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 an

3 read · 0 write · 1 destructive. Blast radius: 1 tool can delete or overwrite — an agent that can be talked into calling a tool can be talked into calling this one.
| Tool | Risk | Description |
|---|---|---|
cancel_navigation | read | Cancel any currently active navigation task. |
clear_costmaps | destructive | Clear navigation costmaps to remove stale obstacle information. |
get_robot_pose | read | Get the current pose (position and orientation) of the robot. |
undock_robot | read | Undock the robot from a charging station or dock. |

Questions
What is the Nav2 MCP server?
MCP server that provides tools and resources to control and monitor robots using Nav2.
What tools does Nav2 expose?
4 in total: 3 read-only, 0 that write, and 1 that can delete or overwrite (clear_costmaps). Every one is listed on this page with its risk.
Is Nav2 safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does Nav2 need?
No credential environment variables were found in its source, so it appears to need none.
How does Nav2 run?
It speaks stdio, so it runs as a local process your client starts. It is published on PyPI as nav2-mcp-server.
How current is this page?
The grade is for one exact copy of the source (8c5bdafa0300), read on 2026-10-07. The repository is watched and re-audited when it changes.
