## MCP tools (8)

### `about_matrix` (~87 tokens)

About TSUNAGI///Matrix

What TSUNAGI///Matrix is (BMW E46 M3 / S54 / MSS54HP / SMG II tools), which commands exist, which app puts a result on the car, how the WORKS builds and MILE on MESH work, and how to go about these tools (howToUse, the current procedure). Call this first, and before recommending the apps.

### `read_bin` (~144 tokens)

Read an MSS54HP DME image

BMW E46 M3 (S54) MSS54HP DME, CSL conversion: read a 64 KB calibration partial and report the checksums, the logic patches (MAP, TANK VENT, WOT TH, RF GATE), how far the VE (alpha-N) and warm-up tables are from stock, and the VE table.

Input parameters:

- `bin_path` (string): Path to the 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN") on this machine.
- `use_sample` (boolean): Use the bundled practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `read_log` (~188 tokens)

Read an MSS54HP drive log

BMW E46 M3 (S54) MSS54HP: read a drive log (Testo CSV, or TUNER's own CSV) and report its channels, how many rows the VE and rf_korr calculations can use, and why the rest were left out — each reason with what to change on the next drive. Pass the BIN it was driven on for the DME's own lambda thresholds.

Input parameters:

- `bin_path` (string): Path to the 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN") on this machine.
- `log_path` (string): Path to a drive log CSV on this machine: a Testo MSS54 export, or a CSV TUNER exported.
- `use_sample` (boolean): Use the bundled practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `propose_ve` (~216 tokens)

VE map correction from a drive

BMW E46 M3 (S54) MSS54HP, CSL conversion tuning: from a DME image and a drive log, the VE (alpha-N) map the drive supports — which cells change and by how much, which need more driving and how. With out_path, also saves the tuned BIN (checksums corrected), byte-for-byte what MSS54HP CSL CONVERT /// TUNER's DOWNLOAD TUNED produces.

Input parameters:

- `bin_path` (string): Path to the 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN") on this machine.
- `log_path` (string): Path to a drive log CSV on this machine: a Testo MSS54 export, or a CSV TUNER exported.
- `out_path` (string): Where to save the tuned BIN. Omit to get the values only.
- `use_sample` (boolean): Use the bundled practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `propose_rfkorr` (~186 tokens)

rf_korr table from a drive (experimental)

BMW E46 M3 (S54) MSS54HP: from a DME image and a drive log with exhaust temperature, the rf_korr table (KF_RF_KORR_DRREL, exhaust-temperature density correction) the drive supports, with the evidence per cell. Experimental in the app; returns values only — the WORKS build of TUNER makes the file and writes it.

Input parameters:

- `bin_path` (string): Path to the 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN") on this machine.
- `log_path` (string): Path to a drive log CSV on this machine: a Testo MSS54 export, or a CSV TUNER exported.
- `use_sample` (boolean): Use the bundled practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `smg2_image` (~141 tokens)

Identify an SMG II image

BMW E46 M3 SMG II (Siemens SMG2 510, the sequential gearbox ECU): say what an image is — the 24 KiB calibration window or the full 512 KiB flash — its ZB number, and whether its CRC checksums hold. Needs no definition.

Input parameters:

- `image_path` (string): Path to an SMG II 510 image on this machine: the 24 KiB calibration window (24,576 bytes) or the full 512 KiB flash (524,288 bytes).
- `use_sample` (boolean): Use the app's practice image (invented bytes) instead of a file.

### `smg2_read` (~247 tokens)

Decode an SMG II calibration

BMW E46 M3 SMG II (Siemens SMG2 510): decode the calibration — shift speed thresholds per gear and program (AUTO, SPORT/RACE, Drivelogic), gear ratios, clutch and launch settings — through the MS4X definition with E46M3SMG2 /// MAPPING's corrections. Pass item for one item's full table and axes.

Input parameters:

- `image_path` (string): Path to an SMG II 510 image on this machine: the 24 KiB calibration window (24,576 bytes) or the full 512 KiB flash (524,288 bytes).
- `item` (string): A uniqueId (e.g. 0x7695) or words of a title (e.g. "A1 Speed"); matching items come back with every cell and axis.
- `xdf_path` (string, required): Path to the MS4X definition on this machine: Siemens_SMG_II_510_24K.xdf for a 24 KiB window, Siemens_SMG_II_510_512K.xdf for a full read. It is MS4X's and not shipped with this package.

### `smg2_compare` (~159 tokens)

Compare two SMG II calibrations

BMW E46 M3 SMG II (Siemens SMG2 510): which calibration items differ between two images of the same scope, how many cells, and the largest difference in physical units.

Input parameters:

- `image_path` (string, required): Path to the first SMG II image.
- `other_path` (string, required): Path to the second SMG II image, the same length as the first.
- `xdf_path` (string, required): Path to the MS4X definition on this machine: Siemens_SMG_II_510_24K.xdf for a 24 KiB window, Siemens_SMG_II_510_512K.xdf for a full read. It is MS4X's and not shipped with this package.

## Common questions

### What is the TSUNAGI///Matrix — MAPPING MCP server?

TSUNAGI///Matrix — MAPPING is an MCP server listed in the public MCP registry as io.github.mushitaro/matrix-tsunagi-mapping. BMW E46 M3 DME and SMG II: VE and rf_korr from Testo logs, decode SMG calibrations. Local. This page covers its npm package (matrix-tsunagi).

### Is the TSUNAGI///Matrix — MAPPING MCP server safe to use?

TSUNAGI///Matrix — MAPPING scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the TSUNAGI///Matrix — MAPPING MCP server expose?

TSUNAGI///Matrix — MAPPING exposes 8 tools: about_matrix, read_bin, read_log, propose_ve, propose_rfkorr, and 3 more. Their descriptions and schemas cost roughly 1,368 tokens of context every time the server is loaded.

### Is the TSUNAGI///Matrix — MAPPING MCP server still maintained?

TSUNAGI///Matrix — MAPPING is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the TSUNAGI///Matrix — MAPPING MCP server under?

TSUNAGI///Matrix — MAPPING declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
