Methodology
How we test
Every comparison uses the same setup. Run them yourself.
Same tool
Hello world — identical input, identical output. No advantage from tool complexity.
HTTP transport
JSON-RPC 2.0 over HTTP POST. The protocol MCP clients use in production.
Docker isolated
Each server in its own container. Pinned versions. No host interference.
5 min sustained
Not a burst test. 300 seconds of continuous load. Snapshots every 10 seconds.
