MCP tool tour — the BRAF V600E variant-to-trials chain (zh notes)

PASS11sprompt: zhartifact: zh

Prompt (verbatim)

n/a — this scenario is a deterministic stdio JSON-RPC probe, not a prompted agent session.

What happened

The WorkBuddy connector's third zh example (“查找 BRAF V600E 变异的相关药物与临床试验”) executed at the raw MCP layer.
Four keyless calls chain variant -> gene -> drugs -> trials in 11 seconds, token-free.
Same probe mechanics as the EN tour; bilingual notes captured with each response.
