[experimental] Run Model Context Protocol (MCP) server

This command starts an MCP server that exposes mise functionality to AI assistants over stdin/stdout using JSON-RPC protocol.

The MCP server provides access to:

• Installed and available tools
• Task definitions and execution
• Environment variables
• Configuration information
• Task execution via the run_task tool

Resources available:

• mise://tools - List all tools (use ?include_inactive=true to include inactive tools)
• mise://tasks - List all tasks with their configurations
• mise://env - List all environment variables
• mise://config - Show configuration files and project root

Tools available:

• install_tool - Install a tool with an optional version (not yet implemented)
• run_task - Execute a mise task with optional arguments

Note: This is primarily intended for integration with AI assistants like Claude, Cursor, or other tools that support the Model Context Protocol.

Examples:

# Start the MCP server (typically used by AI assistant tools)
$ mise mcp

# Example integration with Claude Desktop (add to claude_desktop_config.json):
{
  "mcpServers": {
    "mise": {
      "command": "mise",
      "args": ["mcp"],
      "env": {
        "MISE_EXPERIMENTAL": "1"
      }
    }
  }
}

# Interactive testing with JSON-RPC commands:
$ echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' | mise mcp

# Resources you can query:
- mise://tools - List active tools
- mise://tools?include_inactive=true - List all installed tools
- mise://tasks - List all tasks
- mise://env - List environment variables
- mise://config - Show configuration info

# Tools available:
- install_tool - Install a tool (not yet implemented)
- run_task - Execute a mise task with optional arguments
  Example: {"task": "build", "args": ["--verbose"]}
