MCP-Ables

Turn any shell command into MCP Server

Why bother coding long MCP servers for every need, when you can just use MCP-Ables?

What is MCP-Ables?

MCP-Ables bridges the gap between command-line tools and AI agents like Claude Code. Write a tiny YAML file describing your shell command, and MCP-Ables automatically generates an MCP (Model Context Protocol) server that AI agents can call.

No Python coding. No complex setup. Just YAML → MCP → AI-callable tools.

Quick Start

Prerequisites

• Python 3.11+
• The command-line tool you want to expose (e.g., nuclei, nmap, kubectl , etc.)

Installation

git clone https://github.com/mfakbar127/MCP-Ables.git
cd MCP-Ables
pip install -r requirements.txt

Usage

1. Create a YAML file describing your tool(s) (see examples below)

2. Run MCP-Ables with a file or directory:

   # Single file
   python mcpables-main.py examples/nuclei.yaml
   
   # Directory (scans recursively for .yaml/.yml files)
   python mcpables-main.py examples/
   

3. The MCP server 'mcpables' is now running with all your tools!

Yaml Exampl - Simple Echo

examples/tools/echo.yaml:

run:
  kind: shell
  cmd: "echo {{message}}"

args:
  message:
    type: string
    description: "Message to echo"
    required: true

Run it:

python mcpables-main.py examples/tools/echo.yaml

Examples

Nuclei Scanner

examples/tools/nuclei.yaml:

run:
  kind: shell
  cmd: "nuclei -c {{concurrency}} -t {{target}} -t {{template_path}}"

args:
  target:
    type: string
    description: "Target URL or IP address to scan (e.g., https://example.com)"
    required: true

  template_path:
    type: string
    description: "Path to Nuclei templates directory (e.g., ~/nuclei-templates/)"
    required: true

Run it:

python mcpables-main.py examples/security-tools.yaml
# Loads 3 tools: nmap_scan, whois_lookup, dig_dns

Directory Example

Organize tools in separate files:

├── curl.yaml     (http_request tool)
└── ...

Run all tools from directory:

python mcpables-main.py examples/tools/

Claude Desktop Integration

Connect MCP-Ables to Claude Desktop so AI can use your tools directly from chat.

Configuration

1. Locate Claude Desktop config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add MCP-Ables server:

{
  "mcpServers": {
    "mcpables": {
      "command": "python",
      "args": [
        "/absolute/path/to/mcpables-main.py",
        "/absolute/path/to/examples/"
      ]
    }
  }
}

3. Restart Claude Desktop - Tools will automatically appear

Configuration Examples

Single file (specific vibe):

{
  "mcpServers": {
    "secops": {
      "command": "python",
      "args": ["/path/to/mcpables-main.py", "/path/to/examples/secops-tools.yaml"]
    }
  }
}

Directory (all tools):

{
  "mcpServers": {
    "mcpables-all": {
      "command": "python",
      "args": ["/path/to/mcpables-main.py", "/path/to/examples/"]
    }
  }
}

Multiple configurations (different vibes):

{
  "mcpServers": {
    "secops": {
      "command": "python",
      "args": ["/path/to/mcpables-main.py", "/path/to/examples/secops-tools.yaml"]
    },
    "devops": {
      "command": "python",
      "args": ["/path/to/mcpables-main.py", "/path/to/examples/devops-tools.yaml"]
    },
    "netops": {
      "command": "python",
      "args": ["/path/to/mcpables-main.py", "/path/to/examples/netops-tools.yaml"]
    }
  }
}

Verify Connection

After restarting Claude Desktop, you can verify the tools are available:

• Type a message asking Claude about available tools
• Tools will appear with names like nuclei_scan, nmap_scan, etc.
• Claude can now execute commands directly!
