About Feedback Synthesis MCP
Feedback Synthesis MCP is a customer-feedback analysis server for developers and AI agents. It groups GitHub Issues, Hacker News posts, and App Store reviews into ranked pain clusters with evidence and suggested actions.
Key features
- 01Synthesize feedback across sources
- 02Extract pain points from one source
- 03Search cached feedback text
- 04Track sentiment over time
- 05Rank pain clusters with evidence
Use cases
- 01Prioritize recurring issues across products
- 02Review feedback for a GitHub project
- 03Search feedback about a topic
- 04Monitor app review sentiment
MCP support
The MCP server exposes four customer-feedback tools for synthesis, pain-point extraction, search, and sentiment trends. It supports local installation or a hosted Streamable HTTP endpoint, with x402 payments per call.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

|---|---|---|---|
| focus | string | No | Optional focus area to prioritize (e.g. "performance", "onboarding"). |
| since | string | No | Only include feedback after this date (ISO 8601, e.g. "2025-01-01"). |
| sources | array | Yes | List of source configs. Each must have "type" (github_issues, hackernews, appstore) and "target" (e.g. "owner/repo", "product name", app ID). |

Details
From the project READMEFeedback 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": [

}
],
"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:
- An EVM wallet with USDC on Base mainnet
- 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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
