Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

This one needs environment variables set before it will start: DATAVILLE_API_KEY (Dataville API key from https://app.dataville.com/api-keys), DATAVILLE_API_BASE_URL (API base URL; defaults to https://api.dataville.com). The author declared them in the registry entry; get the values from the project itself.

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.

dataville

list_dataville_sources

List the data sources available through the search_dataville tool.

search_dataville

Query one of Dataville’s data sources (see list_dataville_sources for valid names) with a keyword string. Use it for facts that should come from a real source — company filings, papers, package metadata, nutrition, census figures — rather than from memory.

Dataville — questions

Answers built from our own checks of this server.

What can Dataville do?

It exposes 2 tools, read directly from the server on our last check. Among them: list_dataville_sources, search_dataville. 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 Dataville working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 36 of 36 checks got a reply (100.0%), average response time 415 ms. The bar chart above shows every period we have measured.

How do I connect Dataville?

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 Dataville need an API key?

No. Dataville 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 Dataville?

It answers our handshake in 415 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Dataville?

The npm package @dataville/dataville-mcp was installed 696 times in the last week. Week over week that is +4269%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Dataville open source?

Yes — it is published under the MIT licence, written in TypeScript and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
