Give your AI agents native, governed access to the HubSpot Marketing Hub. 116 purpose-built tools cover campaigns and their budgets, marketing email and its revisions, forms, lists and memberships, marketing events and attendance, workflows and folders — under one policy layer.
No code. One Hub endpoint for every agent.
The DataGrout HubSpot Marketing MCP Server is a native Model Context Protocol server that exposes the Marketing Hub as callable tools for AI agents. Agents can create and clone campaigns with their budgets, spend items and asset associations, build marketing emails with A/B variations, drafts, publications and revision history, create forms and audience lists, register marketing events and attendance, create workflows and folders, and search the contacts and companies those campaigns work from — all through one governed endpoint that enforces side-effect policy and runs Warden preflight on every call.
116 tools across campaigns, email and audience data
Bearer access token, with optional mutual TLS
Read and write allowed, scoped by your policy
The Marketing Hub is where assets, audiences and reporting meet. The groups below follow that shape; the full inventory is in your signed-in workspace.
The container every marketing asset reports into.
Build the send, then keep its history intact.
How contacts arrive, and how they are grouped.
Events, who attended, and what was cancelled.
The logic that moves a contact onward.
Where assets live, and the records they target.
Everything happens in the DataGrout Hub — no code, no per-agent configuration.
In DataGrout, open the Hub Server that will carry your integrations and click Add Integration.
Search for HubSpot Marketing, then select the native MCP Server integration.
Paste the HubSpot access token in Credentials, optionally enable mTLS, then use the Sandbox section to trial calls before they touch live marketing assets.
Expose the campaign, email and list tools the agent needs, then set side-effect and Warden policy.
Access Token (Bearer)
The integration authenticates with a HubSpot access token sent as a Bearer header, entered in the Credentials section of the integration.
Mutual TLS
Enable mTLS in combination with the access token, or on its own when no authentication method is selected, for clients that require certificate-based transport.
Sandbox
A Sandbox section sits beside Credentials. It runs any marketing tool by name with its query variables and custom parameters, and returns a credit-cost estimate instead of executing the call when estimate_only is true — useful before an agent publishes or clones anything.
Marketing Hub responses carry the asset and record IDs an agent needs to chain the next call, plus the fields that describe the object it touched.
The server ships with the same layered policy engine as every DataGrout integration. Security teams set the posture once; every agent inherits it.
Read and write are available. Side effects are governed by your policy, set per integration and inherited from the Hub Server above it.
Policy Controls carry a Warden mode dropdown (Off, Log only, Advisory, Enforce) and a minimum verdict dropdown. The integration also has its own Interaction section, and overriding the parent policy or parent interaction settings is disabled by default.
Campaign and form content is written by the whole marketing team. Warden screens every call in Off, Log only, Advisory or Enforce mode before it executes.
The child can only tighten the parent. Parent permissions stay visible while the override is active, and a child integration never weakens its parent server.
Every execution can return a receipt, a pre-run credit estimate, a Cognitive Trust Certificate and a full execution summary — so an agent's work on your HubSpot Marketing data is always explainable.
Four patterns that show up again and again once a HubSpot Marketing connection is in place.
Create the campaign with its dates, audience and UTM parameters, attach the assets it will use, and record the budget so spend has somewhere to land.
Clone the control email, create an A/B variation, and keep every draft and publication on record so the revision history stays readable.
Register the marketing event, reconcile attendance against the subscriber state that came in, and note the cancellations that need a human.
Search the lists and the contacts inside them, compare that with the campaigns targeting them, and report where the segmentation has drifted.
One Hub endpoint can carry all of them — same policy layer, same observability.
Add the HubSpot Marketing MCP Server to your DataGrout Hub and let agents build campaigns and audiences, with governance on every asset they touch.
