# 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.
