Overview

Description from the maker (original English)

Read-only SQL querying + schema introspection over Postgres & SQLite, with a gated write mode.

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.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Databases & datasets
  • You need to fill in: DB_CONN_default

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: DB_CONN_default, DB_WRITABLE

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "sql": {
      "command": "npx",
      "args": [
        "-y",
        "@abhishekmcp/sql"
      ],
      "env": {
        "DB_CONN_default": "your-value",
        "DB_WRITABLE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add sql --env DB_CONN_default=your-value --env DB_WRITABLE=your-value -- npx -y @abhishekmcp/sql

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "sql": {
      "command": "npx",
      "args": [
        "-y",
        "@abhishekmcp/sql"
      ],
      "env": {
        "DB_CONN_default": "your-value",
        "DB_WRITABLE": "your-value"
      }
    }
  }
}

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": {
    "sql": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@abhishekmcp/sql"
      ],
      "env": {
        "DB_CONN_default": "your-value",
        "DB_WRITABLE": "your-value"
      }
    }
  }
}

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.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

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

Values you fill in

  • DB_CONN_default secret env
    Connection URL for the 'default' connection (postgres://… or sqlite:/abs/path). Additional connections use DB_CONN_ . Carries credentials — treated as secret.
  • DB_WRITABLE env
    Set to 1 or true to enable the write tools (execute, execute_script).

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

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is SQL safe?

It passed 1 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?

You need to fill in: DB_CONN_default

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

🧰 mcp-suite

A collection of [Model Context Protocol](https://modelcontextprotocol.io) servers, built in TypeScript.

Each server lives in its own folder under servers/ and publishes to npm as an independent package, while sharing tooling through an npm workspace. Connect them to any MCP client — Claude Desktop, Claude Code, Cursor, and more.

Quickstart

git clone https://github.com/Abhishekkumar2021/mcp-suite.git

cd mcp-suite npm install # installs deps for every workspace npm run build # builds every server

Install

Every server ships through every common channel. For the Claude Code plugin, add the marketplace once — /plugin marketplace add Abhishekkumar2021/mcp-suite — then install per the table. See each server's README for full config.

notes defaults to ~/notes; files requires FS_ROOTS (the directories it may touch). MCPB

bundles install via Claude Desktop → Settings → Extensions.

Connecting to a client

Each server's README has full configuration instructions. As an example, to use the notes server with Claude Code:

claude mcp add notes --env NOTES_DIR=$HOME/notes -- node "$(pwd)/servers/notes/dist/index.js"

Or with Claude Desktop (claude_desktop_config.json):

{

"mcpServers": { "notes": { "command": "node", "args": ["/absolute/path/to/mcp-suite/servers/notes/dist/index.js"], "env": { "NOTES_DIR": "/absolute/path/to/your/notes" } } } }

Architecture & conventions

A few principles hold across every server:

  • Pure-JS/WASM by default; native only when genuinely required. Servers run via npx/MCPB on any machine, so portable pure-JS/WebAssembly is strongly preferred and a native dependency is used only when genuinely required (gated + documented). In practice these servers are dependency-light: notes uses MiniSearch + WebAssembly embeddings, sql uses the sql.js WASM SQLite engine, and files uses fast-glob instead of ripgrep. npm audit stays clean.
  • Sandbox-first, layered design. Each server keeps a thin index.ts (tool registration only) over focused modules, with a single security boundary every path must pass through (realpath-containment, symlink-escape rejection, atomic writes).
  • Token-efficient by default. Pagination, head/tail/section reads, snippets, and compact graph refs keep tool output small.
  • Automated, hands-off releases. A GitHub Release tagged -v publishes to npm (with provenance), the official MCP registry, and attaches an MCPB bundle — all via OIDC, no secrets.
  • Tested in CI. Each server ships a committed node:test suite (unit + integration/security) run on every push.

Development

This is an npm workspaces monorepo.

npm install                      # install all workspace dependencies (run once at the root)

npm run build # build every server npm run build -w servers/notes # build a single server npm test --workspaces --if-present # run each server's test suite npm run clean # remove all build output

Adding a new server

  1. Create servers/ / with its own package.json (unique npm name) and a tsconfig.json that extends: "../../tsconfig.base.json".
  2. Put source in servers/ /src/.
  3. Run npm install at the root so the workspace picks it up.
  4. Add a row to the Servers table above.

All servers follow the naming standard (@abhishekmcp/ ). See CONTRIBUTING.md for detailed guidelines.

Publishing

Releases are automated. Cutting a GitHub Release tagged -v triggers publish.yml, which — authenticated entirely via GitHub OIDC (no NPM_TOKEN) — publishes the package to npm with provenance, registers it on the official MCP registry, and builds + attaches the MCPB bundle to the release.

# bump servers/<name>/package.json, commit, then:

gh release create -v --title " v " --notes "…"
