Does Follow Up Boss Have an MCP Server? What Exists Today

• The API. Follow Up Boss publishes a REST API at api.followupboss.com/v1 with endpoints for people, events, notes, deals and tasks, among others. Its documentation index lists API references, OAuth guides and inbox-app guides, and no MCP server.
• A listed third-party server. The Follow Up Boss integrations directory lists Ace AI, which advertises “exclusive MCP to access your data in Claude & ChatGPT.” Ace AI’s terms identify it as a product of Moon Sherpa Labs, and MCP access is part of its paid tier.
• Unofficial open-source servers. On GitHub, mindwear-capitian/followupboss-mcp-server describes itself as a 160-tool, self-hosted server under the Elastic License 2.0, and benlaube/fub-mcp is a smaller project with no license declared on GitHub. Neither is built or supported by Follow Up Boss.

1. Use a third-party MCP service that connects to your Follow Up Boss account, after reviewing who operates it and what it can write.
2. Self-host a community server and give it a Follow Up Boss API key. Keys are per user, found under Admin, then API, and sent with HTTP Basic authentication.
3. Build your own agent layer on the API, which supports both API-key and OAuth authentication.

Whichever route you take, the key or token decides the reach. Follow Up Boss states that an API key “provides the same privileges as the user’s login credentials”: an agent’s key sees only that agent’s assigned contacts, while a broker’s key sees everyone in the account.

• No vendor support. Problems with a third-party or community server are not Follow Up Boss’s to fix, and a change to the API can break a server its maintainer has not updated.
• Credential exposure. Self-hosting means storing an API key that carries the user’s full privileges. Use the narrowest user role that does the job.
• Licensing. Read the license before deploying a community server inside a brokerage; the two projects above differ, and one declares none.
• Write actions. Both community projects above document create, update and delete operations, and the larger one warns in its own README that it has full read and write access. Test on a non-production account first.
