HubSpot MCP Server

A Model Context Protocol (MCP) server that provides AI assistants (Claude, Cursor, etc.) with a comprehensive interface to the HubSpot CRM API. Supports both static access tokens and OAuth2 authentication.

Overview

hubspot-mcp allows your AI assistant to directly interact with your HubSpot CRM data. It enables powerful natural language queries like:

• "Search for contacts at 'Acme Corp'."
• "Show me all open deals worth over $10,000."
• "List the most recently created companies."
• "Get the details of contact [email protected]."

Features

• OAuth2 Support: Browser-based OAuth flow with automatic token refresh, powered by @vineethnkrishnan/oauth-core.
• Static Token Support: Use a HubSpot private app access token for simple setups.
• Modular Architecture: Built with clean layered design for high maintainability.
• Type-Safe: Fully implemented in TypeScript with Zod schema validation.
• Comprehensive Coverage: Full access to Contacts, Deals, and Companies.

Installation

Using npx (Recommended)

No installation required. Run directly:

npx -y @vineethnkrishnan/hubspot-mcp

Global Install

npm install -g @vineethnkrishnan/hubspot-mcp
hubspot-mcp

From Source

git clone https://github.com/vineethkrishnan/mcp-pool.git
cd mcp-pool
npm install
npm run build

Configuration

To use this server with an MCP client like Claude Desktop, add to your MCP client configuration file:

| Platform | Config file path | |----------|-----------------| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json | | Linux | ~/.config/Claude/claude_desktop_config.json |

Using a Static Access Token

{
  "mcpServers": {
    "hubspot": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/hubspot-mcp"],
      "env": {
        "HUBSPOT_ACCESS_TOKEN": "pat-na1-..."
      }
    }
  }
}

Using OAuth2

{
  "mcpServers": {
    "hubspot": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/hubspot-mcp"],
      "env": {
        "HUBSPOT_CLIENT_ID": "abc12345-...",
        "HUBSPOT_CLIENT_SECRET": "secret_abc12345..."
      }
    }
  }
}

Then run the OAuth setup:

hubspot-mcp auth login

This will:

1. Open a browser window where you'll log in to HubSpot and authorize the app
2. After you approve, the browser will show a success message
3. Your tokens are saved locally at ~/.mcp-pool/hubspot/ and refresh automatically

Environment Variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | HUBSPOT_ACCESS_TOKEN | No* | - | Static HubSpot private app access token. | | HUBSPOT_CLIENT_ID | No* | - | OAuth2 client ID. | | HUBSPOT_CLIENT_SECRET | No* | - | OAuth2 client secret. |

*Either HUBSPOT_ACCESS_TOKEN or both HUBSPOT_CLIENT_ID and HUBSPOT_CLIENT_SECRET must be provided.
