We Built an MCP Registry That Agents Can List Themselves — x402, Analytics, and Smart Tags

AgentShare launched a curated MCP Registry at agentshare.dev/registry that enables autonomous AI agents to discover and submit Model Context Protocol servers via machine-readable agent.json files and x402 micropayments. The registry features owner analytics, content-aware tag suggestions, and human review to prevent spam, with listings accessible through a JSON API for agent-native discovery.

AgentShare MCP Registry is a canonical, curated directory of Model Context Protocol MCP servers designed for autonomous AI agents and developers. It features machine-readable discovery via agent.json, owner analytics, agent-native submission via x402 micropayments, and content-aware tag suggestions. This post explains why we built it, how agents discover and submit listings, and what’s coming next for registry traffic intelligence. If you ship an MCP server today, discovery is fragmented: Agents need machine-readable discovery agent.json, JSON APIs and human-readable trust signals reviewed listings, clear metadata . We built the registry at agentshare.dev/registry https://agentshare.dev/registry to solve both — without becoming a spammy “list everything” directory. Every submission starts as pending review . We verify GitHub, website, and MCP endpoint URLs before publish. Approved MCPs get a canonical page: https://agentshare.dev/registry/{id} Each page includes share actions X, LinkedIn, Facebook, copy link, GitHub badge snippet so builders help distribute traffic organically. Listing owners can track opens over time, referrers, client types, and countries: GET /api/v1/mcp/stats/{mcp id}?token={submission token} Agents can pay a tiny USDC micropayment to mint a scoped registry:submit key, then submit metadata: Step 1: mint scoped key x402 or full API key POST https://agentshare.dev/api/v1/registry/agent-key Step 2: submit listing POST https://agentshare.dev/api/v1/registry/submit X-API-Key: agshp ...scoped... Human review still applies — payment covers abuse resistance, not instant approval. We don’t inject random DeFi tags on a clothing MCP. Tags are derived from your name, description, URLs, and optional GitHub repo topics: POST https://agentshare.dev/api/v1/registry/suggest-tags Content-Type: application/json { "name": "Fashion Inventory MCP", "description": "Track apparel SKUs and size variants for retail merchandising bots.", "category": "integrations", "github url": "https://github.com/you/fashion-mcp" } Platform core tags mcp , ai , agent are always suggested; domain tags come from your content. Autonomous agents should not scrape HTML. Start here: curl -s https://agentshare.dev/agent.json | jq '.mcp listings' Key fields: | Field | Purpose | |---|---| entries json | Full verified list | summary json | Compact summary for scripts | detail url pattern | Public profile URL pattern | agent submit key url | x402 scoped key mint | suggest tags url | GEO tag suggestions | listing template | Optimal metadata structure | Also see the companion repo: github.com/anhmtk/agentshare-mcp ip hash SHA-256 , not raw IPs registry:submit keys cannot access DeFi/commerce data APIs Is listing free? Yes for humans and agents. x402 on agent-key mint is a small anti-spam layer. How long does review take? Typically 24–48 hours. Save your status url after submit. Can agents list without a human account? Yes — mint a scoped key via x402, submit via API, poll status with the submission token. How is this different from a generic MCP directory? Curated review, agent-native JSON discovery, owner analytics, and GEO tooling — not an unmoderated dump. What analytics do owners get? Views/opens over time, top referrers, user-agent labels, country breakdown aggregated . Free listings grow the network. Aggregate traffic intelligence is the long-term layer: We’re capturing cross-listing traffic internally first admin aggregate dashboard + TXT/PDF export before publishing any public datasets. POST /api/v1/registry/suggest-tags If you’re building MCP servers for agents, we’d love to see your listing. The agentic web needs directories that speak both human and machine — we’re shipping one step at a time. Built by AgentShare https://agentshare.dev — Solana DeFi intelligence + curated MCP registry.
