Bagel MCP server

Bagel is a helper that lets your AI read robot, drone and sensor logs for you. Instead of writing scripts to dig through flight recordings or sensor data, you just ask a question in normal words. It is handy for anyone who works with robots, drones, vehicles or connected devices and has data files piling up.

What this MCP server does

You ask your AI a question about your data, like whether a sensor is overheating. Your AI sends that question to Bagel. Bagel looks at the file, figures out which parts matter, and runs a real database query over the data. It shows you the query it used, so you can check the math yourself. Then you get a plain answer back in the chat, with the numbers behind it.

What you can do with it

• Summarize the metadata of a robot or drone log file
• Find peak values, averages and percentiles in a sensor topic
• Check the correlation between two signals, like current and voltage
• Spot sudden decelerations or other events in a recording
• Keep only the time windows around events you care about and drop the rest
• Read error messages from robot text logs and explain what went wrong
• Run the same check across a whole folder of log files at once

Try asking your AI

• “Summarize the metadata of the ROS2 bag in my data folder”
• “What's the peak z-axis deceleration in the IMU topic, and the running average over 5 seconds?”
• “Every time the drone decelerates harder than -10 m/s squared, keep 10 seconds before and after and drop the rest”
• “Read the ERROR lines from my robot log folder and tell me what went wrong”

What it gives back to you

You get answers in plain language, backed by real numbers: peaks, averages, correlations, counts and short summaries. For event searches, it can also produce trimmed data files that keep only the moments you asked about. It shows the actual query it ran, so you can see how the answer was worked out. Some results can be exported for viewing in tools like Rerun, PlotJuggler or LeRobot.

Who it's for

Robotics, drone and IoT engineers, testers and analysts who have lots of log files and want quick answers without writing scripts.
