🚀 Quick Start

Prerequisites

Python 3.8 or higher
Claude Desktop or Claude Code

Installation

Clone the repository:

git clone https://github.com/yourusername/API_Manager_MCPServer.git cd API_Manager_MCPServer

Install dependencies:

pip install -r requirements.txt

Configure for Claude Desktop:

Add to your Claude Desktop configuration file (claude_desktop_config.json):

{ "mcpServers": { "api-manager": { "command": "python", "args": ["/path/to/API_Manager_MCPServer/api_manager.py"], "env": {} } } }

Configure for Claude Code:

Add to your Claude Code MCP settings:

{ "mcp": { "servers": { "api-manager": { "command": "python", "args": ["/path/to/API_Manager_MCPServer/api_manager.py"] } } } }

Basic Usage

Once configured, you can use the API Manager through Claude with natural language:

"List my API keys" "Add a new OpenAI API key" "Search for Discord keys" "Show statistics about my API keys" "Create a backup of my environment file"

📖 Detailed Usage

Available Commands

🔍 Query Commands

list_api_keys - List all API keys with categories

show_values: Show actual values (default: false)
category: Filter by specific category

get_api_key - Get a specific API key by name

key_name: Name of the key to retrieve

search_api_keys - Search for API keys by name or category

query: Search term
show_values: Show actual values (default: false)

list_categories - List all categories with counts

📝 Management Commands

add_api_key - Add or update an API key

key_name: Name of the API key
value: The API key value

delete_api_key - Delete an API key

key_name: Name of the key to delete

🛠️ Utility Commands

backup_env_file - Create timestamped backup

get_stats - Show detailed statistics

export_keys - Export keys in JSON or ENV format

format: "json" or "env" (default: json)
include_values: Include actual values (default: false)

help - Show comprehensive help

Command Line Options

python api_manager.py --help python api_manager.py --version python api_manager.py --env-file /custom/path/.env python api_manager.py --log-level DEBUG

Environment File Location

By default, API keys are stored in:

~/.config/api_manager/.env

You can specify a custom location using:

Command line: --env-file /path/to/.env
Environment variable: API_MANAGER_ENV_FILE

🔧 Configuration

Environment File Format

# API Manager Environment File # Created on 2024-01-01 12:00:00 # AI Services ANTHROPIC_API_KEY=sk-ant-1234567890abcdef OPENAI_API_KEY=sk-1234567890abcdef # Database Services SUPABASE_API_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9 # Communication DISCORD_BOT_TOKEN=ODcyNzM0NjI5NjU2MjE3NjAw

Security Best Practices

File Permissions: The environment file is automatically created with secure permissions (600)
Backups: Always create backups before making changes
Value Masking: Use show_values=false when listing keys
Logging: Monitor the log file for any suspicious activity
Access Control: Limit access to the environment file location

🧪 Testing

Run the test suite:

# Install test dependencies pip install pytest pytest-asyncio pytest-cov # Run tests pytest tests/ # Run with coverage pytest tests/ --cov=api_manager --cov-report=html

📊 Monitoring and Logs

The API Manager creates detailed logs in api_manager.log:

# View recent activity tail -f api_manager.log # Search for specific operations grep "Tool called" api_manager.log
