dsh-gitnexus-plugin

DeepSeek Harness (DSH) profile bundle: GitNexus MCP integration — indexes codebases into knowledge graphs and exposes mcp__gitnexus__* tools so agents can analyze dependencies, call chains, and execution flows with architectural clarity.

Built on GitNexus.

Install via repo URL

From the DSH plugin hub / profile bundles UI, install with the repo URL:

https://github.com/akash-digitavision/dsh-gitnexus-plugin

Or via the official DSH CLI (forwards pnpm inside the web profile directory; DSH auto-loads and registers the plugin on startup):

dsh plugin --profile web add github:akash-digitavision/dsh-gitnexus-plugin

Then restart DeepSeek Harness — every agent and preset on the profile sees the mcp__gitnexus__* tools.

Prerequisites

Requirement	Install	Notes
Node.js ≥ 20	https://nodejs.org/	Required by GitNexus
GitNexus CLI (recommended)	npm i -g gitnexus	Fastest MCP startup — no npx cold-cache delay

The bundle spawns the GitNexus stdio MCP server (gitnexus mcp), which serves all indexed repos. Index any repo you want queryable:

cd your-repo
gitnexus analyze        # or: npx gitnexus@latest analyze

Configuration

Command resolution for the MCP row:

1. GITNEXUS_COMMAND env var (absolute path to the gitnexus launcher) — takes precedence;
2. otherwise gitnexus from PATH.

Windows note: npm's global gitnexus is a .cmd shim. If the MCP client cannot spawn it, pin it explicitly and restart DSH:

setx GITNEXUS_COMMAND "%APPDATA%\npm\gitnexus.cmd"

Tools exposed

Tool	Use for
query	Concept / execution-flow search across the graph
context	Full context for a named symbol
impact	Blast radius before editing a symbol (callers, processes, risk)
explain	Taint findings & structural explanation of a file/symbol
detect_changes	Graph change analysis before committing
rename	Call-graph-aware symbol rename

Exact surface depends on your GitNexus version (gitnexus --version). Resources such as gitnexus://repo/<name>/context, /clusters, /processes are also served per indexed repo.

What this bundle does

cordis.patch.yml inserts one HOST-plane row:

• mcp-gitnexus → @deepseek-ai/dsh-mcp-client, transport: stdio, command: gitnexus, args: ['mcp'], 120 s tool timeout, non-fatal on startup error (the server simply stays absent if GitNexus is not installed).

index.js is a behaviour-free resolvable entry shim satisfying the DSH plugin-spec check — configuration is supplied entirely by the patch file.
