I Built 56 Free MCP Servers — Here's a Unified Directory

#mcp #aiagents #opensource #developertools

Building MCP servers for AI agents became my obsession. Three weeks in, I had 56 of them — and a real problem.

The Problem

Every MCP server I built lived in its own GitHub repo. There was no single place to browse them, filter by category, or see which ones had free tiers vs. paid upgrades. For anyone trying to outfit their AI agent with the right tools, discovery was a nightmare.

I needed search. I needed categories. I needed a price tag.

The Solution: AgentPay Labs Product Hub

So I built a unified directory. It's a single-page hub at agentpay-labs-hub that gives you:

Search — type anything, find the right MCP server instantly
Category filters — MCP servers, SaaS tools, services, and more
Direct links — GitHub repos + Stripe buy links for Pro tiers
Stats bar — see total products, categories, and paid plans at a glance

The catalog covers everything from legal research (Court Records MCP, SEC EDGAR MCP, USPTO Patent Search MCP) to developer utilities (PDF Generator, Web Scraper, Database MCP) to AI agent infrastructure (AgentPay Pro, Agent Memory MCP, Agent Cost Tracker MCP).

Highlights
