Feedback Synthesis MCP server

Feedback Synthesis MCP

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.

<!-- mcp-name: io.github.sapph1re/feedback-synthesis-mcp -->

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.

Quick Start

Install:

pip install feedback-synthesis-mcp

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

export EVM_PRIVATE_KEY=your_private_key_here

Add to Claude Desktop — edit ~/Library/Application Support/Claude/claudedesktopconfig.json:

{
  "mcpServers": {
    "feedback-synthesis-mcp": {
      "command": "feedback-synthesis-mcp",
      "env": {
        "EVM_PRIVATE_KEY": "your_private_key_here"
      }
    }
  }
}

Add to Cursor — edit .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "feedback-synthesis-mcp": {
      "command": "feedback-synthesis-mcp",
      "env": {
        "EVM_PRIVATE_KEY": "your_private_key_here"
      }
    }
  }
}

Restart your client. You now have four customer intelligence tools available.

Payment

This MCP uses x402 micropayments on Base mainnet (USDC). You need:

1. An EVM wallet with USDC on Base mainnet
2. The wallet's private key set as EVMPRIVATEKEY

Each call costs $0.01–$0.05 USDC. Payments are made automatically — no subscriptions, no API keys.

Shortened. The full README is on GitHub.
