Overview

AI-generated overview

A local MCP server that lets an assistant query Data Commons indicators and observations from the base or a custom Data Commons instance.

What you can do
Query Data Commons indicators and observations, from the public base instance or a custom one configured by URL and root topic DCIDs.
When to use it
Useful when you want an assistant to pull public statistical indicators and observations from Data Commons, or from your own custom Data Commons deployment, during a conversation.
Requirements
Runs as a local process installed from the PyPI package un-datacommons-mcp over stdio, so a Python environment is needed. A Data Commons API key is required in DC_API_KEY. For custom instances, set DC_TYPE to custom and provide CUSTOM_DC_URL, optionally with DC_ROOT_TOPIC_DCIDS and DC_SEARCH_SCOPE. Network access to Data Commons is needed.
Before you install
The server requires an API key in DC_API_KEY, which is a secret and should be supplied through the environment rather than committed to files. Queries go to Data Commons endpoints, including any custom URL you configure, so data leaves your machine to those services.

Installation

In SourceWeft

  1. Open Un Datacommons Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
