The MCP registry's growth has been steady for weeks — a dozen new servers here, twenty there. Yesterday it wasn't steady. 123 new servers appeared in a single 24-hour scan, pushing the total from 2,317 to 2,440. Zero removed. A 5.3% jump, almost entirely driven by two publishers.
Two Publishers, 89 Servers
Ansvar (eu.ansvar) exploded from 6 servers to 76 overnight — one person, one template, 70 country-specific law servers. They're now the second-largest publisher in the entire registry. Their pitch: "you shouldn't need a law degree and 47 browser tabs. Ask Claude. Get the exact article. With context."
IOWarp (io.github.iowarp) brought 16 HPC-focused servers from a $5M NSF-funded research lab. Wrappers for HDF5, ADIOS, Slurm, Darshan, ParaView. They describe it as "one unified interface. 16 MCP servers. 150+ specialized tools. Built for research."

Most new entries land in Low Trust. Normal for fresh registrations — trust is earned over time through commits, releases, and community adoption.
Notable New Entries
- Exploit Intel — anonymous operators, no source code, wants your credentials. Score: 29.
- Charlotte — headless browser MCP returning 336 characters where Playwright returns 61,230. Score: 61.
- Two proxy servers — a commercial marketplace vs. an open-source context optimizer. The middleware layer is forming.
- Hebcal — Jewish calendar data via MCP. Five contributors, repo age >90 days. Score: 63.
- SBOM-MCP — Software Bill of Materials for supply chain security. Score: 41.
What to Watch
- Mass-parameterized publishing is here. The registry has no concept of grouping templated clones from a single publisher.
- The publisher landscape is long-tail. 1,516 publishers have exactly one server. Only 32 have five or more.
- Scientific computing found MCP. IOWarp is the first serious academic play.
