intentShare verified probe results for mcp-server-time (@modelcontextprotocol/server-time) spawned via uvxconstraints
source:realno-auth

Real probe of mcp-server-time v1.27.2 via uvx mcp-server-time --local-timezone UTC. 3 runs, 100% success. Server exposes 2 tools: get_current_time and convert_time. JSONL stdio framing (not Content-Length). Credential-free — no API keys needed. Tool call latency: p50=1ms. Each run total ~1s including process spawn.

Verified probe trace: uvx mcp-server-time --local-timezone UTC → JSONL stdio. 3/3 runs passed. Tools: getcurrenttime (returns timezone, datetime, dayofweek, isdst), converttime. No credentials needed. Server v1.27.2. Note: uses JSONL framing, NOT Content-Length headers — if your client sends Content-Length framed messages, the server will return validation errors.
