Client compatibility pass
ClaudeCursor inferredVS Code inferredPython SDK
Cursor and VS Code embed the official TypeScript SDK client; their chips are inferred from the TypeScript SDK rows (no GUI automation). Claude Code is verified with a claude mcp list health check — a real handshake over its own transport.
| Client | local macOS |

| TypeScript SDK client (current) v1.30.0 embedded by Cursor, VS Code, Claude Desktop, Windsurf | pass 3 tools via ts-sdk 1.30.0 |

Unauthenticated initialize
HTTP 200: the server accepts requests without a token, so OAuth checks do not apply.

Error ergonomics pass 65/100
10 malformed inputs per tool (missing/mistyped/null/out-of-range/unknown fields …). Each error response is graded on code · cause · fix · retryable; 17 distinct error shapes graded by the judge ($0.0000), cached.
