repo-graph — structural codebase map for AI

Zero-config structural codebase map for AI coding assistants.

This extension registers repo-graph as an MCP server in VS Code's agent mode. Install it and your open workspace is mapped automatically — no JSON config, no path to type.

repo-graph gives the AI a graph of your codebase — entities, relationships, and feature flows — so it navigates straight to the files that matter instead of grepping and reading everything first. Works across 20+ languages/frameworks (Go, Rust, TypeScript/React/Angular/Vue, Python, Java, C#, …) with cross-stack linking between frontend calls and backend routes.

Requirements

• uv on your PATH. The extension runs uvx mcp-repo-graph, which fetches the package and its prebuilt Rust engine wheel on first use — no Python or Rust toolchain setup required.

How it works

On activation the extension provisions an MCP stdio server:

uvx mcp-repo-graph --repo <your-workspace-folder>

VS Code's agent then gets repo-graph's 6 tools: orient (repo shape + where the graph is blind), find (a symbol, keyword, stacktrace, failing test, or diff → the ranked nodes that matter), impact (blast radius, dead code flagged ⊘), trace (a feature end-to-end, or the path between two nodes), read (a node's exact source), and refresh (rebuild). The --repo argument follows your active workspace folder automatically.

Usage

1. Install the extension.
2. Open a project folder.
3. In agent mode, repo-graph's tools are available — ask things like "what does this codebase do?" or "trace the checkout flow".
