What an agent can do here

Official hosted MCP server with read/write access to contacts, companies, deals, tickets and engagements — free on every HubSpot tier, including the free CRM.

Action depth
Core write

Agents can do the product’s core job — edit the timeline, ship the deploy, update the record.

Hosting
Vendor-hosted

Connect with a URL — nothing to install.

Auth
OAuth
Unattended
Needs a human

Interactive OAuth only — it cannot be provisioned without someone clicking through.

Blast radius
High

A wrong call is expensive, public, or irreversible.

Permission scoping: Granular scopes

What it costs to let an agent act

FreeUnmetered

Free on every tier including the free CRM; marketing data is read-only.
