HubSpot for your AI agent

Give Claude Code, Cursor, Codex or your own agent HubSpot through one MCP URL and one key. Your team signs in to HubSpot once and the agent never holds a token. Reads run at once; anything that changes HubSpot waits for your approval.

Cursor · ~/.cursor/mcp.json (or .cursor/mcp.json in a project)

{
  "mcpServers": {
    "vellarin": {
      "url": "https://hub.vellarin.ai/api/hub/mcp",
      "headers": {
        "Authorization": "Bearer ${env:VELLARIN_HUB_KEY}"

Questions

HubSpot and AI agents

How do I connect HubSpot to Claude Code, Cursor or Codex?

Create a free Vellarin account, connect HubSpot with its normal sign-in, create an agent key on the Developers page and add the Vellarin Hub MCP server to your client with one line. Your agent then sees the HubSpot actions as tools.

Can my agent change things in HubSpot without asking me?

No. Read actions run at once. Any action that sends, creates, changes or deletes something in HubSpot waits for the workspace owner's approval and then runs exactly once.

Does my agent get my HubSpot password or token?

No. The sign-in lives on the server side. Your agent holds only a Vellarin Hub key, which you can scope to HubSpot alone, cap per day and per month, and revoke at any moment.

What does it cost?

Hub Free includes 500 app calls a month and 1 agent key, with no card. Over the cap the answer is "upgrade or wait", never a charge.
