MCP

Give your agent Vapi tools

Every Vapi action is exposed as an MCP tool on Pipedream's remote server. Point a client at it with your end user's ID and Connect resolves that user's Vapi account for each tool call — you store no tokens.

Pipedream Connect

// 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": "vapi",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// e.g. run Create Call:
const result = await mcp.callTool({
  name: "vapi-create-call",
  arguments: {
    name: "Conversation Name",
    assistantId: "Assistant ID",

# access_token: mint a short-lived token with the Connect SDK — see the MCP guide

API PROXY

Call the Vapi API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the Vapi API with the connected user's credentials attached. You store no tokens and write no refresh logic.

Pipedream Connect

const resp = await pd.proxy.get({
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  accountId: "apn_xxxxxxx",
  url: "https://api.vapi.ai/call",
})

// Any allowed Vapi endpoint works here. Pipedream attaches the
// connected account's credentials to the outgoing request.

# The path segment is the target URL, URL-safe base64 encoded:
# https://api.vapi.ai/call

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9hcGkudmFwaS5haS9jYWxs?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"

SDK

Run Vapi actions from your backend

Connect a user's Vapi account once, then run Create Call on their behalf from your own code — TypeScript, Python, or plain HTTP.

Pipedream Connect

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 result = await pd.actions.run({
  id: "vapi-create-call",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    vapi: { authProvisionId: "apn_xxxxxxx" },
    name: "Conversation Name",
    assistantId: "Assistant ID",
  },
})

from pipedream import Pipedream

pd = Pipedream(
    client_id="{oauth_client_id}",
    client_secret="{oauth_client_secret}",
    project_id="{project_id}",
    project_environment="production",
)

result = pd.actions.run(
    id="vapi-create-call",
    external_user_id="{external_user_id}",  # any stable ID for this user in your system
    configured_props={
        "vapi": {"authProvisionId": "apn_xxxxxxx"},
        "name": "Conversation Name",
        "assistantId": "Assistant ID",
    },
)

curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
  -H "Content-Type: application/json" \
  -H "X-PD-Environment: production" \
  -H "Authorization: Bearer {access_token}" \
  -d '{
    "external_user_id": "{external_user_id}",
    "id": "vapi-create-call",
    "configured_props": {
      "vapi": { "authProvisionId": "apn_xxxxxxx" },
      "name": "Conversation Name",
      "assistantId": "Assistant ID"
    }
  }'
