v0.1.0 — Initial release

v0.1.0 — Initial release (2026-10-14)

Named database connections for DeepSeek Harness. Configure your MySQL databases in a settings page, then refer to them by name in chat.

✨ Features

• Named connections — say "use 128" (or whatever you named it); the names are contributed to the system prompt, so the model resolves them without host, port, or password ever being restated.
• Settings page — add / edit / delete connections under Settings → Databases, a read-only ↔ read-write dropdown per connection, and a Test button for an on-the-spot connectivity probe. Saving applies immediately, no restart.
• Three tools —
  • db_query: read-only; every statement runs in a server-enforced read-only transaction
  • db_execute: only accepted on connections where you opted in to writes (allowWrite)
  • db_schema: schemas, tables, columns, indexes, and DDL
• Secrets stay local — no password ever reaches the prompt; passwordEnv keeps secrets out of the config file entirely.
• Bilingual UI — the settings page follows the shell's zh/en language setting via locale dictionaries.
• Hot swap — connections changed through the settings page or the API route are addressable immediately, without a restart.

📦 Install

cd <path-to>/dsh-db-connections
npm install

dsh plugin --profile <name> add <path-to>/dsh-db-connections

Requires Node ^22.19.0 || >=24.0.0 and a DeepSeek Harness installation. See README.md for desktop-profile specifics and configuration details（中文说明见 README.zh.md）.

🧪 Quality

10 test suites cover config validation, store round-trip, settings-page rendering, the client bundle, the live loader stack, the write path, and end-to-end integration — including checks that read-only enforcement holds against CTE-led writes and INTO OUTFILE.

中文摘要

为 DeepSeek Harness 提供命名数据库连接：在「设置 → 数据库连接」里配好 MySQL，之后在对话里直接用连接名（例如「用 128 查一下」）。默认只读（服务端强制只读事务），可逐个连接开启读写；密码永不进入提示词，并支持 passwordEnv 从环境变量引用。保存立即生效，无需重启。
