ChatGPT with sales superpowers.

ChatGPT doesn't yet support customer-installed MCP servers. The moment OpenAI ships it, TexAu will connect to mcp.texau.com on day one with the same x-api-key flow as every other client. In the meantime, hit our REST API directly from a Custom GPT or use Claude.

60-second connect

Honest about ChatGPT — here's what works today.

ChatGPT does not yet support customer-installed MCP servers. Use Claude Desktop or Cursor for the same TexAu tools today, or call our REST API from a Custom GPT action.

MCP not natively supported yet

ChatGPT does not yet support customer-installed MCP servers. Use Claude Desktop or Cursor for the same TexAu tools today, or call our REST API from a Custom GPT action.

curl -X POST https://v3-api.texau.com/api/v1/email_finding_waterfall \
  -H "x-api-key: $TEXAU_KEY" \

Copy-paste to your assistant

Five prompts that work in ChatGPT out of the box.

Click any prompt to copy. Each runs against the real TexAu tool layer.

  • Prompt 1

    Custom GPT action — find email

    Wire the TexAu REST API into a Custom GPT action. Then ask: "Find the verified email for the VP of Engineering at Ramp."
  • Prompt 2

    Custom GPT action — score leads

    Add the /v1/score endpoint to your Custom GPT. Paste a list of leads and an ICP description; the GPT calls TexAu to score each one.
  • Prompt 3

    Use Claude Desktop instead

    List the TexAu tools you have available. (Run this inside Claude Desktop after the 60-second connect.)
  • Prompt 4

    Use Cursor instead

    For each company in this CSV, find the CTO's email and verify it. (Run this inside Cursor after connecting via MCP.)
  • Prompt 5

    Get notified at launch

    Drop your email at the bottom of this page. We'll send the connect link the moment ChatGPT ships customer MCP install.

Demo video — coming soon

Pattern preview: the AI calls a tool through MCP, the result streams back into the chat. No keys in the message body, no plaintext leakage.

Common issues

Stuck? It's almost always one of these.

  • Issue 1

    Why isn't there a one-line install for ChatGPT?

    OpenAI hasn't shipped customer-installed MCP servers in ChatGPT yet. We're tracking it weekly; the day it ships, this page changes from waitlist to install guide.

  • Issue 2

    Can I use the Apps SDK / Plugins?

    OpenAI Plugins were retired in favor of GPTs. Custom GPT actions can call the TexAu REST API directly — that's the workaround until MCP lands.

  • Issue 3

    I need this in ChatGPT today.

    Closest match by UX is Claude Desktop — conversational chat, full MCP, x-api-key auth, 60-second connect. Cursor and Windsurf cover the GTM engineer path.

Pricing, briefly

The MCP server is free. You pay for what your AI calls.

When ChatGPT MCP ships, pricing will mirror every other client — 50 free credits on signup, then prepaid bundles from $0.020/credit.
