Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

  }
}

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 [email protected]."

Claude will:

  1. Search for the contact by email using hubspot_crm_search
  2. Create the deal with hubspot_crm_create (objectType: deals)
  3. Create the line item with hubspot_crm_create (objectType: lineItems)
  4. Link them with hubspot_associations_create
  5. 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:

  1. Use hubspot_crm_search with filterGroups combining closedate BETWEEN and amount GT operators
  2. Set sorts to [{ propertyName: "amount", direction: "DESCENDING" }]
  3. 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:

  1. Use hubspot_workflows_list to find the onboarding workflow (filtering by objectTypeId for contacts)
  2. Verify the contact exists with hubspot_crm_get
  3. Enroll with hubspot_enrollment_enroll
  4. 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 |
