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.

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/claude_desktop_config.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.

Examples

Synthesize feedback from multiple sources

synthesize_feedback(
  sources=[
    {"type": "github_issues", "target": "owner/my-repo", "labels": ["bug", "feature-request"]},
    {"type": "hackernews", "target": "Show HN: MyProduct"}
  ],
  since="2026-01-01T00:00:00Z"
)

Returns:

{
  "job_id": "syn_abc123",
  "status": "completed",
  "summary": "Analyzed 347 feedback items from 2 sources. Found 6 pain clusters.",
  "pain_clusters": [
    {
      "rank": 1,
      "title": "Authentication flow breaks on mobile Safari",
      "severity": "critical",
      "frequency": 23,
      "impact_score": 0.92,
      "description": "Users report inability to complete OAuth login on iOS Safari. Affects onboarding conversion.",
      "evidence": [
        {

          "url": "https://github.com/owner/my-repo/issues/142",
          "snippet": "Login fails silently on Safari 17.2+"
        }
      ],
      "suggested_actions": [
        "Fix Safari WebAuthn polyfill (see issue #142)",
        "Add fallback auth flow for mobile browsers"
      ]
    }
  ]
}

Quick pain points from GitHub Issues

get_pain_points(
  source={"type": "github_issues", "target": "owner/my-repo", "labels": ["bug"]},
  top_n=5
)

Search for specific topics

search_feedback(query="pricing too expensive", sources=["github_issues", "hackernews"])

Track sentiment over time

get_sentiment_trends(
  sources=[{"type": "appstore", "target": "com.example.myapp"}],
  since="2025-10-01T00:00:00Z",
  granularity="weekly"
)

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 EVM_PRIVATE_KEY

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

No payment configured? The server returns a helpful error with setup instructions.

Architecture

This package is a thin MCP client. All processing happens on the hosted backend:

Your Agent / Claude Desktop
        │
        ▼
feedback-synthesis-mcp (this package)
  - MCP tool definitions
  - x402 payment signing
  - Zero business logic
        │ HTTPS + x402
        ▼
Hosted Backend (Railway)
  - Multi-source data collection
  - 3-stage LLM pipeline (Haiku × N + Sonnet × 1)
  - SQLite caching + FTS search
  - x402 payment verification

Server code is private (moat). Thin client is open source.

Direct MCP over HTTP (Streamable HTTP Transport)

Skip the PyPI package for programmatic/agent access using the hosted MCP endpoint directly:

MCP Server URL: https://feedback-synthesis-mcp-production.up.railway.app/mcp/

For MCP clients that support Streamable HTTP transport (Claude Desktop via HTTP, custom agents):

{
  "mcpServers": {
    "feedback-synthesis-mcp": {
      "type": "streamable-http",
      "url": "https://feedback-synthesis-mcp-production.up.railway.app/mcp/"
    }
  }
}

x402 payment is handled automatically by the client SDK. Set EVM_PRIVATE_KEY in your environment.
