Our reading of OSVcalc, from the data

OSVcalc is a science & research MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was 7 days ago (2026-10-12). For comparison, 73% of science & research servers are active or maintained.

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