# Your HubSpot CRM. In your agent.

Source: https://corespeed.io/integrations/hubspot

Connect HubSpot to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent searches contacts, reads companies and deals, and drafts a follow-up list from what it finds. It uses your own HubSpot account and its permissions. Creating or updating a contact is a separate call that approvals can hold, and deals stay read-only.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect HubSpot after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Know who went quiet. Know who to call

Let your agent search your contacts by stage and last contact, read the ones that matter, and hand back a follow-up list.

You ask your agent: "Find the HubSpot contacts in the Opportunity stage that nobody has contacted in 30 days. Draft a follow-up list. Do not change any records."

It calls CoreSpeed:

- `hubspot__search_contacts`: ok, 455 ms
- `hubspot__get_contact`: ok, 298 ms

It reads from: HubSpot.

### Follow-up list: Six people to call back.

Six contacts in the Opportunity stage have not heard from you in 30 days. Two have gone quiet the longest.

**Call first**

- Jessica at Brightwave: last contacted 34 days ago.
- Dylan at Corvid Labs: last contacted 41 days ago.

**Then**

- The other four: send a short check-in email.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.
2. **Connect HubSpot**: Authorize the account and the content you need.
3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

## Questions

### Can my agent change HubSpot deals?

No. Deals and companies are read-only through CoreSpeed. Contacts can be created or updated, each as a separate call that approvals can hold. How approvals work: https://corespeed.io/docs/approvals

### Do I need a HubSpot private app token?

No. You sign in to HubSpot once through CoreSpeed, and the connection uses that account's access.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
