mcp-cli-agent 1.2.0

MCP-enabled AI assistant with tool integration

CLI Agent

A powerful, modular command-line interface for interacting with AI models enhanced with Model Context Protocol (MCP) tool integration. Features a centralized architecture that makes it easy to add new LLM providers while providing robust tool integration and subagent management capabilities.

🚀 Features

• Multiple AI Backends: Support for Anthropic Claude, OpenAI GPT, DeepSeek, Google Gemini, OpenRouter, and ollama with easy extensibility
• Hooks System: Powerful workflow automation with security controls - audit commands, block dangerous operations, auto-format code, and integrate with external tools
• MCP Model Server: Expose all AI models as standardized MCP tools with persistent conversations
• Modular Architecture: Provider-model separation with centralized base agent for maximum flexibility
• MCP Server Integration: Connect to multiple MCP servers for extended functionality
• Persistent Conversations: Maintain conversation context across multiple tool calls for each AI model
• Interactive Chat: Real-time conversation with AI models and comprehensive tool access
• Subagent System: Spawn focused subagents for complex tasks with automatic coordination
• Command-Line Tools: Manage MCP servers and query models directly
• Built-in Tools: File operations, bash execution, web fetching, todo management, and task delegation
• Enhanced Tool Display: Full parameter visibility and complete response output (no truncation)

📦 Installation

Option 1: Install from PyPI (Recommended)

pip install mcp-cli-agent

Option 2: Install from Source

1. Clone the repository:

   git clone https://github.com/amranu/cli-agent.git
   cd cli-agent
   

2. Install the package:

⚙️ Configuration

Configure API keys (environment variables):

    # Set environment variables for the providers you want to use
    export OPENAI_API_KEY=your_openai_api_key_here
    export DEEPSEEK_API_KEY=your_deepseek_api_key_here
    export ANTHROPIC_API_KEY=your_anthropic_api_key_here
    export GEMINI_API_KEY=your_gemini_api_key_here
    export OPENROUTER_API_KEY=your_openrouter_api_key_here

    # Start with automatic provider selection
    agent chat
    
    # Or specify a particular provider-model combination
    agent chat --model openai:gpt-4-turbo-preview

Smart Provider Selection: The agent automatically selects a configured provider based on available API keys.

Configuration is automatically saved to ~/.config/cli-agent/config.json and persists across sessions.

Migration from MCP Agent: If you previously used MCP Agent, your configuration will be automatically migrated from ~/.config/mcp-agent/ to ~/.config/cli-agent/ on first run.

🛠️ Usage

Interactive Chat

Start an interactive chat session with your configured AI model and MCP tools:

agent chat --model deepseek:deepseek-chat

MCP Model Server

Start the MCP model server to expose all AI models as standardized MCP tools with persistent conversations:

# Start via stdio transport (recommended for MCP clients)
python mcp_server.py --stdio

# Or start via agent CLI (defaults to stdio)
agent mcp serve
agent mcp serve --stdio  # explicit stdio

# Start with TCP transport (useful for debugging)
python mcp_server.py --tcp --port 3000 --host localhost
agent mcp serve --tcp --port 3000 --host localhost

The model server exposes AI models from 6 providers:

• Anthropic: Claude models
• OpenAI: GPT models
• DeepSeek: Chat and reasoning models
• Gemini: Google's Gemini models
• OpenRouter: Multi-provider access
• Ollama: Local models via Ollama server

MCP Server Management

Add a new MCP server

# Format: name:command:arg1:arg2:...
agent mcp add myserver:node:/path/to/server.js
agent mcp add filesystem:python:-m:mcp.server.stdio:filesystem:--root:.

# Add the AI models server to your MCP configuration
agent mcp add ai-models:python:mcp_server.py:--stdio

List configured servers

agent mcp list

Remove a server

agent mcp remove myserver

Single Query

Ask a one-time question without entering interactive mode:

agent ask "What's the weather like today?"

Model Switching

Switch between different AI models using the provider-model format (configuration persists automatically):

# Provider-model format switching
agent switch anthropic:claude-3.5-sonnet
agent switch openai:gpt-4-turbo-preview
agent switch deepseek:deepseek-chat
agent switch gemini:gemini-2.5-flash

Or use slash commands within interactive chat:

/switch anthropic:claude-3.5-sonnet
/switch openai:gpt-4-turbo-preview
/switch deepseek:deepseek-reasoner
/switch gemini:gemini-2.5-pro

🔧 Configuration

Persistent Configuration System

The agent uses an automatic persistent configuration system that saves settings to ~/.config/cli-agent/config.json:

• API Keys: Set via environment variables
• Model Preferences: Automatically saved when using switch commands
• MCP Servers: Managed through the CLI and persisted across sessions
• Tool Permissions: Configurable with session-based approval system

Environment Variables

Configure the agent through environment variables:

# Anthropic Configuration (required for Claude models)
ANTHROPIC_API_KEY=your_key_here
ANTHROPIC_MODEL=claude-3-5-sonnet-20241022     # optional, defaults to claude-3-5-sonnet-20241022
ANTHROPIC_TEMPERATURE=0.7                      # optional, defaults to 0.7

🔍 Interactive Chat Commands

Within the interactive chat, use these slash commands:

• /help - Show available commands
• /tools - List all available tools
• /clear - Clear conversation history
• /model - Show current model
• /tokens - Show token usage

📚 Examples

Example: Basic File Operations

agent chat --model deepseek:deepseek-chat

In chat:

You: List all files in this directory
You: Read the contents of agent.py
You: Create a new file called hello.py with a simple function

Example: System Operations

In chat:

You: Show me the current directory
You: Run "git status" to check repository status
You: What's the disk usage of this folder?

Example: Subagent Task Delegation

For complex or context-heavy tasks, delegate to focused subagents:

You: /task Analyze all Python files in the src/ directory and create a summary of the class structure and dependencies

You: Can you analyze this large log file and find any error patterns?
     [Agent automatically spawns subagent for file analysis]

Subagents work independently and automatically return results to the main conversation.
