Demand Discovery AI™ — MCP Server

> Behavior over opinion.™ Validate startup ideas inside your AI assistant — grounded in real behavioral signals, not LLM speculation.

Works in ChatGPT, Claude (web & Desktop), Claude Code, Cursor, Devin Desktop, Cline, and v0 by Vercel — and in the vibe-coding platforms Replit, Lovable, Bolt, and Base44. Validate ideas where you build.

This repository contains the public manifest, license, trademark notice, and install instructions for the Demand Discovery AI™ Model Context Protocol (MCP) server.

The server itself is hosted, stateless, and free to use with no API key or signup. Source code for the server is proprietary and not published.

What it does

Most founders are validating interest, not demand. Others score opinions. Demand Discovery measures behavior.

Validate startup ideas inside your AI assistant with evidence, not opinion. Find real people asking for what you want to build, quoted in their own words and linked to the original source. Start with a free market research brief, then get full signal evidence, a Build / Pivot / Kill verdict™, and ready-to-send prospect outreach. Ask it about:

• Validating a startup idea with real demand signals — behavior, not opinions or surveys
• Finding your ICP (Ideal Customer Profile): who wants your idea, and where they are
• Market signals, defensibility, and the Build / Pivot / Kill verdict™
• What to build with AI in 2026
• Running a free Market Research Report for any idea, delivered directly in chat
• The paid $49 Demand Discovery™ Report — which hands you the names of the specific people already acting like they want your idea

It exposes 10 tools — six read-only tools (Q&A, framework explanation, product details, signal explanation, approach comparison, data-source bucket overview) plus four action tools that run the journey end-to-end: the free Market Research report (delivered inline in chat), the $49 Demand Discovery™ Report checkout and status, and the 90-day Agentic Launch kickoff.

The canonical MCP endpoint is:

No API key. No signup. Free to use today.

Claude Desktop, one command:

npx demand-discovery-install

That writes the config for you and you're done — restart Claude Desktop and the tools appear. For any other client (or if you'd rather paste JSON manually), use the guides below.

Claude Code, as a plugin (MCP server + skill):

/plugin marketplace add demand-discovery-ai/mcp
/plugin install demand-discovery@demand-discovery-ai

That registers the MCP server *and* installs a skill you invoke by saying “I have an idea I would like to run through Demand Discovery” (asking “should I build this?” works too) — see `plugins/demand-discovery/`.

Any of 70+ coding agents (Cursor, Codex, OpenCode, and more), one command for the Skill:

npx skills add demand-discovery-ai/mcp

That installs the Demand Discovery Skill into whichever coding agents you use — the Skill carries the server URL and walks your agent through connecting to the hosted MCP (add the MCP connector for your client with the guides below if it isn't connected yet).

Claude (web, paid plans), Claude Desktop, and v0 can also use the same skill as a downloadable .zip — upload it in your client's Skills panel:

https://mcp.demanddiscovery.ai/demand-discovery-skill.zip

How it works

1. Install the MCP server in your AI client (one-time, 30 seconds).

2. Say "I have an idea I would like to run through the Demand Discovery connector." — the agent takes it from there. (Any validation question works too.)

3. Get the free report — the free Market Research report is delivered right in the chat (with a copy emailed to you). When you want real proof, the $49 Demand Discovery™ Report and the 90-day Agentic Launch continue from the same conversation.
