# ROSBag MCP Server

The code is inspired by [ROSBag MCP Server: Analyzing Robot Data with LLMs for Agentic Embodied AI Applications](https://arxiv.org/pdf/2511.03497).

An MCP (Model Context Protocol) server for analyzing ROS and ROS 2 bag files with LLMs. Enables natural language interaction with robotic datasets for debugging, performance evaluation, and extracting insights.

## Features

### Core Data Access & Management
| Tool | Description |
|------|-------------|
| `set_bag_path` | Set path to a rosbag file or directory |
| `list_bags` | List all available rosbag files in directory |
| `bag_info` | Retrieve bag metadata: topics, message counts, duration, time range |
| `get_topic_schema` | Inspect message structure/schema with sample data |

### Message Retrieval
| Tool | Description |
|------|-------------|
| `get_message_at_time` | Get message from a topic at a specific timestamp |
| `get_messages_in_range` | Get all messages from a topic within a time range |
| `search_messages` | Search messages using conditions (regex, equals, near_position, threshold) |

### Data Filtering & Export
| Tool | Description |
|------|-------------|
| `filter_bag` | Create a filtered copy of a bag file by topic, time, or sample rate |
| `export_to_csv` | Export topic data to CSV file for external analysis |

### Domain-Specific Analysis
| Tool | Description |
|------|-------------|
| `analyze_trajectory` | Compute trajectory metrics: total distance, mean/max speeds, position bounds |
| `analyze_lidar_scan` | Analyze LiDAR scans for obstacles, gaps, and statistics |
| `analyze_imu` | Analyze IMU data: acceleration, angular velocity, orientation statistics |
| `analyze_logs` | Parse and analyze ROS logs; filter by level or node |
| `get_tf_tree` | Get TF tree of coordinate frame relationships |
| `get_image_at_time` | Extract camera image at specific time (returns base64 JPEG) |

### Navigation Analysis
