The 80x MCP connector

The 80x MCP connector is a Model Context Protocol server that lets an AI assistant act for 80x inside a conversation (submit a project brief, get the booking link, and read the studio's docs and Fund Stack) without anyone leaving the chat.

What it is

MCP (the Model Context Protocol) is an open standard for connecting AI assistants to tools and data. The 80x connector is a small MCP server: add it once and your assistant gains a handful of 80x tools it can call on your behalf. Three tools act: send an inquiry, return the booking link, read the case studies. The others are read-only. The connector both contacts the studio and reads its docs and tooling directory.

It exists for 80x's warm audience — people who already know the studio and want to act without copy-pasting. Cold discovery is handled by the agent-fillable contact form and the markdown mirrors instead.

The tools

Tools that act

  • `submit_inquiry` — send a project brief to 80x. It posts to the same endpoint the contact form uses, so the brief lands in the founder's inbox and gets a reply within one business day.
  • `book_call` — return the link to book an intro call.
  • `get_case_studies` — read 80x's public case studies so the assistant can describe the work accurately.

Read-only tools

These need no credentials; they fetch public URLs on 80x.ai.

  • `search_docs` — list the 80x docs, optionally scoped to one section, so the assistant can pick a page to read.
  • `read_doc` — read one docs page's raw markdown by path.
  • `query_fund_stack` — read and filter The Fund Stack, 80x's directory of VC tooling.

Add it to Claude Desktop

Today the connector runs locally over stdio, which Claude Desktop supports. Add it to your claude_desktop_config.json:

{
  "mcpServers": {
    "80x": {
      "command": "node",
      "args": ["/path/to/80x-mcp/src/stdio.mjs"]
    }
  }
}

Restart Claude Desktop and the 80x tools appear. submit_inquiry is wired to the live production endpoint, so it works the moment the server runs.

A hosted remote connector

A hosted remote connector (one URL you add in your assistant's settings, with no local install) is on the way. It is not live yet — use the stdio setup above. This page will carry the URL when it ships.

Source

The connector is open source in the 80x GitHub organization: github.com/80x-djh. Point it at a preview deploy by setting the EIGHTYX_SITE_URL environment variable.
