How to Connect HubSpot to Gemini via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → HubSpot, paste your credentials, mint an MCP API key and you're done. No Docker, no git clone, no local server.

HubSpot + Gemini

Let your AI work in HubSpot CRM: search and update contacts, companies, deals and tickets, see who is linked to what, check pipelines and owners, and log notes and tasks. One account, through a service key you create yourself.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

HUBSPOT_ACCESS_TOKEN

Step 1 — Get credentials

1. In HubSpot, open Development in the left sidebar, then Keys → Service keys, and click Create service key. You need to be a super admin or a user with Developer tools access.
2. Name the key (for example "AnythingMCP"), click Add new scope, tick the scopes listed below, then click Update and Create.
3. Open the key, click Show, then Copy. Service keys start with pat- (for example pat-eu1-...).
4. Paste the key into HUBSPOT_ACCESS_TOKEN, without the word Bearer, then install the connector.
5. Start with hubspot_get_account: it shows which HubSpot account (Hub ID) the key belongs to, its time zone and its currency.

Legacy private apps: older accounts may still have a private app (Development → Legacy apps, previously Settings → Integrations → Private Apps). Its access token works the same way: paste it into HUBSPOT_ACCESS_TOKEN.

Scopes:

• Read: crm.objects.contacts.read (also covers notes and tasks), crm.objects.companies.read, crm.objects.deals.read, crm.objects.tickets.read, crm.objects.owners.read.
• Write: crm.objects.contacts.write (also needed for notes and tasks), crm.objects.companies.write, crm.objects.deals.write, crm.objects.tickets.write.

Read-only setup: give the key only the read scopes and disable hubspot_create_object, hubspot_update_object, hubspot_associate_records, hubspot_create_note and hubspot_create_task.

Switched off at install: hubspot_archive_object. Turn it on only if the AI should delete records. Archived records go to HubSpot's recycling bin and can be restored there for 90 days.

Data privacy settings: if data privacy (GDPR) is turned on in your HubSpot account, HubSpot requires a legal basis for processing, the property hs_legal_basis, on every new contact. Tell the AI which legal basis to use when it creates contacts; without it HubSpot answers "The following required properties were missing".

Limits: HubSpot allows 100 requests per 10 seconds per key on Free and Starter (more on Professional and Enterprise), 250,000 requests a day per account and 5 searches per second. Over a limit HubSpot answers 429: wait a few seconds and try again.

Common errors: 401 means the key is wrong, expired or was rotated: copy it again. 403 names the missing scope: add it to the key under Edit. 404 means a wrong id or object type. 400 VALIDATION_ERROR names the property or filter that is wrong, for example an unknown property name or a dropdown value that is not one of its options.

The connector does not handle marketing emails, forms, lists, workflows, files, quotes and line item pricing, merges or batch writes.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (on Windows %USERPROFILE%\.gemini\settings.json). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}

1. Create an MCP API key in AnythingMCP under MCP Servers → your server → API keys, and paste it in place of YOUR_MCP_API_KEY.
2. Save the file and restart gemini.
3. Run /mcp inside Gemini CLI (or gemini mcp list in your shell): anythingmcp should show as connected.
4. Start prompting: Gemini CLI can now call the HubSpot tools.

FAQ

Where does Gemini CLI look for MCP servers? In ~/.gemini/settings.json for your user, or in .gemini/settings.json inside a project. gemini mcp list shows each server and whether it connects.
