Lusha MCP connector

  1. Install the SDK

    Section titled “Install the SDK”
    Terminal window
    npm install @scalekit-sdk/node

    Full SDK reference: Node.js | Python

  2. Set your credentials

    Section titled “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

    Section titled “Set up the connector”

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

    Dashboard setup steps

    Register your Lusha API key with Scalekit so it stores it securely and injects it into every request. Lusha uses API key authentication — there is no redirect URI or OAuth flow.

    1. Get your Lusha API key

      • Sign in to Lusha and go to API & connectors → Manage API Keys.
      • Click + Create new Key to generate a new key, or copy the key value from an existing entry.

      Lusha API Hub showing the Manage API Keys tab with an existing key and a Create new Key button

    2. Create a connection in Scalekit

      • In Scalekit dashboard, go to AgentKit → Connections → Create Connection. Find Lusha MCP and click Create.
      • Note the Connection name — you will use this as connection_name in your code (e.g., lushamcp).
      • Click Save.

    3. Add a connected account

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

      Via dashboard (for testing)

      • Open the connection you created and click the Connected Accounts tab → Add account.
      • Fill in:
        • Your User’s ID — a unique identifier for this user in your system (e.g., user_123)
        • API Key — the Lusha API key from step 1
      • Click Create Account.

      Via API (for production)

      import { Scalekit } from '@scalekit-sdk/node';
      

      const scalekit = new Scalekit(
        process.env.SCALEKIT_ENV_URL,
        process.env.SCALEKIT_CLIENT_ID,
        process.env.SCALEKIT_CLIENT_SECRET,
      );
      

      // Never hard-code credentials — read from secure storage or user input
      const lushaApiKey = getUserLushaApiKey(); // retrieve from your secure store
      

      await scalekit.actions.upsertConnectedAccount({
        connectionName: 'lushamcp',
        identifier: 'user_123',
        credentials: {
          username: lushaApiKey,
        },
      });

  4. Make your first call

    Section titled “Make your first call”
    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 = 'lushamcp'
    const identifier = 'user_123'
    

    // Make your first call
    const result = await actions.executeTool({
      connector,
      identifier,
      toolName: 'lushamcp_contacts_search',
      toolInput: {},
    })
    console.log(result)

What you can do

Section titled “What you can do”

  • Get signals contacts, signals companies — Return recent activity signals (promotions, company changes) for known Lusha contact IDs
  • Filters signals contact, signals company, prospecting contact — Return available contact signal types accepted by contacts signals tools
  • Enrich prospecting contact, prospecting company — Reveal emails and phone numbers for one or more Lusha contact IDs
