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:
GITNEXUS_COMMAND env var (absolute path to the gitnexus launcher) — takes precedence;- 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.
