# gcloud MCP Server

A high-performance Model Context Protocol (MCP) server that provides intelligent access to Google Cloud CLI (gcloud) commands and documentation.

## Features

- **Fast Command Search**: O(k) trie-based lookups for exact command paths
- **Intelligent Text Search**: Inverted index with TF-IDF scoring for description searches  
- **4 Powerful Tools**: Search commands, get details, search flags, suggest commands
- **High Performance**: <50ms queries, <2s startup, <500MB memory
- **Comprehensive Coverage**: 5,907 commands and 12,374 flags indexed

## Performance Metrics ✅

- **Loading Time**: 1,775ms (target: <2,000ms)
- **Memory Usage**: 99MB (target: <500MB) 
- **Search Speed**: 30ms (target: <50ms)
- **Trie Lookups**: 0ms (target: <5ms)

## Installation

### For Claude Code Users (Primary Method)

The easiest way to install is using the Claude Code MCP command:

```bash
claude mcp add gcloud-mcp -s user -- npx gcloud-mcp
```

This will automatically:
1. Use the npm package via npx (no global install needed)
2. Add the server to your Claude Code configuration
3. Make it available in all your Claude Code sessions

### Alternative: Manual Installation

#### Global Installation
```bash
npm install -g gcloud-mcp
```

Then add to your Claude Desktop configuration:

```json
{
  "mcpServers": {
    "gcloud-mcp": {
      "command": "gcloud-mcp",
      "env": {}
    }
  }
}
```

#### Local Installation
```bash
npm install gcloud-mcp
```

Then add to your Claude Desktop configuration:

```json
{
  "mcpServers": {
    "gcloud-mcp": {
      "command": "npx",
      "args": ["gcloud-mcp"],
      "env": {}
    }
  }
}
```

### Prerequisites
- Node.js 18.0.0 or higher

## How It Works

The server includes a comprehensive gcloud command index (gcloud.json) with:
- 5,907 gcloud commands
- 12,374 command flags
- Complete documentation and examples

This data is automatically loaded when the server starts, providing instant access to gcloud CLI information without requiring the gcloud CLI to be installed.

### Direct Usage
```bash
node build/index.js
```

## MCP Tools

### 1. search_commands
Search for gcloud commands using keywords or descriptions.

**Parameters:**
- `query` (string): Search term
- `maxResults` (number, optional): Maximum results (default: 10)
- `searchType` (string, optional): 'exact', 'prefix', 'description', 'all' (default: 'all')
- `includeHidden` (boolean, optional): Include hidden commands (default: false)

**Example:**
```typescript
{
  "query": "compute instances create",
  "maxResults": 5,
  "searchType": "all"
}
```

### 2. get_command_details
Get comprehensive information about a specific gcloud command.

**Parameters:**
- `commandPath` (string): Full command path (e.g., "compute instances create")

**Example:**
```typescript
{
  "commandPath": "compute instances create"
}
```

### 3. search_flags
Search for gcloud flags by name, description, or functionality.

**Parameters:**
- `query` (string): Search term
- `maxResults` (number, optional): Maximum results (default: 20)
- `commandContext` (string, optional): Filter by command context
- `flagType` (string, optional): Filter by flag type
- `includeGlobal` (boolean, optional): Include global flags (default: true)

**Example:**
```typescript
{
  "query": "zone",
  "maxResults": 10,
  "commandContext": "compute"
}
```

### 4. suggest_command
Get AI-powered command suggestions based on user intent.

**Parameters:**
- `userIntent` (string): Description of what the user wants to accomplish
- `maxSuggestions` (number, optional): Maximum suggestions (default: 5)
- `includeFlags` (boolean, optional): Include relevant flags (default: true)

**Example:**
```typescript
{
  "userIntent": "create a virtual machine in us-west1",
  "maxSuggestions": 3,
  "includeFlags": true
}
```

## MCP Resources

### gcloud://server/stats
Server performance and indexing statistics in JSON format.

### gcloud://cli/version  
gcloud CLI version and indexing information in plain text.

## Architecture

### Data Structures
- **CommandTrie**: O(k) command path lookups using trie data structure
- **InvertedIndex**: Full-text search with TF-IDF scoring for descriptions
- **FlagsMap**: Fast flag lookups by name

### Core Components
- **GcloudDataLoader**: Loads and indexes 35.7MB gcloud.json file
- **Search Tools**: 4 specialized MCP tools for different search patterns
- **Performance Optimizations**: Efficient memory usage and fast query responses
