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.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
