Tools

7 tools: 7 read-only, 0 change data, 0 high risk (delete, pay, send or run code).

read-only

Only reads or looks things up. Safe for an agent to call on its own.

changes data

Creates, edits or sends something. Worth a person's approval the first time.

high risk

Can delete, pay, send on your behalf or run code. Hard or impossible to undo.

Connecting costs an agent about 2,004 tokens of tool definitions and a 625 ms handshake.

• read-onlyanalyze_traceAnalyze a whole CAN trace of a UDS diagnostic or flash session and say what went wrong. Accepts candump logs, Vector ASC, PEAK TRC (1.x/2.x), SavvyCAN or python-can CSV pasted as text, and those plus Vector BLF, Wireshark pcap/pcapng (SocketCAN) and ASAM MF4 bus logging uploaded as a file. Reasse...
• read-onlydecode_udsDecode a UDS (ISO 14229-1) PDU from hex: request, positive or negative response. Names the service, sub-function (and suppressPosRsp bit), DID/RID/address fields, and for negative responses the NRC with meaning and typical cause. Unknown SIDs and NRCs are labelled, not rejected.
• read-onlybuild_uds_requestBuild a UDS request as hex with an annotated breakdown. Services: session, ecu_reset, read_did, write_did, security_seed, security_key, tester_present, routine, request_download, transfer_data, transfer_exit, clear_dtc, read_dtc, control_dtc, comm_control, raw. Numeric strings are hex.
• read-onlydecode_isotpReassemble ISO-TP (ISO 15765-2) messages from CAN frames, per CAN id, and decode each as UDS. Reports frame types (SF/FF/CF/FC), flow-control BS/STmin, sequence-number errors, interrupted messages, padding, and N_Bs/N_Cr/STmin timing warnings when timestamps (ms) are given. Accepts a frame list o...
• read-onlydecode_dtcConvert a 3-byte UDS DTC to the SAE J2012 style code (P/C/B/U + digits) plus failure type byte, or the reverse ("U0073-00" to hex). With a status byte, explains each of the 8 DTC status bits.
• read-onlyuds_referenceShort UDS reference with ISO 14229-1 clause pointers (paraphrased). Topics: a service ID (0x27) or name, an NRC (0x78 or "nrc 78"), a DID (F190) or RID (FF00), timing (p2, p2*, s3), sessions, security (0x27 vs 0x29), reprogramming_sequence. Unknown topics return a topic list.
• read-onlyudslib_integrationPlan how to integrate the UDSLib C stack (ISO 14229 UDS server/client for embedded ECUs): which repo files to take, Kconfig/config hints, an init skeleton, the closest example, and the license terms (free noncommercial / commercial). UDSLib speaks ISO-TP over CAN/CAN-FD; DoIP is not supported.

Levels are automated estimates from each tool's public name, description and annotations, and can be wrong. Descriptions as the server publishes them.

Badge

Live: status, days reachable, the tokens its tool list costs an agent. For a README:

[![7Maps](https://7it.co.il/7maps/badge/mcp.udslib.com/mcp.svg)](https://7it.co.il/7maps/s/mcp.udslib.com/mcp)

Other styles: add ?style=uptime (30-day uptime), ?style=stars (agents’ rating) or ?style=verified (owner mark) to the image address, or ?style=top (shows "top 10%" when the server ranks in the top tenth of its category by days answering; otherwise the standard badge).

Is this badge genuine? Anyone can check what a genuine badge for this server says right now: /7maps/verify/badge?server=mcp.udslib.com%2Fmcp (add the same &style= for another style).

Own this server? Verify that it is yours.

Status widget

A live status card for a status page, docs or a dashboard: current status, the 30-day strip, uptime and handshake time.

Script (renders where it is placed, in its own shadow DOM):

<script src="https://7it.co.il/7maps/widget/mcp.udslib.com/mcp.js" async></script>

Or an iframe:

<iframe src="https://7it.co.il/7maps/widget/mcp.udslib.com/mcp" title="7Maps status" width="360" height="176" style="border:0;max-width:100%" loading="lazy"></iframe>

The widget is drawn only from 7it.co.il. Is a status shown elsewhere genuine? Check it: /7maps/verify/badge?server=mcp.udslib.com%2Fmcp.

Add ?theme=light or ?theme=dark to either address (default: follows the visitor's setting). Refreshed every 5 minutes. Open the card · script.

For AI agents

Before connecting, an agent can ask 7Maps for this server's full condition, every tool's risk level and what changed since a person approved it: the road_conditions, watch and route tools on https://7it.co.il/7maps/mcp, paid per call in USDC via x402. About 7Maps.
