Feedback Synthesis MCP

Synthesize customer feedback from GitHub Issues, Hacker News, and App Store — extract pain points, sentiment trends, and search feedback via x402 micropayments

Customer feedback intelligence for AI agents and developers. Synthesize GitHub Issues, Hacker News threads, and App Store reviews into ranked pain clusters with evidence links. Pay-per-call via x402 micropayments — no signup required.

Stop reading through hundreds of feedback items manually. Feedback Synthesis MCP collects from multiple sources, runs a multi-pass LLM pipeline, and returns ranked pain clusters with impact scores, evidence links, and suggested actions — machine-readable for agents, human-readable for founders.

Set your wallet key(any EVM wallet with USDC on Base mainnet):

export EVM_PRIVATE_KEY=your_private_key_here
