Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

domain

domain_provenance

Who runs this domain? Live RDAP lookup: registration date and age, registrar, nameservers, status, whether the registrant is redacted, plus a typosquat check (edit-distance / brand-substring) against high-value brands. A very recently registered domain resembling a bank or big brand is a classic phishing signal — but report it as a signal, not a conclusion.

package

package_provenance

Who publishes this package, and is it a typosquat? Live npm or PyPI lookup: first-publish date and age, release count, latest version, maintainers/author, linked repo, plus a typosquat check against popular package names. Use when an agent is about to install or recommend an unfamiliar dependency.

Databutler Provenance — questions

Answers built from our own checks of this server.

What can Databutler Provenance do?

It exposes 2 tools, read directly from the server on our last check. Among them: domain_provenance, package_provenance. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Databutler Provenance working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 82 of 92 checks got a reply (89.1%), average response time 240 ms. The bar chart above shows every period we have measured.

Is Databutler Provenance still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Databutler Provenance?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Databutler Provenance need an API key?

No. Databutler Provenance completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Databutler Provenance?

It answers our handshake in 240 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
