Who it is for
Sales and go-to-market teams that already use Common Room for prospecting and account research.
Overview
What Common Room does
Common Room brings buyer intelligence into ChatGPT as a research surface. Accounts and contacts can be looked up, buying signals surfaced, and activity history read through ordinary questions.
Prospect list building is part of it. New companies can be found by industry, headcount, technology in use, or location, and contacts filtered or sorted by segment, role, lead score, or recorded website visits. Results draw on CRM fields, scores, enrichment data, and signals held in the connected account.
Worked examples in the listing include researching a named company and drafting an approach to it, looking up a single contact by email address, finding economic buyers inside a saved segment, and identifying pricing page visitors from the past week. Six skills are named, covering account and contact research, prospecting, call preparation, outreach drafting, and a weekly briefing.
What stands out
Prospect filters extend to technology in use and recent website visits alongside the usual firmographic criteria.

Where Common Room is listed
Common Room ships this on both marketplaces: Common Room is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
Common Room publishes 5 tools to Claude, a deliberately narrow surface; only 22.3% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Sales & Marketing publishes 18, so this one sits 13 tools below its bucket's median, 85th of 94.
It falls in the 4-6 tools band, which holds 16.2% of the Claude directory.
Common Room publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Common Room carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
In the publisher's words
How Common Room describes it
Embed complete buyer intelligence directly within Claude. Research accounts and contacts, surface buying signals, and browse activity history - all through natural language. Build prospect lists of net-new companies by industry, size, tech stack, or location. Filter and sort contacts by segment, role, lead score, or website visits. Every result is grounded in real context, real prioritization, and real revenue opportunity directly from your CRM fields, scores, enrichment, and signals - so you always know what's actually happening in your accounts.
