Proof of Commitment MCP server

Check how risky your npm, PyPI, Cargo and Go packages are before you install them.

Security For it and development Security

Proof of Commitment is a helper that scores software packages on how safe they look, based on who publishes them and how they are maintained. It works with npm (JavaScript), PyPI (Python), Cargo (Rust) and Go packages. It is handy if you install packages for a project and want to know which ones carry extra risk.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Proof of Commitment, a service that checks software packages for risk. Once it is connected, you can ask your AI about a package and it will look up the answer for you.

What this MCP server does

You ask your AI something like which of these packages are risky. Your AI sends the package names to this helper. The helper talks to the Proof of Commitment service, which looks at signals like how many people can publish the package, how often it is updated, and whether it has been involved in an attack. The service sends back a risk score and a short label for each package. Your AI shows you the results in the chat.

Flow diagram: you ask your AI “Are axios, zod and chalk safe to install?”, the Proof of Commitment MCP server connects it to Proof of Commitment, and you get back risk label and score per package.

Try asking your AI

“Check the risk of axios, zod and chalk”
“Which of these npm packages are critical”
“Is litellm safe to use”
“Score the packages in my package.json”

What it gives back to you

You get a short table or list in the chat. Each package shows a risk label like CRITICAL or OK, a score, how many publishers it has, and how many times it is downloaded each week. If a package has been in a known attack, that is shown too.
