Show HN: MCP server that checks if your project idea exists

https://github.com/mnemox-ai/idea-reality-mcp
2•mnemoxai•1h ago
I built an MCP server that reality-checks project ideas against GitHub, Hacker News, npm, PyPI, and Product Hunt before you start coding.

v0.3 adds a 3-stage keyword extraction pipeline: - Stage A: Stopword filtering (removes noise like "a tool that can") - Stage B: Intent anchoring (maps vague terms to searchable keywords) - Stage C: Synonym expansion + Chinese-to-English term mapping (150+ terms across 15 domains)

Before: Chinese input "寵物預約看診 app" → searched raw Chinese → garbage results After: Same input → "pet appointment veterinary booking app" → relevant results

Other stats: - 204 tests, 93% keyword extraction accuracy - Quick mode (GitHub + HN) ~2s, Deep mode (5 sources parallel) ~3-4s - Zero config: `uvx idea-reality-mcp` - Works with Claude Desktop, Cursor, any MCP client

Built with Python + FastMCP + httpx async. MIT licensed.
