HubSpot MCP connects HubSpot’s hosted MCP (Model Context Protocol) server to Cargo so AI agents can call HubSpot’s tools directly. It is separate from the regular HubSpot CRM connection: it authorizes against HubSpot’s MCP server, not the CRM API.

​
How to set up HubSpot MCP

​
Authentication

HubSpot MCP uses OAuth authorization:
  1. Create a HubSpot MCP connector in Cargo
  2. Click Authorize HubSpot MCP
  3. Sign in to HubSpot in the popup and grant access
  4. Cargo stores the resulting token and refreshes it automatically
Code slugs — integration slug: hubspotMcp. This integration exposes no fixed actions: its tools are discovered from HubSpot’s MCP server at runtime and made available to agents.

​
HubSpot MCP tools

The connector does not define static actions. When attached to an agent as an MCP server, the agent lists the tools HubSpot’s server advertises at runtime and can call any of them. See MCP servers for how agents use MCP tools. Related MCP integrations: Salesforce MCP and Notion MCP.

Best practices

  • Use HubSpot MCP for agent tool use; keep the regular HubSpot connector for workflow actions and data syncing
  • Authorize with a HubSpot user whose permissions match what you want agents to be able to do
  • Re-authorize the connector if HubSpot access is revoked on the HubSpot side
