Required Scopes

Grant only the scopes your use-case needs:

Toolset	Required Scopes

{
  "mcpServers": {
    "hubspot": {
      "command": "npx",
      "args": ["-y", "@nubiia/mcp-hubspot"],
      "env": {
        "HUBSPOT_ACCESS_TOKEN": "pat-na1-...",

Usage Examples

Create a deal and attach products

"Create a deal named 'Acme Corp - Enterprise Plan' closing on March 31st, add a line item for the Enterprise annual plan at $24,000, and associate it with the contact [e-mail]."

Claude will:

• Search for the contact by email using hubspot_crm_search
• Create the deal with hubspot_crm_create (objectType: deals)
• Create the line item with hubspot_crm_create (objectType: lineItems)
• Link them with hubspot_associations_create
• Associate the contact with hubspot_associations_create

Find all deals closing this month above $10k

"Search for all open deals with a close date in the current month and amount greater than $10,000. Sort by amount descending."

Claude will:

• Use hubspot_crm_search with filterGroups combining closedate BETWEEN and amount GT operators
• Set sorts to [{ propertyName: "amount", direction: "DESCENDING" }]
• Paginate through results using the after cursor if there are more than one page

Enroll a contact who just filled a form in the onboarding workflow

"The contact with ID 98765 just submitted the trial sign-up form. Enroll them in the onboarding workflow."

Claude will:

• Use hubspot_workflows_list to find the onboarding workflow (filtering by objectTypeId for contacts)
• Verify the contact exists with hubspot_crm_get
• Enroll with hubspot_enrollment_enroll
• Confirm enrollment with hubspot_enrollment_get_enrollments

Workflows v4 BETA

The workflows toolset uses HubSpot's Workflows v4 API, which is currently in BETA:

• Breaking changes may occur without notice
• Access requires explicit approval from HubSpot — contact HubSpot support if you receive 403 errors
• The following tools are included in the workflows toolset: hubspot_workflows_list, hubspot_workflows_get, hubspot_workflows_create, hubspot_workflows_update, hubspot_workflows_delete, hubspot_workflows_batch_read, hubspot_workflows_email_campaigns, hubspot_workflows_performance, hubspot_workflows_id_mappings

For stable, read-only access to existing workflows, use the legacy v3 tools included in the automation toolset:

• hubspot_workflows_v3_list — list all workflows
• hubspot_workflows_v3_get — get a specific workflow by ID

Actions Toolset (Phase 7)

The actions toolset exposes 16 tools for managing Custom Workflow Action definitions — the reusable action types that developers can publish to the HubSpot Workflows editor.

Required environment variables

Variable	Required	Description
HUBSPOT_DEVELOPER_API_KEY	Yes (for actions)	HubSpot developer API key — obtain from your developer account at developers.hubspot.com
HUBSPOT_APP_ID	Yes (for actions)	The HubSpot App ID that owns the action definitions

Activation

Actions tools are only registered when HUBSPOT_DEVELOPER_API_KEY is present. They do not appear in the tool list when only HUBSPOT_ACCESS_TOKEN is configured. You can also explicitly enable them via HUBSPOT_TOOLSETS=actions (still requires the developer key).

Authentication

All 16 hubspot_actions_* tools authenticate via hapikey (developer API key appended to the query string), not the Private App bearer token used by the other 37 tools.

Tools

Tool	Description
hubspot_actions_list	List all custom action definitions for an app
hubspot_actions_create	Create a new action definition
hubspot_actions_get	Get a single action definition
hubspot_actions_update	Update (PATCH) an action definition
hubspot_actions_delete	Delete an action definition
hubspot_actions_revisions_list	List all revisions for an action
hubspot_actions_revisions_get	Get a specific revision
hubspot_actions_functions_list	List all functions on an action
hubspot_actions_functions_get_by_type	Get a function by type
hubspot_actions_functions_put	Create or replace a function by type
hubspot_actions_functions_delete_by_type	Delete a function by type
hubspot_actions_functions_get_by_id	Get a function by type and ID
hubspot_actions_functions_update_by_id	Replace a function by type and ID
hubspot_actions_functions_delete_by_id	Delete a function by type and ID
hubspot_actions_requires_object_get	Get the requires-object setting for an action
hubspot_actions_requires_object_set	Set the requires-object setting for an action

Claude Desktop configuration example

{
  "mcpServers": {
    "hubspot": {
      "command": "npx",
      "args": ["-y", "@nubiia/mcp-hubspot"],
      "env": {
        "HUBSPOT_ACCESS_TOKEN": "pat-na1-...",
        "HUBSPOT_DEVELOPER_API_KEY": "your-developer-api-key",
        "HUBSPOT_APP_ID": "123456"
      }
    }
  }
}

Known Limitations

• Search latency: Records created or updated via the API may take 1–5 minutes to appear in hubspot_crm_search results due to HubSpot's indexing pipeline
• Batch cap: All hubspot_crm_batch_* tools enforce a hard limit of 100 objects per call; split larger sets across multiple calls
• Workflows v4 API: Subject to breaking changes while in BETA; HubSpot support approval required for access
• Quote assembly: hubspot_quotes_assemble requires the deal to have at least one associated line item; the call will fail otherwise

MCP Resources

Three static reference resources are available to LLM clients:

URI	Name	Description
hubspot://scopes-guide	HubSpot Private App Scopes Guide	Required OAuth scopes per toolset/domain
hubspot://crm-object-types	CRM Object Types Catalog	Supported objectType values and key properties
hubspot://conventions	HubSpot MCP Usage Conventions	Rate limits, batch caps, search latency, pagination

MCP Prompts

Five guided workflow prompts help orchestrate multi-step operations:

Prompt	Description
create-deal-with-line-items	Create a Deal and attach Line Items from HubSpot Products
assemble-quote	Assemble a HubSpot Quote from an existing Deal
log-engagement-and-associate	Log a CRM engagement (call, email, or meeting) and associate it with contacts/deals
enroll-contact-in-workflow	Enroll a contact (or other object) in a HubSpot Workflow
search-crm-records	Search CRM records with filters, sort, and pagination
