Connect HubSpot to Claude, ChatGPT, and any MCP client

Everything to know before connecting HubSpot to Claude, ChatGPT, or any MCP client: the buildability verdict, the proposed tools, and the guardrails.

Every system here gets an honest, affirmative path: verified and instant, buildable and provisioned, human-assisted, or a done-for-you conversation. Zero dead ends.

Where HubSpot stands today

Verified. Connect now.Instant deploy

173 tools from HubSpot's API, a core surface built from the vendor's own spec. Among the systems people most want connected, HubSpot earned a hand-tuned mapping. megamcp maintains it, so intake ends with a working connector URL in minutes.

From our index notes on HubSpot: REST API with granular OAuth scopes; rate limits and some endpoints vary by subscription tier.

Pipelines, contacts, deals, and activity history: the context an assistant needs at hand when you ask about your book of business.

Also searched as hub spot, hubspot crm. The vendor's developer documentation lives at developers.hubspot.com. A machine-readable OpenAPI description is on file.

Proposed tools

What a HubSpot connector would expose

The proposal you review during intake, separated into Read and Write. Nothing writes without asking you first.

Built from OpenAPI spec

Generated from the published machine-readable spec, then run through validation gates before going live. The list shown here is a representative preview; the real spec build produces the full tool list.

Readon by default
  • search_contacts

    Find contacts by name, email, company, or owner

  • get_contact

    Fetch one contact with its full field set

  • list_deals

    List deals filtered by stage, owner, or close date

  • list_activities

    List calls, emails, and notes on a record

Writeon, asks first
  • create_contactconfirm

    Create a new contact record

    fields: name, email, phone, company

  • update_deal_stageconfirm

    Move a deal to another pipeline stage

    fields: stage, probability

  • add_noteconfirm

    Attach a note to a contact or deal

    fields: body

  • delete_contactdestructivedry-run

    Permanently delete a contact record

    fields: id

Every write asks first: it pauses on a preview of the exact change and runs only when you approve it, before anything reaches HubSpot. Turn off anything you never want your AI to touch.

How it works

From "HubSpot" to a working connector URL

Designed for operators, not developers. You never read API docs, manage tokens, or touch a line of code.

  1. 01

    Name it

    A 30-second eligibility check confirms your AI client accepts a custom connector URL, then you pick the software. This page pre-fills that step.

  2. 02

    Describe what you need

    Plain language, not configuration. What should the assistant be able to look up, and what should it be able to change?

  3. 03

    Review your Connector Blueprint

    The exact Read and Write tool list, before you pay anything. Every write ships on in confirm mode and asks before it runs, every tool is individually toggled, and anything destructive carries a distinct warning.

  4. 04

    Deploy and paste the URL

    You get a hosted connector URL plus paste-in instructions matched to your AI client, and a live test panel that confirms the connection.

Identity and team

HubSpot supports Team mode

HubSpot supports per-user credentials, so each team member connects as themselves: upstream audit trails stay truthful, each member's reach is capped by their own HubSpot permissions, and per-member URLs are individually revocable.

Team mode available
OAuth 2.0 sign-in

You sign in to HubSpot and approve access. The connector requests the scopes its tool surface needs at connect time; every write still asks first, you can turn tools off at any time, and no password is ever shared.

The safety story

Write access to HubSpot your IT team will approve

Write tools work from the first minute, previewed through a human confirmation before anything lands, and logged with who, what, and when.

Confirm mode

Enabled writes run through Multi Round-Trip Requests: the tool pauses, shows a human-readable preview of the exact change, and only proceeds with approval. Nothing reaches HubSpot on the model's intent alone.

Guardrails

Any tool can be turned off. Field-level constraints restrict what can be touched, per-tool rate limits are enforced at the gateway edge, and destructive operations ship in dry-run, demonstrating what they would do until you graduate them.

Activity log

Every tool call is logged: who, what, when, result. Write actions and confirmations are highlighted, redaction controls decide how much argument data is stored, and the log is append-only, with updates and deletes refused by the database.

FAQ

Connecting HubSpot: the specifics

Can my AI assistant write to HubSpot?

Yes, with guardrails. Write tools work out of the box in confirm mode: every write asks first, pausing on a preview of the exact change before anything reaches HubSpot. Destructive operations ship in dry-run and never execute until you graduate them, and you can turn off any tool you never want touched.

Is it safe to connect HubSpot to an AI assistant?

Safety is the architecture, not a setting. Every write asks first: it pauses on a human confirmation with the exact change previewed before it reaches HubSpot. Destructive operations demonstrate in dry-run and never execute until you graduate them, any tool can be turned off, and every call lands in an activity log with redaction controls.

If my team uses a HubSpot connector, whose name is on the actions?

The right one. In Team mode each member connects with their own HubSpot identity, so upstream audit trails show the real person, and each member's effective access is the intersection of the connector's guardrails and their own HubSpot permissions. Per-member URLs are individually revocable.

Which AI clients work with a HubSpot connector?

Any client that accepts a remote MCP connector URL: Claude (Free, Pro, Max, Team, and Enterprise), ChatGPT on paid plans with developer mode enabled, Cursor, and other MCP-compatible clients. Team and Enterprise workspaces may need an admin to allow custom connectors first.

How long until a HubSpot connector is live?

Minutes. The verified HubSpot mapping already exists and is maintained by megamcp, so intake ends with a working connector URL.

Anything specific to the HubSpot API worth knowing?

Yes. From our index notes on HubSpot: REST API with granular OAuth scopes; rate limits and some endpoints vary by subscription tier.
