}Check if a product idea already exists before building it. Use when users discuss new project ideas, ask about competition, market saturation, or whether something has been built before. Trigger phrases: "has anyone built", "does this exist", "check competition", "is this idea original", "有沒有人做過", "市場上有類似的嗎", "幫我查這個點子"
Idea Reality Mcp is an MCP (Model Context Protocol) server that automatically scans GitHub, npm, PyPI, Hacker News, Product Hunt, and Stack Overflow to check if a startup or app idea already exists. It returns a 0–100 reality score with evidence, trend detection, and pivot suggestions, allowing AI agents to decide whether to build, pivot, or abandon the idea before writing code. It is intended for developers and AI agents starting new projects.
Install the server via uvx idea-reality-mcp, then add it to your MCP client. For example, in Claude Code run claude mcp add idea-reality -- uvx idea-reality-mcp. Then ask your agent: “Before I start building, check if this already exists: [your idea]”. The agent calls the idea_check tool with idea_text (required) and optional depth parameter ("quick" or "deep"). A REST API is also available at https://idea-reality-mcp.onrender.com/api/check with no API key required.
In quick mode it scans GitHub repositories and Hacker News discussions. Deep mode adds npm, PyPI, Product Hunt launches, and Stack Overflow questions.
The server runs automatically inside your AI agent without manual effort. It returns a numerical score, evidence, and pivot suggestions rather than a list of links, and it aggregates data from six specialized sources.
No, the basic version is free and requires no API key. For higher GitHub API rate limits you can set the `GITHUB_TOKEN` environment variable, and for Product Hunt deep mode you can set `PRODUCTHUNT_TOKEN`.
The reality score is a 0–100 value derived from weighted sub-scores from each source (e.g., GitHub repos 60% in quick mode). If a source is unavailable, its weight is redistributed automatically.
Idea Reality Mcp supports Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Smithery, and Docker. It can be installed via `uvx` or through Smithery’s remote option.
