Open-source HubSpot MCP alternatives
HubSpot's MCP server is closed and run by HubSpot. If you would rather use a server whose source you can read, audit, and fork, every option below publishes its code. That matters in a CRM, where the agent can read and write customer records and you want to know exactly which calls it can make.
These are the open-source servers people line up against HubSpot. Some are full CRMs, others reframe the customer record as support or conversation, and all of them let you pin the version you trust.

How to choose
Among the open-source options, Salesforce is the deepest CRM and Pipedrive the leaner sales-focused one, both auditable in source. Zendesk and Intercom reframe the record as support and conversation, Telegram and LINE cover messaging, Atlassian and monday.com handle customer work as issues and boards. Read the repo before wiring any of them to live customer data.
FAQ
- Is the HubSpot MCP server open source?
- No. HubSpot runs the server itself and does not publish its source, so you authenticate over OAuth and cannot audit or modify it. Every alternative on this page ships its code publicly.
- Why pick an open-source CRM server over HubSpot's hosted one?
- You can read exactly which CRM calls the agent is able to make, pin or patch the version you run, and keep credentials on infrastructure you control. The trade-off is operating it yourself rather than relying on HubSpot to keep it running.
