Nothing to run from here
Devtools is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
MCP server with 5 offline developer tools: UUID, timestamp, unit conversion, JSON tools and QR code.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http devtools-mcp-2 https://pianam.cn/devtools-mcp/mcp
# 2 — ask your agent for something these tools do
# generate_uuid, convert_timestamp, convert_unit and 4 more
Devtools costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http devtools-mcp-2 https://pianam.cn/devtools-mcp/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

生成 UUID（通用唯一识别码）。支持 v4 随机 UUID（默认）和 v5 命名空间 UUID（SHA-1 确定性生成，需提供 namespace 和 name）。count 可一次生成多个（1~1000）。namespace 支持预定义名 dns/url/oid/x500 或完整 UUID 字符串。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| version | string | no | UUID 版本，"v4"（默认，随机）或 "v5"（命名空间确定性） |
| count | integer | no | 生成数量，1~1000，默认 1 |
| namespace | no | v5 必填，命名空间，可传 "dns"/"url"/"oid"/"x500" 或完整 UUID 字符串 | |
| name | no | v5 必填，命名用的名称字符串，如域名、URL 等 |
时间戳双向转换，时区统一北京时间(UTC+8)。传入 Unix 时间戳（整数秒或毫秒，自动识别；也接受数字字符串）返回 ISO 8601 北京时间字符串；传入日期/时间字符串（如 2026-09-05、2026-09-05 10:30:00、2026-09-05T10:30:00+08:00）返回 Unix 秒/毫秒时间戳；不传 value 返回当前时间的两种格式。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| value | no | Unix 时间戳（秒/毫秒，整数或数字字符串，自动区分）， 或日期时间字符串（ISO 8601、YYYY-MM-DD、YYYY/MM/DD HH:MM 等）； 不传或传空字符串则返回当前北京时间 | |
| to | string | no | 转换方向提示，"iso"（默认，转北京时间字符串）或 "unix"（转时间戳）； 实际方向按 value 类型自动判断 |
单位换算，支持四类：长度(m/km/cm/mm/mile/foot/inch，含毫米/厘米/英里/英尺/英寸)、重量(kg/g/mg/t/lb/oz，含克/磅/盎司)、温度(c/f/k，摄氏度/华氏度/开尔文，自动做偏移换算)、数据存储(B/KB/MB/GB/TB/PB，按1024二进制换算)。不支持的单位或跨类别换算（如米换算成千克）会返回清晰错误。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| value | number | yes | 待换算的数值 |
| from_unit | string | yes | 源单位，如 "km"、"lb"、"f"、"GB" |
| to_unit | string | yes | 目标单位，如 "mile"、"kg"、"c"、"MB" |
JSON 字符串处理。action 支持：format（美化缩进2格，中文不转义）、minify（压缩为单行去空白）、validate（仅校验合法性，非法时返回错误行号、列号、位置指针和上下文片段）。输入 data 必须是字符串。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| data | string | yes | JSON 格式的字符串 |
| action | string | no | "format"（默认，美化缩进2格）、"minify"（压缩）、 "validate"（校验合法性） |
生成二维码。默认 format='svg' 返回 SVG 矢量图字符串（纯标准库生成，可直接保存为 .svg 文件，AI agent 可直接写文件）；format='png' 时返回 PNG 图片的 base64 编码和 data URI（需服务器安装 Pillow，未安装会返回提示）。content 支持 URL、纯文本、WiFi 配置（如 WIFI:T:WPA;S:网络名;P:密码;;）等任意字符串，上限 2000 字节。CPU 密集，走线程池不阻塞事件循环。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| content | string | yes | 要编码的内容，支持 URL、纯文本、WiFi 字符串等，不能为空 |
| format | string | no | "svg"（默认，返回 SVG 文本）或 "png"（返回 base64，需 Pillow） |
查询 npm 包的最新版本信息。输入 npm 包名（如 react、vue、express、@vue/cli），返回最新版本号 latest_version、该版本发布时间 published_at（UTC ISO 8601）、包描述 description、开源协议 license，以及主页/仓库地址等。数据源优先官方 registry.npmjs.org，失败自动兜底淘宝镜像 registry.npmmirror.com（国内更快）。包不存在返回明确的 404 提示。网络 I/O 走线程池不阻塞事件循环。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| package | string | yes | npm 包名，如 "react"、"vue"、"express"、"@vue/cli" |
DNS 域名解析（DoH，JSON API）。输入域名 name（如 baidu.com、www.qq.com）和记录类型 type（A 默认/AAAA/CNAME/MX/TXT），返回解析记录列表（每条含 name、type、ttl、data；MX 数据为 优先级+邮件交换主机，TXT 为文本记录）。数据源优先阿里 DoH（dns.alidns.com，国内快），失败自动兜底 Cloudflare DoH。域名不存在返回 NXDOMAIN 提示；域名存在但无该类型记录时返回空列表并附说明。网络 I/O 走线程池不阻塞事件循环。
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | 要解析的域名，如 "baidu.com"、"www.qq.com"（不含 http:// 和路径） |
| type | string | no | 记录类型，"A"（默认，IPv4）/ "AAAA"（IPv6）/ "CNAME"（别名）/ "MX"（邮件交换）/ "TXT"（文本记录） |

ATool-list grade · score 96 / 100
Release 1.0.1 · scanned 10 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

Score vectorthreat 100 → client 96
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Devtools can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
