LlamaCloud MCP Server

A MCP server connecting to multiple managed indexes on LlamaCloud

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

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

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

{
  "mcpServers": {
    "llamacloud": {
      "command": "node",
      "args": [
        "/path/to/llamacloud/build/index.js",
        "--index",
        "10k-SEC-Tesla",
        "--description",
        "10k SEC documents from 2023 for Tesla",
        "--index",
        "10k-SEC-Apple",
        "--description",
        "10k SEC documents from 2023 for Apple"
      ],
      "env": {
        "LLAMA_CLOUD_PROJECT_NAME": "<YOUR_PROJECT_NAME>",
        "LLAMA_CLOUD_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}

Tool Definition Format

You can define multiple tools by providing pairs of --index and --description arguments. Each tool definition follows this format:

--index "IndexName" --description "Description text"

For example:

node build/index.js --index "10k-SEC-Tesla" --description "10k SEC documents from 2023 for Tesla" --index "10k-SEC-Apple" --description "10k SEC documents from 2023 for Apple"

This will create two tools:

1. get_information_10k_sec_tesla - For querying the 10k-SEC-Tesla index
2. get_information_10k_sec_apple - For querying the 10k-SEC-Apple index

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

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