I've spent the last few weeks building coinopai-mcp — a paid crypto intelligence MCP server — and one question kept coming up: where do you actually list and sell an MCP server?
The MCP ecosystem has thousands of servers but most are hobby projects. The reason is simple: until recently, there was no way to get paid. Here's what the landscape actually looks like in May 2026.
The Free Directories (Great for Visibility, Zero Revenue)
- mcp.so — Largest listing count, instant submission, ranks by GitHub stars
- Smithery — Editorial review, hosted installs, default recommendation for paid clients
- PulseMCP — Launch-day visibility if your server is newsworthy
- Glama — Curated directory with security scanning
These are worth listing on for discovery, but they don't pay.
The Paid Platforms (Where Money Actually Changes Hands)
1. MCP Marketplace — The Most Complete Stack
- Revenue split: 85/15 (you keep 85%)
- Payments: Stripe Connect with automatic payouts
- Features: License key SDKs for Python and TypeScript, creator analytics dashboard, one-click install for buyers
- Size: 5,800+ servers, 1,000+ developers
- Best for: Anyone who wants a Stripe-native experience without building billing infrastructure
2. x402 + Your Own Infrastructure
- Model: HTTP-native micropayments, agents pay per API call in USDC
- Status: 3.3M transactions in the last 30 days, average transaction value $0.46
- Momentum: Just moved to the Linux Foundation. Visa, Stripe, Google, AWS, and Microsoft are founding members. AWS Bedrock AgentCore now integrates x402 natively.
- Best for: Technical founders who want full control over pricing and don't mind running their own server
This is what I built coinopai-mcp on — agents pay $0.01-$0.05 per call in USDC on Base mainnet.
3. MCP Hive — The Newcomer
- Model: Pay-per-invocation for MCP servers
- Status: Early stage, small user base but growing
- Best for: Early adopters willing to bet on a new platform
4. Apify MCP — The Web Scraping Niche
- Revenue split: 80/20
- Community: 36K+ developers, $500K+ monthly payouts
- Caveat: Heavily focused on web scraping and automation actors. If your MCP server isn't about data extraction, the fit is awkward.
5. MuleRun Creator Studio — The Full-Stack Bet
- Revenue split: ~100% to creators
- Bonuses: $100 launch bonus + up to $10,000 based on agent adoption
- Infrastructure: They host, handle LLM costs, and distribute across iPhone Siri, Discord, Telegram
- Status: Still in beta, some billing quirks reported
- Best for: Builders who want to package their MCP server as a full product without touching infrastructure
My Take
If you're shipping an MCP server today, here's my recommended order:
- List on all free directories (mcp.so, Smithery, PulseMCP) — zero friction, instant visibility
-
Pick one paid platform based on your tolerance for infrastructure:
- Want zero devops? → MCP Marketplace
- Want full control? → x402 + self-hosted
- Want product packaging? → MuleRun Creator Studio
- Cross-list everywhere — MCP servers are interoperable across Claude, Cursor, Claude Code, Windsurf. More listings = more surface area.
The payment infrastructure is finally catching up to the protocol. If you've been sitting on an MCP server because you couldn't figure out how to charge for it, the path is clearer than it's ever been.
