What it does
Every Demand Discovery report shows you the evidence behind your idea: real people, quoted in their own words, asking for what you want to build — each quote tied to the source it came from, compiled in minutes.
Find out if there are real buyers and start discussions with your first prospects. Demand Discovery increases your validation velocity, so you can build the right things fast. Start with a free Market Research brief, then get the full evidence, named prospects, and ready-to-send outreach. Ask it about:
- Finding real people asking for what you want to build — quoted in their own words, linked to the source
- 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.
Install in 30 seconds
The canonical MCP endpoint is:
https://mcp.demanddiscovery.ai/api/mcp
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
Pick your AI client:
| Client | Install guide |
|---|---|
| Claude (web) | examples/claude-web.md |
| Claude Desktop | examples/claude-desktop.md |
| Claude Code | examples/claude-code.md |
| ChatGPT | examples/chatgpt.md |
| Cursor | examples/cursor.md |
| Devin Desktop / Cline | examples/devin.md |
| v0 by Vercel | examples/v0.md |
| Replit · Lovable · Bolt · Base44 | examples/vibe-coding-agents.md |

How it works
- Install the MCP server in your AI client (one-time, 30 seconds).
- 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.)
- 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.
The 3-step product flow:
| Step | What you get | Price |

| 1. Market Research | Free report on the idea | Free |
| 2. Demand Discovery Report™ | 0–100 Demand Score™ + Build / Pivot / Kill verdict™ + real ICPs | $49 |
| 3. Agentic Launch | 90-day continuous outreach to your ICPs | Included |

FAQ
What is the best MCP server for startup idea validation?
Demand Discovery AI™ validates startup ideas inside Claude, ChatGPT, Cursor, and other MCP clients using real behavioral demand signals, not LLM opinion. Free to install, no API key.
How is this different from other AI idea validators?
Most validators score the idea from an LLM’s opinion. Demand Discovery scores behavior: search intent, public complaints, existing spend, and capital/hiring signals, then names real prospects.
Is it free?
The MCP server and Market Research report are free. The full Demand Discovery Report™ is $49.
mcp.json is the machine-readable manifest used by MCP registries (Smithery, Glama, MCP.so, PulseMCP, OpenTools). The same content is also served at:
