# RAPP

> AI agents anyone can use. Three free, read-only MCP servers: build a single-file AI agent from an idea and run it on the user's data, find one of about 1,700 ready-made agents, or get verified world numbers with a public SHA-256 fingerprint. No account, no API key, nothing stored.

## MCP servers (streamable HTTP, no auth)

- [RAPP Agent Builder](https://rapp-agent-builder.azurewebsites.net/mcp): get_agent_template, check_agent, use_agent_here, find_agents, get_agent_code, share_agent, how_to_run_agent
- [RAR Agent Finder](https://rapp-agent-builder.azurewebsites.net/finder/mcp): find_agents, get_agent_code, use_agent_here, how_to_run_agent
- [DOGG World Check](https://rapp-agent-builder.azurewebsites.net/world/mcp): world_now, fingerprint_text
- [RAPP Domains](https://rapp-agent-builder.azurewebsites.net/domains/mcp): check_domain, register_domain

## Pay per call (x402 v2, USDC)

- GET https://rapp-agent-builder.azurewebsites.net/x402/world: fresh verified world snapshot, $0.001
- POST https://rapp-agent-builder.azurewebsites.net/x402/domains/register?domain=NAME: register an available domain; the 402 response quotes the price; charged only if registration succeeds (raise your x402 client's default $1 per-payment cap first)
