Project Gumball
15 serversUnverified
A directory of the Gumball tools, a live view of who is calling them, and a single MCP server that exposes every tool in the portfolio — so an agent installs once and gets all of them rather than hunting down one server per capability.
Project Gumball (gumballtools.com) publishes 15 MCP servers on the Official MCP Registry, all run remotely. That ranks it #54 of 16,990 companies by servers shipped, with its latest release on Sep 6, 2026.
