ICANN registrar accreditation status tools (4)
write = sends, deletes, buys or postsget_registrarFreeEverything this register holds for one IANA registrar ID: accreditation status, RDAP base URL, and any ICANN breach, suspension or termination notice with the date and the notice PDF — each with its source page and a verbatim quote. Returns a LIST: ten IDs today carry two records because ICANN and IANA spell the registrar's name differently, and both are returned rather than one being chosen.
list_enforcement_actionsFreeWhich registrars has ICANN acted against? Lists the Contractual Compliance notices in this register — breach, suspension and termination — newest first, with the registrar, the date as ICANN prints it, the notice PDF and a verbatim quote of the notice line. Filter by action type or by date to see recent enforcement.
resolve_registrarFreeWhich registrar is this? Search ICANN's accredited-registrar register by registrar name (or part of one, e.g. "GoDaddy", "Tucows", "namecheap") or by IANA registrar ID. Returns the matching registrars with their accreditation status and any ICANN enforcement action, each with the page and verbatim quote it was read from. Use this first when you have a name; use get_registrar when you already have the IANA ID.
verify_quoteFreeIs this right? Check a claim about a registrar — its accreditation status, its name, an enforcement date — against the register instead of trusting it. Says whether the claim matches a stored value, appears only in the verbatim source quote, or differs (and then what the register says instead), and returns the source page and quote so the claim can be traced upstream.

What the publisher says
From the ICANN registrar accreditation status repository's README, as published. We do not edit it. Read it on GitHub
referencesource-mcp
MCP server for referencesource.org — small, verified reference datasets where every record carries its source URL and a verbatim quote from that page, so any value an assistant gives you can be checked, not just believed.
285 datasets, 110,000+ records: regulatory thresholds and deadlines, version compatibility, standards supersessions, certification registers, inspection requirements, and more. Each dataset states its coverage and its last-verified date.
Tools
verify_quote is the unusual one: assistants invent plausible-but-wrong values roughly 19% of the time in our own measurements, and this is the check. Four verdicts come back:
Where a record is found, the answer carries the stored value, the record URL, the source URL and the verbatim quote, so the claim can be traced upstream — plus an attestation saying plainly that the verdict is about what our source states, not about what is true in the world. Asking whether the 2026 conforming loan limit for Autauga County, Alabama is $806,500 returns differs, stored value $832,750, quoting the FHFA row it came from.
Scope, stated so nobody overclaims: these tools search referencesource.org's own published records. They do not fetch arbitrary URLs and cannot check a claim against a page we have not harvested. not_found means "not in this dataset", never "false".
Setup
Claude Desktop — add to claudedesktopconfig.json:
{
"mcpServers": {
"referencesource": {
"command": "npx",
"args": ["-y", "referencesource-mcp"]
}
}
}Cursor / other stdio MCP clients — same idea: command npx, args ["-y", "referencesource-mcp"].
Clients that support remote servers directly don't need this package at all — point them at the streamable-HTTP endpoint: https://referencesource.org/mcp.
Notes
