Model Context Protocol (MCP) allows you to integrate Claude Context with your favorite AI coding assistants, e.g. Claude Code.


## Quick Start

### Prerequisites

Before using the MCP server, make sure you have:
- API key for your chosen embedding provider (OpenAI, VoyageAI, Gemini, or Ollama setup)
- Milvus vector database (local or cloud)

> 💡 **Setup Help:** See the [main project setup guide](../../README.md#-quick-start) for detailed installation instructions.

### Prepare Environment Variables

#### Embedding Provider Configuration

Claude Context MCP supports multiple embedding providers. Choose the one that best fits your needs:

> 📋 **Quick Reference**: For a complete list of environment variables and their descriptions, see the [Environment Variables Guide](../../docs/getting-started/environment-variables.md).

#### Get a free vector database on Zilliz Cloud

Claude Context needs a vector database. You can [sign up](https://cloud.zilliz.com/signup?utm_source=github&utm_medium=referral&utm_campaign=2507-codecontext-readme) on Zilliz Cloud to get an API key.

![](../../assets/signup_and_get_apikey.png)

Copy your Personal Key to replace `your-zilliz-cloud-api-key` in the configuration examples.

```bash
MILVUS_TOKEN=your-zilliz-cloud-api-key
``` 


#### Embedding Batch Size
You can set the embedding batch size to optimize the performance of the MCP server, depending on your embedding model throughput. The default value is 100.
```bash
EMBEDDING_BATCH_SIZE=512
```

#### Custom File Processing (Optional)
You can configure custom file extensions and ignore patterns globally via environment variables:

```bash
# Additional file extensions to include beyond defaults
CUSTOM_EXTENSIONS=.vue,.svelte,.astro,.twig

# Additional ignore patterns to exclude files/directories
CUSTOM_IGNORE_PATTERNS=temp/**,*.backup,private/**,uploads/**
```

These settings work in combination with tool parameters - patterns from both sources will be merged together.
