v0 MCP connector

1. Install the SDK

   Node.js

   npm install @scalekit-sdk/node

   Python

   pip install scalekit

   Full SDK reference: Node.js | Python

2. Set your credentials

   Add your Scalekit credentials to your .env file. Find values in app.scalekit.com > Developers > API Credentials.

   .env

   SCALEKIT_ENVIRONMENT_URL=<your-environment-url>
   SCALEKIT_CLIENT_ID=<your-client-id>
   SCALEKIT_CLIENT_SECRET=<your-client-secret>

3. Set up the connector

   Register your v0 MCP credentials with Scalekit so it can authenticate requests on your behalf. You do this once per environment.

   Dashboard setup steps

   Register your v0 API key with Scalekit so it can authenticate and proxy requests on behalf of your users. v0 MCP uses Bearer Token authentication — there is no redirect URI or OAuth flow.

   1. Get a v0 API key

      • Go to v0.dev and sign in to your account.
      • Click your workspace name in the top-left corner and select Settings.
      • In the left sidebar, click API Keys.
      • Click New Key, give it a name (e.g. Agent Auth), and copy the generated key.

      

   2. Create a connection in Scalekit

      • In the Scalekit dashboard, go to AgentKit → Connections → Create Connection.
      • Search for v0 MCP and click Create.
      • Note the Connection name — use this as connection_name in your code (e.g., v0mcp).

   3. Add a connected account

      Connected accounts link a specific user identifier in your system to a v0 API key. Add them via the dashboard for testing, or via the Scalekit API in production.

      Via dashboard (for testing)

      • Open the connection and click the Connected Accounts tab → Add account.
      • Fill in Your User’s ID and API Key, then click Save.

      Via API (for production)

      Node.js

      await scalekit.connect.upsertConnectedAccount({
        connectionName: 'v0mcp',
        identifier: 'user@example.com',
        credentials: { token: 'your-v0-api-key' },
      })

      Python

      scalekit_client.connect.upsert_connected_account(
          connection_name="v0mcp",
          identifier="user@example.com",
          credentials={"token": "your-v0-api-key"},
      )

4. Make your first call

   Node.js

   quickstart.ts

   import { ScalekitClient } from '@scalekit-sdk/node'
   import 'dotenv/config'
   
   const scalekit = new ScalekitClient(
     process.env.SCALEKIT_ENV_URL,
     process.env.SCALEKIT_CLIENT_ID,
     process.env.SCALEKIT_CLIENT_SECRET,
   )
   const actions = scalekit.actions
   
   const connector = 'v0mcp'
   const identifier = 'user_123'
   
   // Make your first call
   const result = await actions.executeTool({
     connector,
     identifier,
     toolName: 'v0mcp_findchats',
     toolInput: {},
   })
   console.log(result)

   Python

   quickstart.py

   import os
   from scalekit.client import ScalekitClient
   from dotenv import load_dotenv
   load_dotenv()
   
   scalekit_client = ScalekitClient(
       env_url=os.getenv("SCALEKIT_ENV_URL"),
       client_id=os.getenv("SCALEKIT_CLIENT_ID"),
       client_secret=os.getenv("SCALEKIT_CLIENT_SECRET"),
   )
   actions = scalekit_client.actions
   
   connection_name = "v0mcp"
   identifier = "user_123"
   
   # Make your first call
   result = actions.execute_tool(
       tool_input={},
       tool_name="v0mcp_findchats",
       connection_name=connection_name,
       identifier=identifier,
   )
   print(result)
