Registry
Curated registry of ACP-compatible agents with authentication.
A must-use for ACP adopters, but its value is tied to protocol adoption. Great for discoverability and security; limited outside the ACP ecosystem.
- Developers building ACP-compatible clients needing agent discovery
- Agent creators seeking a distribution channel with authentication
- Teams wanting a standardized, secure agent catalog
- Open source enthusiasts contributing to the agent ecosystem
- Non-technical users looking for GUI-based agent stores
- Agents that do not support authentication (cannot be listed)
- Users wanting a one-click install marketplace

About Registry
The ACP Registry is a curated directory of agents that implement the Agent Client Protocol (ACP), designed to help developers find and install ACP-compatible agents easily. It only includes agents that support authentication, ensuring a baseline level of security. The registry is open source, hosted on GitHub, and serves as a distribution channel for agent developers. With over 50 agents listed, including popular ones like Cursor, GitHub Copilot, Devin, and Claude Agent, it is a growing ecosystem for coding and general-purpose agents. Developers can browse agents by name, version, and description, and then install them via ACP-compatible clients. The registry is protocol-first, focusing on interoperability and trust, which sets it apart from generic agent marketplaces.
Behind the Verdict
The ACP Registry is a focused solution for developers already in the ACP ecosystem. It offers a curated list of agents that all support authentication, which is a clear security win over open marketplaces. The open-source GitHub model allows community contributions via pull requests, making it easy for agent creators to get listed. However, if you're not using ACP, the registry has no value. It's also heavily weighted toward coding agents, with general-purpose agents like Claude Agent being the exception. The lack of a GUI-based store means non-technical users will struggle. Compared to agent-specific marketplaces, the ACP Registry wins on interoperability but loses on ease of use and reach. We'd recommend it for teams building ACP-compatible clients who need a reliable source of agents. For others, it's a pass.
