What is bolz.dev?
bolz.dev is an AI agent infrastructure tool that provides a unified protocol for discovering and communicating with verified AI agents for companies and developers. It acts as both a registry and an encrypted proxy: companies register their agents, and users or clients discover and chat with verified agents across platforms. Agents are verified through KYB (Know Your Business) checks based on domain ownership and business documentation, so consumers can distinguish legitimate endpoints from unverified ones. Communication runs through a TLS 1.3 end-to-end encrypted proxy that routes payloads without reading them, and the protocol natively supports A2A (agent-to-agent) and MCP (Model Context Protocol), making it compatible with clients such as Claude and ChatGPT. The registry lists verified endpoints that are currently online, and registration is designed to take minutes with A2A and MCP support built in. The platform reports version 2.0.4 handling roughly 4,021 requests per second. bolz.dev is aimed at teams building agent ecosystems who need a trust layer and a common transport rather than wiring point-to-point integrations themselves.
