MCP for working with Autosar arxml files

[girishchandranc]

I am happy to announce the new MCP server for autosarfactory. What this means in practice is that when you ask Claude Code (or any MCP-compatible AI assistant) to help you create or modify AUTOSAR arxml files,. It will help generate the python script using autosarfactory apis and you could use it to generate the arxml files. The MCP supports both system level as well as ecuc configuration.

The MCP server exposes the autosarfactory API to AI coding assistants such as Claude Code. It allows an AI agent to query the full API reference, discover element hierarchies, look up enum values, and generate correct autosarfactory Python scripts — all without needing to read source code manually.

You can also optionally feed it AUTOSAR spec PDFs to build a searchable knowledge base, so the agent can look up spec-level details when it needs to.

Setup is straightforward — just add a few lines to your .vscode/mcp.json and you're good to go. Full instructions are in the mcp_server/README.md file.

If you have a chance to use the tooling, I would love to hear if it works well for you or if anything is missing.

Some example prompts to start with:

• Create an AUTOSAR arxml with a sender SWC that sends a uint8 signal over CAN at 500kbps with CAN ID 56
• Can you add one more software component which is reading data from the same provider port
• Give me 10 send signals and 10 receives signals mapped to uinique can frame with unique ids with no data transformers and it shall be mapped to same can controller. And all the signals are send and received by same soiftware component. Also, add the relevant events for data reception. And use one runnable for sending data.
• Can you make autosarfactory to read the sender_can.arxml file and then add a new pport to the software component SenderSWC
• Can you use the new port to use a structure with 2 elements of uint8 and uint6. Send this  over ethernet frame and using someip data transformer
• Add a mode switch communication between 2 software components
• Add someip transformer to the signal vehicleData
• Add E2E transformer to the transformer chain
