MeshDNS is live — MCP-native service registry

[KontractKoder]

MeshDNS is now live 🚀

https://meshdns.onrender.com — a free, public service registry built for the MCP ecosystem.

What it does

Register any MCP server by name, capabilities, and health endpoint. MeshDNS continuously probes every server and surfaces the healthiest ones when clients resolve by capability. Think "consul for MCP" — one binary, zero config.

How it works

# Register your MCP server
curl -X POST https://meshdns.onrender.com/v0/servers \
  -H "Content-Type: application/json" \
  -d '{
    "name": "my-browser-tool",
    "server_url": "https://my-tool.xyz/mcp",
    "health_url": "https://my-tool.xyz/health",
    "capabilities": ["tools", "prompts"]
  }'

# Resolve the healthiest servers for a capability
curl https://meshdns.onrender.com/v0/resolve?capability=tools

What is this actually for?

MCP agents need to find each other. Right now every integration is hardcoded URLs and manual discovery. MeshDNS lets servers self-register and clients resolve by capability — building blocks for an agent mesh.

Roadmap

The discussions board is the roadmap:

• Ideas — what should MeshDNS do next?
• Show and tell — what MCP servers are you registering?
• Q\u0026A — ask anything

Issues are for bugs, discussions are for direction. Welcome aboard.
