Our reading of Clear Line Ops, from the data

Clear Line Ops is a science & research MCP server from mfarrell628, listed in the official MCP Registry.

Its 127 tools add about 26,772 tokens to every model turn, heavier 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 4 days ago (2026-10-14). 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.
