Package check for coding agents (x402)
Check PyPI/npm packages or a whole lockfile before install: CVEs, typosquats, verdict. 50 free.
What it does
Package check for coding agents (x402) is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
From the publisher's description, Electra Index matched it to one capability: security scanning. That makes it a candidate for tasks such as review pull requests or scan code for vulnerabilities.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

2 tools offered to AI assistants
check_packages· Before your agent runs pip install or npm install, check a package list or a whole lockfile (requirements.txt, poetry.lock, uv.lock, Pipfile.lock, package-lock.json, pnpm-lock.yaml, yarn.lock; one verdict per unique package, with line numbeselftest· Free. Replays the published known-answer set v1 (11 cases) against the live registries and returns score and sha256, so you can verify the check before paying.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
