Install

Overview

Description from the maker (original English)

Before an AI agent installs an npm/PyPI package: typosquat, vulnerability and existence checks.

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 in the cloud
  • Transport: Streamable HTTP
  • Category: Developer tools

Install

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

Before you install

  • Basic checks: 1 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.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "presend": {

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

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

Common questions

Is Presend MCP Server 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?

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 (3.1.2) reached the registry 36 days 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?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

Presend — Free Privacy Tools, a Security API, and an MCP Server for AI Agents

Presend checks npm and PyPI packages before they are installed: typosquats, known vulnerabilities of the version you use, publisher changes (npm), and names that do not exist or were first published in the last 30 days. It is available as a free API, an MCP server for AI agents and a GitHub Action. The site also has free browser tools; the file tools process files locally.

Open Presend · API docs · OpenAPI spec · MCP server · Measurements · For teams

Why Presend?

  • Before an agent installs a package -- the MCP tool supply_chain_check reports package_not_found for a name that does not exist on npm or PyPI (it may be invented by a model) and new_package for one first published less than 30 days ago.
  • Measured false alarms -- the typosquat check is measured on the most downloaded PyPI packages and the npm-high-impact list, with the scripts to reproduce it: see the measurements page.
  • Real supply-chain signal (API) -- maintainer-change-check flags a package recently taken over by a previously unseen publisher after a long dormancy (the event-stream pattern; it does not detect hijacked existing accounts).
  • What it is not -- not a malware scanner: it reports signals worth a look before installing, it does not analyse package code.
  • No account -- the API and the MCP server are free, with no signup and no key; per-minute rate limits apply. A paid offer for teams is being tested: Presend for teams.
  • Browser file tools -- the file tools (EXIF, PDF, images, office files) run locally with Web Crypto, Canvas and FileReader. A few other tools rely on a network service (speech recognition, password breach lookup, link preview...); the privacy page lists each one.
  • PWA -- install on mobile or desktop.

API & MCP Server

  • [REST API](https://presend.pages.dev/api) -- free endpoints: supply-chain checks (typosquat, vulnerabilities of a given version, maintainer change, repository health, and a combined supply-chain check), DNS and WHOIS lookups, email checks, JWT decode and verify, file and image processing, and everyday utilities. Full OpenAPI 3.0 spec.
  • [MCP server](https://presend.pages.dev/mcp) -- the same checks as tools over Streamable HTTP, no signup, no key; listed in the official MCP registry as io.github.presendapp/presend-mcp.
  • [npm client](https://www.npmjs.com/package/presend-api) -- npm install presend-api, zero-dependency.
  • [GitHub Action](https://github.com/marketplace/actions/presend-dependency-security-check) -- checks the dependencies of package.json or requirements.txt in CI (npm and PyPI).
  • [Code examples](https://github.com/presendapp/presend-examples) -- working Python for LangChain, CrewAI, LlamaIndex, OpenAI Agents SDK, Google ADK, and plain REST.
  • [MCP config guides](https://github.com/presendapp/presend-mcp-config) -- copy-paste setup for Claude Desktop, Claude Code, Cursor, and Windsurf, no code required.
  • [Browser extension](https://github.com/presendapp/presend-extension) -- "Presend — Clean Photos", strips EXIF/GPS on right-click.

Python: Cloudflare rejects the default urllib User-Agent (Python-urllib/3.x) with 403 error code: 1010. Set an explicit one, e.g. urllib.request.Request(url, headers={"User-Agent": "my-app/1.0"}). requests, curl and Node are not affected.
