### Description (declared)

# Code GraphRAG MCP Server

A Model Context Protocol server for source-code introspection. It keeps a local-first knowledge graph for your repositories: Tree-sitter derived symbols and relations, AST-aligned chunks, EmbeddingGemma vectors stored in sqlite-vec, and graph traversal through bfsvtab. Wheels ship the native extensions, so the server starts instantly with `uvx`.

## Features

- Hybrid retrieval combining vector search and breadth-first graph expansion over code relations
- Live repository sync via filesystem watcher and job queue
- Deterministic provenance for every symbol, relation, and chunk
- Bundled sqlite-vec and bfsvtab binaries—no manual compilation required

## Installation

```bash
uvx code-graph-rag-mcp serve --config /workspace/config.yaml
```

### MCP manifest example

```json
{
  "mcpServers": {
    "code-graph": {
      "command": "uvx",
      "args": ["code-graph-rag-mcp", "serve", "--config", "/workspace/config.yaml"],
      "env": {
        "CODE_GRAPH_RAG_WATCH_DIR": "/workspace/repo",
        "CODE_GRAPH_RAG_DB_PATH": "/workspace/data/code.sqlite"
      }
    }
  }
}
```

This manifest block works for Claude Desktop (`claude_desktop_config.json`), Cursor (`~/.cursor/mcp.json`), or any other MCP host.

## Configuration

### Minimal `config.yaml`

```yaml
watch:
  dir: "/workspace/repo"
database:
  sqlite_path: "/workspace/data/code.sqlite"
```
