HubSpot for AI agents

HubSpot is a CRM and marketing platform integrating contacts, deals, email automation, and analytics for sales and marketing teams. Revenue teams rely on it to track customer relationships instead of scattering notes across tools. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

03 · HOW IT WORKS

HubSpot in three steps.

01Your users connect HubSpotThey sign in to HubSpot on Arc0 Connect, under your brand, and approve the access you ask for.
02You set the rulesReads run, writes like “create deal” can wait for the user, and “delete call” can be denied outright.
03Any agent can actYour agent calls HubSpot through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

POLICY.TS

await arc0.policies.set('hubspot', {
  read: 'allow',
  write: 'ask',        // create_deal
  destructive: 'deny',  // delete_call
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \
    https://mcp.arc0.ai/u/u_8f2

04 · AUTH AND DATA

How HubSpot connects.

Users sign in to HubSpot on Arc0 Connect and approve the scopes you request. Build with Arc0’s HubSpot OAuth app, or bring your own so the HubSpot consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same HubSpot connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

HubSpot and Arc0, answered.

Q01

Can I use HubSpot with Claude, ChatGPT or Cursor?

Yes. Connect HubSpot to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the HubSpot actions you allow.

Q02

How do users connect HubSpot?

Q03

Which HubSpot actions can my agent take?

263 in total: 108 read, 96 write and 59 destructive, such as “create deal”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in HubSpot?

Yes. Actions like “delete call” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call HubSpot too?

Yes. The same HubSpot connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
