Nothing serious here today

Today is the operative word: we check TSUNAGI///Matrix — MAPPING every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

smg2
smg2_compare
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.
smg2_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.
smg2_read
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.
propose
propose_rfkorr
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.
propose_ve
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.
about
about_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.
bin
read_bin
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.
log
read_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.

TSUNAGI///Matrix — MAPPING — questions

Answers built from our own checks of this server.

What can TSUNAGI///Matrix — MAPPING do?
It exposes 8 tools, read directly from the server on our last check. Among them: about_matrix, propose_rfkorr, propose_ve, read_bin, read_log, smg2_compare and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is TSUNAGI///Matrix — MAPPING mostly used for?
Its tools cluster around smg2 and propose. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is TSUNAGI///Matrix — MAPPING working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 97 ms. The bar chart above shows every period we have measured.
How do I connect TSUNAGI///Matrix — MAPPING?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does TSUNAGI///Matrix — MAPPING need an API key?
No. TSUNAGI///Matrix — MAPPING completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is TSUNAGI///Matrix — MAPPING?
It answers our handshake in 97 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use TSUNAGI///Matrix — MAPPING?
The npm package matrix-tsunagi was installed 412 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is TSUNAGI///Matrix — MAPPING open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at matrix-mcp.tsunagi.app, which runs on its operator's own terms.
