What is the HubSpot Lead Creator MCP Server?
We refused to build a bloated HubSpot integration that requires terrifying OAuth scopes granting access to your entire sales pipeline, financial data, and deal history. Instead, this MCP server provides a surgical, zero-trust bridge: just creating a new Contact.
Your AI agent gains the immediate ability to act as an inbound sales development representative (SDR). During a conversation or when reading an email, if it spots a hot lead, it can instantly dump the name, email, and phone number straight into your HubSpot CRM without human intervention.
The Superpowers
- Automated Data Entry: End manual CRM data entry. The AI parses the context and pushes the lead into HubSpot instantly.
- Zero-Bloat Integration: No massive SDKs. It uses a direct
POSTfetch to the HubSpot/crm/v3/objects/contactsendpoint. You only need a Private App Access Token. - Absolute Containment: Because this is strictly a "Push-only" creation tool, the agent cannot read your CRM, cannot export your customer list, and cannot delete deals. It only drops leads in. A completely secure, one-way funnel.
Built-in capabilities (1)
The "email" field is required. You can also provide firstname, lastname, phone, and company. Creates a new Contact (Lead) directly in HubSpot CRM

Frequently asked questions
Can the agent read my entire customer list in HubSpot?
No. This MCP is strictly unidirectional (Push-only). It only possesses the endpoint to 'Create a Contact'. It cannot read existing contacts or list your database.
What happens if a contact with the same email already exists?
The HubSpot API will return an error (409 Conflict) stating the contact already exists. The AI agent will see this error and know the lead is already in your CRM.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
