Look up toll free numbers from your AI assistant

I'm Bill Quimby. If you use Claude or another AI assistant, it can look up toll free numbers here directly: what a number is today, which RespOrg holds it, and its history. It can look things up, but it can't change anything or sign you up. Every answer links back to the number's page here.

Add it to Claude

In Claude, open Customize, then Connectors. Click + Add, then Add custom connector, name it Resporgs.com, paste this address, and choose No sign in:

https://resporgs.com/mcp

On a Claude Team or Enterprise plan, an owner adds it once under Organization settings, then Connectors.

Other assistants

Any assistant that lets you add an MCP server by its address can use the same one, such as Perplexity on its paid plans. Developers can add it in Cursor, VS Code or Gemini CLI.

What it answers

• Check a number: any toll free number, by digits or by spelling, what it is today, who holds it, and its history page here.
• A number's history: who has held a toll free number and when, from Resporgs.com's records.

Good to know

Answers come from the toll free registry's data, and each answer says which month. Lookups are one number at a time, with daily limits. My privacy page explains what I keep.
