Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account mushitaro for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Read-only local MCP server that inspects BMW E46 M3 MSS54HP DME backups and E46 cluster M35080 EEPROM dumps and reports what they contain.

What you can do: Explain the TSUNAGI///Matrix toolset and the current procedure for using it
Inspect a full 1 MiB MSS54HP DME backup: bootloader per processor, CRC status, program number, remaining CSL conversion work
Compare two DME images and name the differing regions (bootloader, program, calibration, master, slave)
Check a 1 KB M35080 cluster EEPROM read: real chip read, mileage in the secure counter, layout, checksums, VIN copy agreement
Compare two M35080 images by area and report the mileage each reads
When to use it: Useful when you have a BMW E46 M3 DME or instrument cluster backup and want an assistant to verify it, explain its contents, or diff two dumps before deciding on a CSL conversion or cluster swap. It only reads images; the actual backup, conversion and mileage work happens in the separate TSUNAGI apps.
Requirements: Runs locally over stdio via npx (Node.js required). No accounts, API keys, environment variables or headers are declared, and no network access is needed for the analysis. Desktop only.

Before you install

The server never modifies images and sends nothing off the machine, and it does not print the VIN or the DME identity record. Acting on the car, converting, or carrying mileage to a replacement cluster is done in the separate WORKS apps, which require a one-time MILE purchase on MESH; that purchase is a wish on record, not a promise of any release.

Installation

In SourceWeft

Open TSUNAGI///Matrix — MIGRATION in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

matrix-tsunagi-migration

The MIGRATION MCP server of TSUNAGI///Matrix, the BMW E46 M3 tools.

It is the same server as npx -y matrix-tsunagi mcp migration. This package exists so the MCP Registry can list it as io.github.mushitaro/matrix-tsunagi-migration.

The server READS and never changes an image:

boot_backup / boot_compare — a full 1 MiB MSS54HP DME backup, from MSS54HP CSL CONVERT /// BOOT: which bootloader each processor carries, whether its CRC holds, the program number, and what the CSL conversion has left to do.
m35080_read / m35080_compare — a 1 KB E46 cluster M35080 EEPROM backup, from E46 M35080 /// MIGRATION: whether it is a real chip read, the mileage, the checksums, and whether the VIN copies agree.

The VIN and the DME's identity record are never printed. Everything runs on your own machine and nothing is sent. Backing up, converting and carrying a car's true mileage to a replacement cluster are done in the tools' WORKS builds. Those builds are for people who have bought MILE on MESH, a one-time payment.
