**Claude Context** is an MCP plugin that adds semantic code search to Claude Code and other AI coding agents, giving them deep context from your entire codebase.

🧠 **Your Entire Codebase as Context**: Claude Context uses semantic search to find all relevant code from millions of lines. No multi-round discovery needed. It brings results straight into the Claude's context.

💰 **Cost-Effective for Large Codebases**: Instead of loading entire directories into Claude for every request, which can be very expensive, Claude Context efficiently stores your codebase in a vector database and only uses related code in context to keep your costs manageable.

Model Context Protocol (MCP) allows you to integrate Claude Context with your favorite AI coding assistants, e.g. Claude Code.

## Quick Start

### Prerequisites

<details>
<summary>Get a free vector database on Zilliz Cloud 👈</summary>

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.
</details>

<details>
<summary>Get OpenAI API Key for embedding model</summary>

You need an OpenAI API key for the embedding model. You can get one by signing up at [OpenAI](https://platform.openai.com/api-keys).  

Your API key will look like this: it always starts with `sk-`.  
Copy your key and use it in the configuration examples below as `your-openai-api-key`.

</details>

### Configure MCP for Claude Code

**System Requirements:**

- Node.js >= 20.0.0 and < 24.0.0

> Claude Context is not compatible with Node.js 24.0.0, you need downgrade it first if your node version is greater or equal to 24.

#### Configuration

Use the command line interface to add the Claude Context MCP server:

```bash
claude mcp add claude-context \
  -e OPENAI_API_KEY=sk-your-openai-api-key \
  -e MILVUS_TOKEN=your-zilliz-cloud-api-key \
  -- npx @zilliz/claude-context-mcp@latest
```

See the [Claude Code MCP documentation](https://docs.anthropic.com/en/docs/claude-code/mcp) for more details about MCP server management.

### Other MCP Client Configurations

<details>
<summary><strong>OpenAI Codex CLI</strong></summary>

Codex CLI uses TOML configuration files:

# IMPORTANT: the top-level key is `mcp_servers` rather than `mcpServers`.
[mcp_servers.claude-context]
command = "npx"
args = ["@zilliz/claude-context-mcp@latest"]
env = { "OPENAI_API_KEY" = "your-openai-api-key", "MILVUS_TOKEN" = "your-zilliz-cloud-api-key" }
# Optional: override the default 10s startup timeout
startup_timeout_ms = 20000
```

3. Save the file and restart Codex CLI to apply the changes.
