MCP

Give your agent fal.ai tools

Every fal.ai 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 fal.ai account for each tool call — you store no tokens.

// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(

API PROXY

Call the fal.ai API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the fal.ai 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.fal.ai/v1/models",
})

// Any allowed fal.ai 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.fal.ai/v1/models

curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9hcGkuZmFsLmFpL3YxL21vZGVscw?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \
  -H "Authorization: Bearer {access_token}" \
  -H "x-pd-environment: production"

SDK

Run fal.ai actions from your backend

Connect a user's fal.ai account once, then run Cancel Request 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: "fal_ai-cancel-request",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    fal_ai: { authProvisionId: "apn_xxxxxxx" },
    appId: "App ID",
    requestId: "Request 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="fal_ai-cancel-request",
    external_user_id="{external_user_id}",  # any stable ID for this user in your system
    configured_props={
        "fal_ai": {"authProvisionId": "apn_xxxxxxx"},
        "appId": "App ID",
        "requestId": "Request ID",
    },
)
