Bagel MCP server

Bits to atoms.Atoms to bits.

Bagel by Extelligence lets you ask questions about robotics, drone, and IoT data in plain English. Every calculation over your message data is DuckDB SQL, not model guesswork, and Bagel shows you the query so you can audit it.

Is my IMU sensor overheating?

Bagel also has an intelligent edge data reduction pipeline: describe an event and Bagel runs the detection on the robot, keeping the windows that matter and dropping the rest. An MCP server puts all of it in your LLM's hands: Claude Code, Gemini, Cursor, or a fully local model.

Bagel was the first MCP server to ship a real analysis toolkit for robotics data, and it keeps the LLM where it belongs: in front of your logs, never in your robot's control loop.

🥯 Key Features

one sentence becomes an auditable pipeline: previewed before a byte is written, then run once, across a fleet, or standing at the edge.

• Ask in plain language: No deep domain expertise needed.
• Transparent calculations: Deterministic SQL queries. No black-box LLM math.
• Natural-language pipelines: "Keep 10s around every hard brake, drop the rest":

• Broad LLM support: Claude Code, Gemini, Cursor, Codex, and more.
• Dockerized environments: No local dependencies required.
• Extensible capabilities: Bagel can learn new tricks.
• Wide format coverage: Missing your data format? Open a ticket.

🥯 Try it in 60 seconds

No MCP client, no LLM, no config: run the same deterministic checks against a bundled sample log and get a robot-health report card straight to your terminal.

docker run -it --rm ghcr.io/extelligence-ai/bagel/px4:latest demo

The ROS2 images (ros2-kilted, ros2-jazzy, ros2-iron, ros2-humble) run demo the same way, against a lighter bundled sample (px4 is the one that ships with a flight log rich enough to show every check). Point it at your own log with demo /path/to/log (mount it with -v first), or keep reading for the full MCP setup below.
