DevTools MCP

Registry namecn.pianam.mcp/devtools-mcp

Install

Overview

Description from the maker (original English)

Developer toolkit: UUID, timestamp, unit conversion, JSON tools, and QR code (SVG). Free.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://mcp.pianam.cn/devtools-mcp/mcp

Run this in your terminal

claude mcp add --transport http devtools https://mcp.pianam.cn/devtools-mcp/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "devtools": {
      "url": "https://mcp.pianam.cn/devtools-mcp/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "devtools": {
      "type": "http",
      "url": "https://mcp.pianam.cn/devtools-mcp/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

We have not read this server’s tool list yet; we check endpoints in rotation.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 7, 2026

Compared with others in Otheri

  • More stars than 0% of the other 32623 servers in this category
  • Published to the registry more recently than 33% of the other 32623 servers in this category
  • Basic checks equal to or better than 30% of the other 32623 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is DevTools MCP safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Developer Toolkit MCP

Five high-frequency developer utilities as MCP tools — UUID generation, timestamp conversion (Beijing time), unit conversion, JSON formatting/validation, and QR-code generation. Everything runs locally; four of the five tools use only the Python standard library.

  • Try it in 30 seconds: a free public MCP endpoint is already running — just paste the URL into your MCP client (no install, no API key).
  • Or self-host: a tiny FastMCP server, no external API calls, deterministic and privacy-safe.

⚡ Use the hosted endpoint (no setup)

https://mcp.pianam.cn/devtools-mcp/mcp

Transport: Streamable HTTP (MCP 2025-03-26 compatible). No authentication required.

🔌 Client configuration

Add this to your MCP client's mcpServers configuration (Claude Desktop, Cursor, Cline, Cherry Studio, etc.):

{

"mcpServers": { "devtools": { "type": "http", "url": "https://mcp.pianam.cn/devtools-mcp/mcp" } } }

Clients that do not accept "type": "http" accept the same entry with just "url".

🧰 Tools

| Tool | Parameters | Returns | |

---|---|---| | generate_uuid(version="v4", count=1, namespace=null, name=null) | version: v4 random (default) or v5 namespaced SHA-1. count: 1–1000. For v5: namespace (dns/url/oid/x500 or a full UUID) + name. | List of UUID strings (v5 is deterministic for the same namespace+name). | | convert_timestamp(value=null, to="iso") | value: Unix timestamp in seconds or milliseconds (auto-detected, int or numeric string) or a date/time string (2026-09-05, 2026-09-05 10:30:00, ISO 8601…). Omit for "now". | ISO 8601 Beijing-time string + readable form + Unix seconds/milliseconds + weekday; or the reverse conversion from a date string. All times use Asia/Shanghai (UTC+8). | | convert_unit(value, from_unit, to_unit) | Numeric value and units across length (m/km/cm/mm/mile/foot/inch…), weight (kg/g/mg/t/lb/oz…), temperature (c/f/k, with offset), data storage (B/KB/MB/GB/TB/PB, binary 1024). Chinese unit names also accepted. | Converted result plus a readable equation; cross-category conversion (e.g. meters to kilograms) returns a clear error. | | format_json(data, action="format") | data: JSON string. action: format (pretty, 2-space indent, Chinese unescaped) / minify / validate. | Formatted/minified text with length comparison, or a validity verdict; on invalid JSON returns error line/column, a position pointer and a context snippet. | | generate_qr(content, format="svg") | content: URL/text/WiFi string (≤ 2000 bytes). format: svg (default, vector) or png. | SVG markup string (save as .svg; an agent can write the file directly) or, for PNG, base64 + data URI (PNG requires Pillow). |

Examples
  • "生成 5 个 UUID" / "给域名 example.com 生成一个 v5 UUID"
  • "把时间戳 1788000000 转成北京时间" / "2026-10-01 09:00 的 Unix 时间戳是多少"
  • "10 英里等于多少公里" / "98.6 华氏度转摄氏度" / "1 GB 等于多少 MB"
  • "帮我美化这段 JSON 并检查有没有语法错误"
  • "把 https://example.com 生成二维码"

📡 Dependencies & privacy

  • generate_uuid, convert_timestamp, convert_unit, format_json use only the Python standard library.
  • generate_qr uses the pure-Python qrcode package with its SVG path image factory — SVG output needs no Pillow/native deps. PNG output is optional and requires Pillow.
  • Zero network calls, zero API keys — fully deterministic and safe for sensitive data.

🐢 Self-hosting

git clone https://github.com/boy-373/devtools-mcp.git

cd devtools-mcp pip install -r requirements.txt python server.py

listens on 127.0.0.1:8000 by default; override with:

MCP_HOST=0.0.0.0 MCP_PORT=9000 python server.py

behind a reverse proxy, allow your public hostname:

MCP_ALLOWED_HOSTS="your-domain.com,your-domain.com:*" python server.py

Then point your MCP client at http://127.0.0.1:8000/mcp.

With uv:

uv venv && uv pip install -r requirements.txt

uv run python server.py

🗂️ Files

  • devtools_server.py — the MCP server: all five tools and FastMCP definitions.
  • server.py — standalone Streamable HTTP entry point (serves the MCP app at /mcp).
