## 📖 Overview

**Source-MCP** leverages the [Model Context Protocol](https://modelcontextprotocol.io) to provide AI assistants (like Claude, Gemini, and others) with direct access to local files through semantic search.

Instead of manually copy-pasting code or documentation into your prompts, Source-MCP automatically indexes your local repository, generates vector embeddings, and enables the AI to semantically search and retrieve only the most relevant files.

## ✨ Key Features

- **Dual Embedding Support:**
  - **OpenAI:** Uses robust `text-embedding-3-small` (1536 dimensions) for high-quality enterprise embeddings.
  - **FastEmbed (Local):** Uses `sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2` (384 dims). Runs entirely locally, no API keys required, and supports multilingual inquiries.
- **Smart Incremental Indexing:** Uses file fingerprints (modified time + size) to only index new or modified files, ensuring lightning-fast startup times.
- **Auto-Migration:** Automatically detects embedding dimension changes (e.g., switching from OpenAI to FastEmbed) and safely recreates the vector index.
- **Web Dashboard (Port 8000):**
  - **Live Logs:** View real-time indexing and search activity with auto-scroll.
  - **Reindex Base:** Force-wipe the vector DB and manifest for a completely fresh full scan.
  - **Reindex Base:** Force-wipe the vector DB and manifest for a completely fresh full scan.
  - **Search Debugging:** Special endpoint (`/api/search/debug?q=...`) to test raw semantic search scores.

## 🤔 Why local embeddings and `zvec`?

We use [**zvec**](https://github.com/alibaba/zvec), a lightweight, high-performance vector database maintained by Alibaba. `zvec` is embedded directly into the Python process, eliminating the need to set …
