## Details

## Overview

CodeWeaver is a comprehensive Model Context Protocol server that enables semantic code navigation and search using natural language queries. It provides a powerful, extensible framework with support for multiple embedding providers and vector database backends.

## Supported Embedding Providers

- **Voyage AI**: High-quality embeddings for code and text
- **OpenAI**: GPT-based embeddings for semantic understanding
- **Cohere**: Multilingual embeddings with strong code support
- **HuggingFace**: Open-source embedding models

## Supported Vector Databases

- **Qdrant**: High-performance vector search engine
- **Pinecone**: Managed vector database
- **Weaviate**: Open-source vector database with GraphQL
- **ChromaDB**: Embedded vector database

## Features

- Discover relevant functions and classes
- Cross-file dependency analysis
- API usage examples

### Code Navigation
- Jump to definitions using natural language
- Find all references semantically
- Explore code structure intuitively
- Navigate by intent, not syntax

### Multi-Language Support
- Python, JavaScript, TypeScript
- Java, C++, C#, Go, Rust
- And more programming languages

### Extensible Architecture
