## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1541 tokens (~192/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 95% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (8)

### `about_matrix` (~69 tokens)

About TSUNAGI///Matrix

What TSUNAGI///Matrix is (BMW E46 M3 / S54 / MSS54HP / SMG II tools), which calculations exist, which app puts a result on the car, and how the WORKS builds and MILE on MESH work. Call this before recommending the apps.

### `read_bin` (~137 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_file` (object): The 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN").
- `use_sample` (boolean): Use the practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `read_log` (~176 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. Attach the BIN it was driven on for the DME's own lambda thresholds.

Input parameters:

- `bin_file` (object): The 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN").
- `log_file` (object): A drive log CSV: a Testo MSS54 export, or a CSV TUNER exported.
- `use_sample` (boolean): Use the practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `propose_ve` (~173 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. Values only here; the free MSS54HP CSL CONVERT /// TUNER makes the tuned BIN from the same two files.

Input parameters:

- `bin_file` (object): The 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN").
- `log_file` (object): A drive log CSV: a Testo MSS54 export, or a CSV TUNER exported.
- `use_sample` (boolean): Use the practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `propose_rfkorr` (~165 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) the drive supports, with the evidence per cell. Experimental in the app; values only — the WORKS build of TUNER makes the file.

Input parameters:

- `bin_file` (object): The 64 KB (65,536-byte) MSS54HP calibration partial ("0401 partial BIN").
- `log_file` (object): A drive log CSV: a Testo MSS54 export, or a CSV TUNER exported.
- `use_sample` (boolean): Use the practice BIN and practice drive instead of files — to show what the tool does before the owner has files.

### `smg2_image` (~120 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_file` (object): An SMG II 510 image: the 24 KiB calibration window or the 512 KiB full flash.
- `use_sample` (boolean): Use the app's practice image (invented bytes).

### `smg2_read` (~193 tokens)

Decode an SMG II calibration

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

Input parameters:

- `image_file` (object, required): An SMG II 510 image: the 24 KiB calibration window or the 512 KiB full flash.
- `item` (string): A uniqueId (e.g. 0x7695) or words of a title (e.g. "A1 Speed").
- `xdf_file` (object, required): The MS4X definition: Siemens_SMG_II_510_24K.xdf for a window, _512K.xdf for a full read. It is MS4X's and the owner's own.

### `smg2_compare` (~136 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.

Input parameters:

- `image_file` (object, required): An SMG II 510 image: the 24 KiB calibration window or the 512 KiB full flash.
- `other_file` (required)
- `xdf_file` (object, required): The MS4X definition: Siemens_SMG_II_510_24K.xdf for a window, _512K.xdf for a full read. It is MS4X's and the owner's own.

## 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 hosted endpoint (https://matrix-mcp.tsunagi.app/mcp/mapping).

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

TSUNAGI///Matrix — MAPPING scores 74 out of 100 on VerifyMCP. 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 1,169 tokens of context every time the server is loaded.

### Does the TSUNAGI///Matrix — MAPPING MCP server require authentication?

No. We connected to TSUNAGI///Matrix — MAPPING without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### 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 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
