Plugins

Connect DeepSeek Harness Web to MySQL, MariaDB, PostgreSQL, SQL Server, Oracle and MongoDB for schema discovery and read-only queries through session-authorized MCP tools.

Six RF calculators as agent tools: level conversion, link budget and maximum range, cascade noise figure, Shannon capacity, and impedance match.

Pre-launch and runtime HTTP proxy control: writes the proxy into DSH's user-level .env so the launcher and the requests before any plugin loads use it, then keeps that file in sync from a switch in the Plugins page.

One switch that takes an MCP server's tool schemas and its instructions block out of the model context for every agent, live and without a restart, built for the 207 tool schemas REA registers whether or not a task is reverse engineering. A pill in the composer dock, /rea on|off|status|toggle, and GET/POST /rea-toggle/state; the position is remembered across restarts and subagents are covered before their first step.

Trip planning workspace for DeepSeek Harness: a map page with day-by-day stops, roam_* tools that draft, review and adopt an itinerary, and optional MCP sidecars for rail tickets and Xiaohongshu notes.

Read-only inventory of every agent preset for the Web GUI, with a matrix of which preset holds which tools, MCP servers and skills, plus CLIs that move a plugin between presets.

Reads the installed plugins, MCP servers and skills, groups them by capability, and reports which preset each belongs in; can register one preset per category on request.

Turn English audiobooks (MP3) and documents into listening lessons: transcribe every sentence locally with the speech model DSH voice input already downloaded (about 241 MB, fetched on first use if missing; ffmpeg required), proofread and explain each sentence with your DSH model, then drill with blind listening, intensive listening and spaced repetition, with Chinese-dubbing export and offline Kokoro voices; ships a sidebar panel and four AI tools.

Ship a local DSH plugin project to GitHub and the plugin market in one call: preflight, per-file upload with byte verification, the market registry PR, then pull every published file back and compare bytes.

Let the agent restart its own DSH host: schedule a self-restart, finish the turn first, then a detached helper stops and relaunches the app and reports what happened. Dry-run, a status check, and an optional "when can I blink" confirmation are built in.

One screen for every work you have shipped: local project facts, GitHub stars and last push, whether the plugin market has picked it up and how many downloads it has, plus pending pull-request wait times against the upstream median.

Windows GUI automation reliability layer: probes whether a window is minimized, foreground or DPI-scaled, then clicks and types with the coordinate space and activation order handled for you. Zero dependencies, local only.

Hand a local file to any program's file picker: wait for the native Open dialog, paste the path through the clipboard, read it back to verify character by character, then confirm. The target is always explicit and every step leaves evidence. Windows only (EnumWindows / UI Automation).

Take a local video all the way to a Douyin creator post: open the upload page, trigger the picker, hand the file over with verification, fill the title, set visibility - then stop before publishing unless explicitly told to publish.

Web search, page fetch and one-call research through DeepSeek's official Search and Fetch API; needs a DeepSeek API key.

Creates and edits Feishu and Lark cloud content through ten tools - Bitable databases and their records, documents with Markdown converted to native blocks, spreadsheets, wikis, drive files and messages - plus Base V3 dashboard charts and server-side aggregate queries.

Local BM25 auto-recall, a fail-closed write guard, a static doctor and a memory panel for an Engramory markdown store. No network, no daemon and no model calls unless you opt in; recall quality is measured by a reproducible benchmark in the repository.

Hides other memory plugins' context sections and tools inside a chosen DSH preset, so that session gets a clean context. Off by default; ships a read-only diagnostic tool.

Local long-term memory for DSH: browse, search (BM25 + synonyms) and edit entries in a panel; folders, archive and a recycle bin; choose per session what to inject; model-written memories need your approval; import/export backups; optionally sync across devices via your own Git or WebDAV.

Local code memory with automatic source context, symbol lookup, vector search, and dependency graphs for JavaScript and TypeScript projects.

Runs the upstream Headroom compression toolkit (headroom-ai, Apache-2.0) inside DeepSeek Harness over MCP: headroom_compress, headroom_retrieve and headroom_stats are exposed as mcp__headroom__* tools backed by the upstream server, installed on demand by uvx. Compression is lossy but reversible — originals are fetched back by hash from a local CCR store. Also ships a registrar that adds DeepSeek Harness to Headroom's own MCP registry, and a model-header sanitizer for the upstream proxy.

Turns guard denials, gate failures and human thumb-downs into project lessons, and injects only the rules a human has armed into each new session of that project; it registers no model tools and is reviewed through its settings card.

Persistent SQLite session state, story memory and recall, repositories, and model-facing record tools for DSH roleplay plugins.

Registers the Akasha Book memory server over stdio and exposes its 22 akasha_* tools to DeepSeek Harness, covering lookup, briefs, revision chains, audits and session recall. Companions: Hindsight (repo memory), OpenViking (user memory), and the built-in session search (see repo README). Setup: clone the repo, copy core/ aside, then replace <AKASHA_DIR> in cordis.patch.yml with its absolute path (or set the AKASHA_DIR env var); plugins fail loudly while the placeholder remains.
