MCP, MCP server
io.github.2s-io/mcp
MCP server for 2s.io — gives any MCP-aware agent 575+ pay-per-call tools: more ground-truth data than any other x402 API, a full AI gateway (chat, image, multi-model consensus), and agent infrastructure (storage, locks, queues, schedules, watchers).
Compatibility: Not stated.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
