MCP server URL

https://hey.sale/mcp

No API key is needed to create a salesperson. Reading a salesperson's conversations, leads or results requires the website owner's own HeySale API key.

· Developer mode connectors are a beta OpenAI is rolling out by plan; if you do not see the option, your account does not have it yet.
· HeySale is not listed in OpenAI's app directory. Connect it as a custom connector for now.

Or start here, right now

Give us your website address. We read it, build your salesperson, and show her to you before you sign up for anything.

Things to say to ChatGPT

“Add a salesperson to my website.”
“Help this website convert more visitors.”
“Add HeySale to this site.”
“Let visitors ask questions before buying.”
“How is my salesperson doing this week?”

Why this pairing works

The site gets built in minutes; the selling still has to happen after the visitor lands.

HeySale reads the finished site and answers from it — no separate knowledge base to maintain.

Leads arrive with the whole conversation attached, so you know what they actually wanted.

HeySale runs one MCP server for every assistant: https://hey.sale/mcp over Streamable HTTP (remote MCP).
