Documentation

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 -- 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 -- 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 -- npm install presend-api, zero-dependency.
GitHub Action -- checks the dependencies of package.json or requirements.txt in CI (npm and PyPI).
Code examples -- working Python for LangChain, CrewAI, LlamaIndex, OpenAI Agents SDK, Google ADK, and plain REST.
MCP config guides -- copy-paste setup for Claude Desktop, Claude Code, Cursor, and Windsurf, no code required.
Browser 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.
