Test MCP By CLI

Validate MCP servers with mcp-cli (philschmid/mcp-cli v0.3.0) using release-verified behavior first, then use official repo source only when it matches what the installed binary actually does.

Core rules

• Execute commands directly and sequentially.
• Do not write helper scripts unless explicitly requested.
• Treat server work as incomplete until verification checks pass.
• Prefer single-server commands while debugging.
• After rebuilding a server, always retest with MCP_NO_DAEMON=1.
• Treat mcp-cli --help and real command output as the primary behavioral source for the installed release.
• Remember that call returns the raw MCP JSON envelope on stdout in the installed v0.3.0 binary.
