Prove the full MCP protocol flow works end-to-end against real servers:
- Self-written fixture server: tool discovery, execution, error handling,
image placeholder, toolPrefix, and clean disposal
- @modelcontextprotocol/server-everything: echo, get-sum, get-tiny-image
- @modelcontextprotocol/server-filesystem: write_file + read_file round-trip,
list_directory with world-verification
All 15 tests keyless and deterministic (no API key needed).
