Codehelper

Local-first repo intelligence for AI coding assistants.

Codehelper indexes git repositories on your machine, builds a symbol and call graph, and exposes 60+ MCP tools so Cursor, Claude Code, Codex, and other MCP clients can search, understand, and safely change your code — without uploading the whole repo to a cloud model.

---

Three reasons to use Codehelper

1. Project-aware agents — Search symbols, callers, and blast radius locally instead of grepping whole files.
2. Works offline — No API keys; your code stays on your machine.
3. Fits your editor — MCP for Cursor, Claude Code, Codex; one codehelper init per repo.

Installation

Linux / macOS (recommended):

curl -fsSL https://raw.githubusercontent.com/VeyrForge/codehelper/main/scripts/install.sh | sh

Windows (PowerShell):

powershell -ExecutionPolicy Bypass -File .\scripts\install.ps1

From source (requires Go 1.25+, CGO, and a C compiler):

git clone https://github.com/VeyrForge/codehelper.git && cd codehelper
npm run build

Prebuilt 3.0.0 bundles (Linux, macOS, Windows) include codehelper, MCP server, ge 1.0.0, and greencompress 1.0.0 on GitHub Releases.

Updates: codehelper upgrade downloads the latest release from VeyrForge/codehelper. codehelper update rebuilds from a local git checkout.

---

30-second example

cd your-git-repo
codehelper init
codehelper help tools --main

Reload Cursor or Claude Code after the first init, then call project_context once per session so the agent knows which tools exist and how fresh the index is.

See it work

No bundled demo video yet — here is a typical first session:

$ codehelper init
init: ready — index + watch daemon active

$ codehelper status
symbols: 1247  edges: 3891  freshness: current

$ codehelper help tools --main
  project_context  bootstrap tool catalog + index stats
  query            search the symbol graph
  context          source + callers + callees
  impact           blast radius before you edit

Supported platforms

Platform	Install	Notes
Linux	scripts/install.sh	Full support; primary CI target
macOS	scripts/install.sh	Universal + per-arch release binaries
Windows	scripts/install.ps1	x64 supported

Client	Setup
Cursor	Per-project .mcp.json via codehelper init
Claude Code	Managed block in ~/.claude.json
Codex	Reads generated AGENTS.md

---

How it works

Layer	Technology
Indexing	tree-sitter parsers + SQLite symbol/call graph
Search	BM25 + trigrams + call-graph ranking (optional semantic rerank via local embed server)
MCP transport	stdio (default) or HTTP (codehelper mcp --http :8765)
Optional LLM	Green Engine embed/chat + Green Compress weights

init indexes the repo, starts the watch daemon, wires MCP for your editor, and writes agent rules. Optional local dashboard: ge ui serve → http://127.0.0.1:8780

Documentation

• docs/MCP_TOOLS.md — MCP tool reference
• docs/BENCHMARK.md — benchmark results
• CHANGELOG.md — version history
• third_party/README.md — bundled Green stack binaries

---

Limitations

• Requires a git repository for indexing.
• CGO and a C compiler are required to build from source (tree-sitter).
• Semantic rerank and some enrichment features need optional local LLM services (Green Engine).
• Windows arm64 prebuilt CI is temporarily disabled; x64 is fully supported.
