HubSpot MCP Server (Official)
hubspot-mcp
HubSpot's official MCP server (npx @hubspot/mcp-server): 21 CRM tools — list/search/read objects (contacts, companies, deals), properties, associations, engagements and workflows, plus batch create/update. Auth via a private-app token or service key.
When to use
Agents reading or updating HubSpot CRM data — contacts, companies, deals, properties, associations and engagements — with explicit tools and batch operations.
When not to use
Tight context budgets (21 tool defs ~9.3k tokens), or write flows whose scopes you have not granted the token — writes 403 without them.

Evaluation
Not conclusively measured — verified with a read-scoped token, so batch create/update were not exercised as idempotent.
