/What is Attestari MCP?

Attestari MCP exposes Attestari's package verdicts over the Model Context Protocol. An agent can ask about an npm or PyPI package version before installing it and receive the grade, the decision, confirmed findings by reason code and place, and the methodology version and document hash the decision cites.

Notably, a result of 'not examined' is treated as its own answer and is never a signal that a package is safe.

AI-generated listing based on the project's public information. It may contain errors: check the original source.

Opens the chat with the message ready. You choose whether to send it; if it doesn't appear, paste this page's link.

/How to install

You need: Any Claude plan. The free plan allows 1 custom connector; on Team or Enterprise the organisation owner adds it first.

In claude.ai or the Claude app, open "Customize" → "Connectors".

Press "+ Add" and choose "Add custom connector".

Type a name you'll recognise, paste the URL below and press "Continue".

For authentication choose "No sign in", press "Continue" and then "Add".

https://mcp.attestari.ai/mcp

Afterwards: In a chat, press "+" at the bottom left → "Connectors" and turn it on.

You need: A paid ChatGPT account: it may not be available on the free plan. ChatGPT now calls connectors "Plugins".

Go to chatgpt.com/plugins.

Press "+" and choose "Add custom MCP server".

Type a name and a description, and paste the URL below under "Connection".

Don't set up authentication. Accept "I understand and want to continue" and press "Create as a plugin".

https://mcp.attestari.ai/mcp

Afterwards: In a new chat, type @ and pick the plugin.

You need: The Gemini app doesn't support custom connectors yet. It's done with Gemini CLI from the terminal, which needs a Gemini Code Assist license (it no longer has a free tier).

Install Gemini CLI if you don't have it yet.

In the terminal, run the command below.

Open Gemini CLI and type /mcp to check it shows up.

gemini mcp add --transport http -s user attestari 'https://mcp.attestari.ai/mcp'

Afterwards: Ask as usual: Gemini will use the connector when it needs it.

You need: A Grok account. On Grok Business or Enterprise, an admin turns it on first.

Go to grok.com/connectors.

Press "New Connector" and choose "Custom".

Paste the URL below and save.

https://mcp.attestari.ai/mcp

Afterwards: Grok will use the connector whenever your question needs it.
