Our reading of Cerebrum, from the data

Cerebrum is a science & research MCP server from vaticay, listed in the official MCP Registry.

Its 2 tools add about 133 tokens to every model turn, lighter than the science & research median of 2,616 tokens across 126 measured servers (measured 2026-10-19).

Maintenance is active: the last public signal was in the last day (2026-10-19). For comparison, 73% of science & research servers are active or maintained.

With 0 GitHub stars it ranks #442 of 1,435 science & research servers we index.

It runs as a hosted endpoint, so there is nothing to install.

Install Cerebrum MCP server

claude mcp add --transport http cerebrum https://askcerebrum.org/mcp
