Ask your assistant who would buy.
The free preview runs inside ChatGPT, Claude, Cursor and anything else that speaks MCP. Give it a company's website and it says what the company sells, names its competitors and buyer segments, counts the companies that match, shows five that could buy, and drafts the first emails.
In ChatGPT
GTM for One is in ChatGPT's app directory. The preview opens as a card in the chat and fills in step by step.
In ChatGPT, open Apps, search for GTM for One, and connect it.
Then just ask. No account needed.
As an MCP server
For Claude, Claude Code, Cursor, VS Code and other MCP clients. Add this URL. There is no key and no sign-in.
https://www.gtmforone.com/mcp
Claude and ChatGPT show the preview as a card; other clients get the same results as text.
Add it to your client
Claude
On claude.ai or the desktop app: open Settings, then Connectors, and choose Add custom connector. Name it GTM for One and paste the URL.
Claude Code
Run this once in your terminal.
claude mcp add --transport http gtm-for-one https://www.gtmforone.com/mcp
Cursor
Add this to ~/.cursor/mcp.json, or under Settings, then MCP.
{
"mcpServers": {
"gtm-for-one": {
"url": "https://www.gtmforone.com/mcp"
}
}
}VS Code
Add this to .vscode/mcp.json in your project.
{
"servers": {
"gtm-for-one": {
"type": "http",
"url": "https://www.gtmforone.com/mcp"
}
}
}Anything else
Any client that connects to a remote MCP server over HTTP. Paste the URL. There is no key and no sign-in.
Then ask
- Who would buy from acme.com?
- Who are acme.com's main competitors?
- Draft a first cold email for acme.com.
What it will not do
- It never shows email addresses and never sends anything. It reads public websites and saves nothing to your account.
- A new website takes up to a minute. One someone has already previewed comes back straight away.
- New websites are limited each day so the preview stays free. A website someone has already previewed never counts.
