When the rail runs, every repo lands in one of five bands and every band ships with
the date it was measured: active under 90 days, slowing 90 to 180, quiet 180 to 365, dormant over a
year, and archived. The band is descriptive and never a verdict. A stable server genuinely may not
need commits. But an agent about to write a community MCP wrapper into a workflow deserves to know
the repo has been silent for eight months first, and this directory already has the receipts that
the category churns.
62 of 293 entries already carry a
github.com URL somewhere in their fields, and 47 of those sit in
the mcp_url field. Those repos are free to measure when the rail runs. Nothing below says anything
about whether a repo is healthy.
