Overview

AI-generated overview

Remote MCP server that reports published licence facts for popular Hugging Face datasets, including declared licences, licence files and source datasets.

What you can do
  • Look up licence facts for one indexed Hugging Face dataset: declared licence, where it was declared, recorded source datasets, detected licence files and a signal.
  • List popular indexed Hugging Face datasets by download count, optionally filtered by signal, task tag and declared licence ID, returning up to 50 results.
When to use it
Useful when choosing or auditing Hugging Face datasets and you want a quick read on their declared licences, licence files and source datasets before using them.
Requirements
Remote streamable HTTP endpoint; no authentication, environment variables or headers are declared. Network access to the endpoint is needed.
Before you install
Results are licence facts reported by the dataset and its declared sources, not legal advice and not a grant of permission to use a dataset; verify licensing yourself before relying on it. Coverage is limited to the site's published index of popular datasets.

Installation

In SourceWeft

  1. Open Dataset licence facts in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/uk.datalicense%2Fdataset-licence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

dataset_licence

Retrieve published licence facts for one Hugging Face dataset in this site's index: declared licence, where it was declared, recorded source datasets, detected licence files and a signal. Signal values: permissive = permissive or share-alike licence reported; restrictive = use restrictions reported; conflict = possible licence conflict; unclear = insufficient or unrecognised licence information. These signals do not establish permission to use a dataset. Licence facts reported by the dataset and its declared sources. Not legal advice, and not a grant of permission to use the dataset.

find_datasets

List popular Hugging Face datasets from the published index, ordered by download count from highest to lowest. Optionally filter by signal, task tag and declared licence ID; all supplied filters must match. Returns up to 50 results. Signal values: permissive = permissive or share-alike licence reported; restrictive = use restrictions reported; conflict = possible licence conflict; unclear = insufficient or unrecognised licence information. These signals do not establish permission to use a dataset. Licence facts reported by the dataset and its declared sources. Not legal advice, and not a grant of permission to use the dataset.
