# LlamaCloud MCP Server

A MCP server connecting to multiple managed indexes on [LlamaCloud](https://cloud.llamaindex.ai/)

This is a TypeScript-based MCP server that creates multiple tools, each connected to a specific managed index on LlamaCloud. Each tool is defined through command-line arguments.

## Features

### Tools

- Creates a separate tool for each index you define
- Each tool provides a `query` parameter to search its specific index
- Auto-generates tool names like `get_information_index_name` based on index names

## Installation

To use with your MCP Client (e.g. Claude Desktop, Windsurf or Cursor), add the following config to your MCP client config:

The `LLAMA_CLOUD_PROJECT_NAME` environment variable is optional and defaults to `Default` if not set.

```json
{
  "mcpServers": {
    "llamacloud": {
      "command": "npx",
      "args": [
        "-y",
        "@llamaindex/mcp-server-llamacloud",
        "--index",
        "10k-SEC-Tesla",
        "--description",
        "10k SEC documents from 2023 for Tesla",
        "--topK",
        "5",
        "--index",
        "10k-SEC-Apple",
        "--description",
        "10k SEC documents from 2023 for Apple"
      ],
      "env": {
        "LLAMA_CLOUD_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}
```

For Claude, the MCP config can be found at:

- On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
- On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

### Tool Definition Format

In the `args` array of the MCP config, you can define multiple tools by providing pairs of `--index` and `--description` arguments. Each pair defines a new tool. You can also optionally specify `--topK` to limit the number of results.

For example:

```bash
--index "10k-SEC-Tesla" --description "10k SEC documents from 2023 for Tesla" --topK 5
```

Adds a tool for the `10k-SEC-Tesla` LlamaCloud index to the MCP server. In this example, it's configured to return the top 5 results.

## Development

Install dependencies:

```bash
npm install
```

Build the server:

```bash
npm run build
```

For development with auto-rebuild:

```bash
npm run watch
```

To use the development version, replace in your MCP config `npx @llamaindex/mcp-server-llamacloud` with `node ./build/index.js`.

### Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:

```bash
npm run inspector
```

The Inspector will provide a URL to access debugging tools in your browser.
