referencesource.org is an MCP server with 4 tools an agent can call, among them get_record, list_datasets, search_records. It answers at https://referencesource.org/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 11 September 2026; the last check, on 22 October 2026, succeeded.
Verified reference data; each record carries its source URL and quote. verify_quote checks claims.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_record | Fetch one record by id — for example, look up a FIPS 140 certificate's status, a state's boiler inspection rules, or a county's loan limit. Returns the full record with its source URL and verbatim source quote. Record ids appear in search_r Inputs: dataset_slug, record_id |
list_datasets | What reference datasets are available? Lists every published dataset with its title, record count, last-verified date and a one-sentence summary. Covers regulatory thresholds, version compatibility, certification registers, licensing rules Inputs: query, full |
search_records | Look up a specific record — search by state name, chemical, certificate number, product name or any keyword. Searches one dataset's records (case-insensitive substring match across all fields). Returns up to 20 matching records, each with i Inputs: dataset_slug, query |
verify_quote | Is this value actually right? Check a claimed fact against a published record instead of trusting it. Reports whether the claim matches the record's stored value (exact, case-insensitive or normalised — the match type is named), whether it Inputs: dataset_slug, claimed_value, record_id, field |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://referencesource.org/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: io.github.joelp22-maker. Endpoint host: referencesource.org. ARD identifier: urn:air:io.github.joelp22-maker:mcp:referencesource.
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.
