"Rust (stable)" understates the floor. rmcp, darling and time declare
rust-version 1.88, and cargo metadata resolves both crates to 1.88.
The Ruby aside said 3.3 also satisfies the gems. anthropic requires
>= 3.2.0 and mcp >= 2.7.0, so the gem floor was 3.2, and 3.2 reached EOL
on 2026-03-31. CI runs 3.4, which is what the READMEs now state.
The Go and Rust clients take a command plus arguments, not a path to a
server script.
Removed the commit-message convention, which is attributed to the MCP
contributing guidelines but does not appear in them. Added the
AI_POLICY.md link that CONTRIBUTING.md points to.
