How It Works

1. The MCP Client analyzes your request and determines which Elasticsearch operations are needed.

2. The MCP server carries out these operations (listing indices, fetching mappings, performing searches).

3. The MCP Client processes the results and presents them in a user-friendly format.

Getting Started

Prerequisites

• An Elasticsearch instance

• Elasticsearch authentication credentials (API key or username/password)

• MCP Client (e.g. Claude Desktop, Cursor)

Installation & Setup

Using the Published NPM Package

[!TIP] The easiest way to use Elasticsearch MCP Server is through the published npm package.

1. **Configure MCP Client** - Open your MCP Client. See the [list of MCP Clients](https://modelcontextprotocol.io/clients), here we are configuring Claude Desktop. - Go to **Settings > Developer > MCP Servers** - Click `Edit Config` and add a new MCP Server with the following configuration: ```json { "mcpServers": { "elasticsearch-mcp": { "command": "npx", "args": [ "-y", "@awesome-ai/elasticsearch-mcp" ], "env": { "ES_HOST": "your-elasticsearch-host", "ES_API_KEY": "your-api-key" } } } } ```

2. **Start a Conversation** - Open a new conversation in your MCP Client. - The MCP server should connect automatically. - You can now ask questions about your Elasticsearch data.

Configuration Options

[!NOTE] You must provide either an API key or both username and password for authentication.

Local Development

[!NOTE] If you want to modify or extend the MCP Server, follow these local development steps.

1. **Use the correct Node.js version** ```bash nvm use ```

2. **Install Dependencies** ```bash npm install ```

3. **Build the Project** ```bash npm run build ```

4. **Run locally in Claude Desktop App** - Open **Claude Desktop App** - Go to **Settings > Developer > MCP Servers** - Click `Edit Config` and add a new MCP Server with the following configuration: ```json { "mcpServers": { "elasticsearch-mcp": { "command": "node", "args": [ "/path/to/your/project/dist/index.js" ], "env": { "ES_HOST": "your-elasticsearch-host", "ES_API_KEY": "your-api-key" } } } } ```

5. **Run locally in Cursor Editor** - Open **Cursor Editor** - Go to **Cursor Settings > MCP** - Click `Add new global MCP Server` and add a new MCP Server with the following configuration: ```json { "mcpServers": { "elasticsearch-mcp": { "command": "node", "args": [ "/path/to/your/project/dist/index.js" ], "env": { "ES_HOST": "your-elasticsearch-host", "ES_API_KEY": "your-api-key" } } } } ```

6. **Debugging with MCP Inspector** ```bash ES_HOST=your-elasticsearch-url ES_API_KEY=your-api-key npm run inspector ``` This will start the MCP Inspector, allowing you to debug and analyze requests. You should see: ```bash Starting MCP inspector... Proxy server listening on port 6277 MCP Inspector is up and running at http://127.0.0.1:6274 ```

Example Queries

[!TIP] Here are some natural language queries you can try with your MCP Client.

Cluster Management

• "What is the health status of my Elasticsearch cluster?"

• "How many active nodes are in my cluster?"

Index Operations

• "What indices do I have in my Elasticsearch cluster?"

• "Create a new index called 'users' with 3 shards and 1 replica."

• "Reindex data from 'old_index' to 'new_index'."

Mapping Management

• "Show me the field mappings for the 'products' index."

• "Add a keyword type field called 'tags' to the 'products' index."

Search & Data Operations

• "Find all orders over $500 from last month."

• "Which products received the most 5-star reviews?"

• "Bulk import these customer records into the 'customers' index."

Template Management

• "Create an index template for logs with pattern 'logs-*'."

• "Show me all my index templates."

• "Delete the 'outdated_template' index template."
