Mozilla Data Collective is a remote MCP server that gives an AI agent 3 tools, among them fetch, list_filters, search. It answers at https://mozilladatacollective.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Search the Mozilla Data Collective catalog of ethically sourced AI training datasets.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
fetch | Fetch the full public details of one Mozilla Data Collective dataset by id or slug: description, organization, task, locale, license, format, size, pricing, and its page URL. Inputs: id |
list_filters | List every value the search tool's filters accept: the tasks, locales, licenses and formats present in the catalog, plus the sort and date-range options. Task and license values are abbreviations, so taskLabels and licenseLabels spell them |
search | Search the Mozilla Data Collective catalog of AI training datasets by natural-language query, optionally narrowed by task, language, license, format, price, sample availability or publish date. Returns matching datasets as {id, title, url}; Inputs: query, limit, task, locale, license, format |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mozilladatacollective.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: com.mozilladatacollective. Endpoint host: mozilladatacollective.com. ARD identifier: urn:air:com.mozilladatacollective:mcp:datasets.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
