# elasticsearch-mcp

An MCP (Model Context Protocol) server for Elasticsearch clusters. Enables AI assistants like Claude to search, analyze, and interact with Elasticsearch through natural language.

[![PyPI version](https://badge.fury.io/py/elasticsearch-mcp.svg)](https://badge.fury.io/py/elasticsearch-mcp)
[![Python 3.10+](https://img.shields.io/badge/python-3.10+-blue.svg)](https://www.python.org/downloads/)
[![License: Apache-2.0](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)

## Features

- **Natural Language Search**: Ask Claude about your data in plain English
- **Index Discovery**: Explore indices, mappings, and field types
- **Search & Aggregations**: Full Query DSL and aggregation support
- **Document Operations**: Read, index, update, and delete documents
- **Data Export**: Export search results to JSON or CSV
- **Knowledge Persistence**: Claude remembers what it learns about your cluster
- **Safety Controls**: Read-only mode, index blocking, result limits
- **Connection Watchdog**: Automatic recovery from hung connections
- **OAuth Integration**: Deploy as a Claude.ai Custom Connector with SSO

## Quick Start

### 1. Install

```bash
pip install elasticsearch-mcp
```

### 2. Configure Claude Desktop

Edit your Claude Desktop config file:

**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "elasticsearch": {
      "command": "elasticsearch-mcp",
      "env": {
        "ES_HOST": "https://your-cluster.es.example.com:9200",
        "ES_API_KEY": "your-api-key",
        "ES_READ_ONLY": "true"
      }
    }
  }
}
```

### 3. Restart Claude Desktop

Quit and reopen Claude Desktop. You'll see a hammer icon indicating tools are available.

### 4. Start Chatting

Ask Claude about your Elasticsearch data:

> "What indices are available?"

> "Search for errors in the logs index from the last hour"

> "Show me the top 10 users by request count"

> "Describe the mappings for the customers index"
