+### Changed
+- **`8sync ccc kit` tắt MCP chrome-devtools của ECC trên mọi máy, giữ skill/agent/command `ecc:*`.** Owner (2026-10-27): "Tắt MCP chrome-devtools của ECC trên mọi máy", "spam terminal ram, cpu lag". `.mcp.json` gốc của ECC chạy `npx -y chrome-devtools-mcp@1.10.1` ở mỗi phiên (4 tiến trình node/cmd mỗi phiên; máy owner có 14 phiên = 56 tiến trình) dù `plugin.json` ghi không có MCP; duyệt web đã có ego-browser.
+  - Kit thêm `{ "serverName": "plugin:ecc:chrome-devtools" }` vào `deniedMcpServers` trong `~/.claude/settings.json` (Claude Code nhận denylist ở settings người dùng, code.claude.com/docs/en/managed-mcp). Entry deny khác của người dùng được giữ; không thêm trùng.
+  - Kiểm trên Windows: trước khi deny `claude mcp list` hiện `plugin:ecc:chrome-devtools … Connected`, sau khi deny server biến mất. Phiên đang mở vẫn giữ tiến trình cũ tới khi đóng phiên.

 ## Current
+v0.110.87: kit tắt MCP chrome-devtools của ECC (`deniedMcpServers` serverName `plugin:ecc:chrome-devtools`), giữ skill/agent `ecc:*`.
 v0.110.86: `8sync ccc kit` bật plugin ECC (affaan-m/ECC, MIT) trên mọi máy: 71 agent, 311 skill, 97 command `ecc:*`, marketplace `autoUpdate`, hook ECC tắt (`ECC_HOOKS_ENABLED=false`), giữ giá trị owner; policy org cho phép `affaan-m/ECC`.
 v0.110.85: R&D từ Feynman v0.5.58 (MIT): `deep-research` v3 (plan 6 mục, scale 0–6 researcher, claim `(D)` cần 2 nguồn, verifier trước `research-reviewer`, provenance PASS/BLOCKED), `/autoresearch` chỉ owner khởi động (Start card, worktree, keep rule theo nhiễu, held-out), test frontmatter YAML chặt; `8sync harness browser ego install|status` cài ego lite chính thức (Windows: chữ ký CITRO LABS).
 v0.110.84: hq-ui `pnpm dev`/`pnpm start` work on Windows (`scripts/next.mjs`, no POSIX `${PORT:-…}`); HQ on Next 16.4.1 (GHSA-2464-fhr4-w9xw, GHSA-673q-mjm6-r5xr, GHSA-p3m5-59mp-jv5r).
