Common questions

Is Presend dependency checks 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 (1.0.0) reached the registry 35 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.

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.
