humanMCP Marketplace

Think of it as a town square where every stall is independently owned. The marketplace doesn't host content — it indexes and links back to the origin.

{ "mcpServers": { "humanmcp-marketplace": { "type": "http", "url": "https://marketplace.humanmcp.net/mcp" } } }

Any humanMCP instance can join. No account needed — just your domain:

curl -X POST https://marketplace.humanmcp.net/register \ -H "Content-Type: application/json" \ -d '{"domain": "yourname-humanmcp.fly.dev"}'

- Verify it's a real humanMCP (fetches/.well-known/agent.json)
- Index all listings from/listings/feed.json
- Add to crawl schedule (every 6 hours)

Requirements: your server must expose/.well-known/agent.jsonand/listings/feed.json.

Your humanMCP server ↓ Marketplace fetches /.well-known/agent.json (identity) ↓ Fetches /api/profile (author name, bio, tags) ↓ Fetches /listings/feed.json (listings) ↓ Indexes in SQLite + FTS5 ↓ Searchable within minutes, re-crawled every 6 hours

Listings stay on your server. Marketplace keeps a search index only.
