# AgentRoot — DNS-based discovery protocol for AI capabilities

> AgentRoot lets any domain declare its AI capabilities — agents, MCP servers, skills, A2A endpoints — using a DNS TXT record and a JSON manifest. No accounts. No API keys. Just DNS and JSON.

## What this site contains

- Public registry of domains that have published `_agentroot.<domain>` TXT records and `.well-known/agentroot.json` manifests
- Protocol specification (DNS TXT format, manifest schema, record types, verification flow)
- CLI, MCP server, REST API, and Web UI for resolving and installing capabilities

## Key documents

- Tools (CLI, MCP, library): https://agentroot.io/docs/tools

## Publishing your domain

1. Add DNS TXT record: `_agentroot.<domain>` IN TXT "v=ar1 manifest=https://<domain>/.well-known/agentroot.json"
2. Host a JSON manifest at `.well-known/agentroot.json` with `{ domain, records: [...] }`
3. Submit at https://agentroot.io/publish (or via API: POST /api/submit)

## Programmatic access
