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=heygen" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}"
curl "https://api.pipedream.com/v1/connect/{project_id}/components?app=slack_v2" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}"
# Connect both accounts to the same external_user_id, then
# configure and invoke either app's tools on that user's behalf.ARCHITECTURE
One user, two connected accounts
Your user connects each account once, under whatever ID they already have in your product. The two stay independent — either can be revoked on its own — and your code reaches both through that one user.

Actions
-
List Avatar Look ID Options
actionRetrieves a page of available avatar looks, whoseidcan be used for Avatar Look ID fields. Listsphoto_avatarlooks by default; set Avatar Type todigital_twinorstudio_avatarfor other kinds, and Ownership topublicorprivateto narrow further. Pass Fields to keep the response small. Ifhas_moreis true, passnext_tokenas the Token to get the next page. Example: Limit2and Fields["id", "name"]returns{"data": [{"id": "look_1", "name": "Office look"}, {"id": "look_2", "name": "Outdoor look"}], "has_more": true, "next_token": "abc"}. See the documentationRead-onlyv0.0.1 -
List Custom Events Options
actionRetrieves all available webhook event types, whoseevent_typecan be used for Custom Events fields. The full list is returned in a single response (no paging). Example: returns{"data": [{"event_type": "avatar_video.success", "description": "Fires when an avatar video finishes"}]}. See the documentationRead-onlyv1.0.0 -
List Template ID Options
actionRetrieves a page of available templates, whoseidcan be used for Template ID fields. Ifhas_moreis true, passnext_tokenas the Token to get the next page. Example: Limit2returns{"data": [{"id": "tpl_1", "name": "Product launch", "aspect_ratio": "16:9"}, {"id": "tpl_2", "name": "Weekly update", "aspect_ratio": "9:16"}], "has_more": true, "next_token": "abc"}. See the documentationRead-onlyv1.0.0 -
List Videos
actionRetrieves a page of videos, newest first, with theirid,status, and download links once completed. Use this to find a video ID for other actions. Note: the HeyGen v3 list may not include videos created in the HeyGen web app (it can return an empty list even when such videos exist); if you already know a video's ID, use Retrieve Video Link instead, which works for any video ID. Pass Fields to keep the response small. Ifhas_moreis true, passnext_tokenas the Token to get the next page. Example: TitleOnboardingwith Limit2and Fields["id", "title", "status"]returns{"data": [{"id": "v_123", "title": "Onboarding intro", "status": "completed"}, {"id": "v_122", "title": "Onboarding part 2", "status": "processing"}], "has_more": true, "next_token": "abc"}. See the documentationRead-onlyv0.0.1 -
List Voice ID Options
actionRetrieves a page of available voices, whosevoice_idcan be used for Voice ID fields. Lists public voices by default; set Voice Type toprivateto list your own cloned voices, and use Language and Gender to narrow results instead of paging through every voice. Ifhas_moreis true, passnext_tokenas the Token to get the next page. Example: LanguageSpanish, Genderfemaleand Limit2returns{"data": [{"voice_id": "voice_1", "name": "Camila", "language": "Spanish", "gender": "female"}, {"voice_id": "voice_2", "name": "Lucia", "language": "Spanish", "gender": "female"}], "has_more": true, "next_token": "abc"}. See the documentationRead-onlyv1.0.0 -
Retrieve Video Link
actionFetches a link for a specific heygen video. The link is only available once the video status iscompleted. Works for any video ID, including videos created in the HeyGen web app. If you don't have the video ID, use the List Videos action first (note it may not list web-app videos). Example: Video IDv_123returns{"data": {"id": "v_123", "status": "completed", "video_url": "https://..."}, "video_link": "https://..."}; while the video is still processing,video_linkis null anddata.statusisprocessing(check again later). If generation failed,data.statusisfailed,video_linkis null, andfailure_codeandfailure_messageexplain why; the video will never complete, so do not keep polling. See the documentationRead-onlyv1.0.0

Send Message to Channel
actionSend a message to a public or private channel. Legacy, channel-only variant — prefer Post Message for new integrations: it covers channels, users, and groups from a single tool, and also supports threaded replies and unfurl settings. Use this tool only if a workflow specifically needs to target a channel exclusively, without the user/group support Post Message offers. See the documentationWritev0.3.2 -
Add Emoji Reaction
actionAdd an emoji reaction to a message. See the documentationWritev0.0.34 -
Add Reaction
actionAdd an emoji reaction to a message. Accepts a channel ID (preferred — resolves instantly) or channel name (resolved by scanning up to 5 pages, ~5,000 channels, of the workspace's channel list — a name beyond that bound will not be found). Use Get Channel History or Search to find the message timestamp. Emoji name should be without colons (e.g.thumbsup,fire,heart). See the documentationWritev0.0.14 -
Archive Channel
actionArchive a public or private channel. Direct messages and group DMs can't be archived — pass a channel ID (e.g.C1234567890), not a user or group ID. See the documentationWritev0.0.42 -
Browse Files
actionList files shared in a channel or across the workspace. Accepts a channel ID (preferred — resolves instantly) or channel name (resolved by scanning up to 5 pages, ~5,000 channels, of the workspace's channel list — a name beyond that bound will not be found). Filter by file type (e.g.images,pdfs,snippets). Returns file metadata including name, type, size, and download URL. See the documentationWritev0.0.15 -
Build and Send a Block Kit Message
actionConfigure custom blocks and send to a channel, group, or user. For plain-text or standard messages, prefer Post Message — it posts as the authenticated user by default (noPipedream:bot prefix on notifications) and accepts Block Kit blocks too. Use this tool when you specifically want the guided Block Kit builder. See the documentation.Writev1.0.2 -
Create a Channel
actionCreate a new channel. See the documentationWritev0.0.42 -
Create Reminder
actionCreate a reminder. See the documentationWritev0.0.43
