note: Panel Queue was accepted for routing review, but implementation is held because `00001KVHKWNQS` is currently inprogress with active Coder work. Leave this MCP foundation Ticket queued; reroute when current implementation capacity is free.

author: yoi-orchestrator


summary: Named local stdio MCP server configuration and trust policy metadataを追加する。This Ticket only parses/validates config and diagnostics; it must not spawn subprocesses or implement JSON-RPC lifecycle. Command/env/secret fields must fail closed, redact sensitive values, and document that local MCP executables run with user OS permissions outside Yoi feature sandbox authority.

role_plan: Orchestrator は acceptance records を commit 後、専用 implementation worktree `.worktree/00001KVHR3WRF-mcp-stdio-config-trust` を作成し、Coder をその child worktree への narrow write scope で起動する。Coder 実装後、Reviewer が config schema、trust boundary docs、secret redaction、fail-closed validation、no auto-start/no process execution、Profile/config layering separation を確認する。
