Developer tools that don't suck.
AI-native CLI tools for developers and AI agents. Built for the terminal. Powered by MCPMCP (Model Context Protocol) — lets AI assistants like Claude and GPT use CLI tools directly. Think of it as plugins for AI..
Free to start. No account needed. Works with Claude, GPT, Copilot, Cursor, and any MCP-compatible AI.
npm i -g mpx-scan
Four tools. Zero bloat.
Each tool does one thing well. No 200MB Electron apps. No mandatory accounts. Just npm install and go.
Find security holes before hackers do. Headers, SSL, cookies, DNS — scanned in seconds, not hours.
npm i -g mpx-scan
We think Postman is bloated. You probably do too. Test APIs from your terminal in one command.
npm i -g mpx-api
One CLI for SQLite, PostgreSQL, and MySQL. Query, migrate, inspect. No more juggling database GUIs.
npm i -g mpx-db
Your API keys are probably in a git repo somewhere. Find them before someone else does.
npm i -g mpx-secrets-audit
Your AI already knows how to use these.
Every tool is an MCPMCP (Model Context Protocol) — the standard that lets AI assistants discover and use CLI tools directly. No plugins, no integrations — just add to your config. server. Tell your AI "scan this website" and it just works. --json output, --schema discovery, predictable exit codes.
MCP Server Mode
Run mpx-scan mcp and your AI agent can discover and invoke it automatically. Zero integration work.
--json Everything
Every command spits out clean JSON. Pipe it, parse it, feed it to your CI/CD. No regex required.
--schema Discovery
AI agents run --schema to learn the entire API surface. Self-documenting tools that explain themselves.
Composable Pipelines
stdin/stdout, --batch, --quiet. Chain tools together like Unix intended. Your scripts will thank you.

}Why developers choose Mesaplex
We built the tools we wished existed. Then we made them free.
Terminal-native, not terminal-adjacent
No Electron. No browser tabs. No 500MB installs. Just npm install and you're scanning in 10 seconds.
Actually free, not "free"
The free tier solves real problems. No crippled demos, no "upgrade to see results." We're not that kind of company.
No account. No tracking. No BS.
Install and use. That's it. No email verification, no OAuth dance. Your data stays on your machine where it belongs.
