Nav2 MCP Server
An MCP (Model Context Protocol) server that provides tools and resources to control and monitor Nav2 navigation operations, allowing seamless integration with Nav2-enabled robots through the MCP protocol.

Features
- Navigation control: Navigate to specific poses, follow waypoint sequences, and execute precise robot movements
- Real-time status: Monitor navigation progress, robot pose, and system status with comprehensive feedback
- Costmap management: Clear stale obstacle data and manage navigation costmaps for optimal path planning
- Lifecycle management: Control Nav2 system startup and shutdown for complete system control
- ROS 2 integration: Full compatibility with Nav2 navigation stack and ROS 2 ecosystem
- Async operations: Non-blocking navigation commands with progress monitoring and cancellation support
