ACP Resources

​

The spec site, agentclientprotocol.com

• Get Started: the protocol’s own introduction, architecture overview, and separate guides for building an agent or a client.
• Protocol reference: the stable v1 schema and every method, in the spec’s own words. This SDK’s Errors and Concepts pages link back to specific protocol pages rather than repeating them.
• RFDs (Requests for Discussion): how the protocol itself changes, from draft through active, preview, and completed. The Streamable HTTP and WebSocket transport RFD is the authoritative source this SDK’s Transports page builds on.
• Updates and its Announcements: one post per protocol stabilization (elicitation, request cancellation, logout, session config options, and more), each explaining what changed and why.
• Publications: talks and write-ups about the protocol from outside the spec repository itself.
• Libraries: every known ACP implementation, by language, including the spec’s own Java page pointing back at this SDK.
• Registry: published, ACP-compatible agents an editor or IDE can connect to without writing one yourself.

​

Editors and IDEs

• Zed: “Bring Your Own Agent”: the announcement that introduced ACP, from the editor that originated it; see Zed’s own ACP docs for how to connect an agent today.
• JetBrains: Agent Client Protocol: ACP support across the JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, and the rest), connecting external agents into AI Assistant’s chat.
• VS Code ACP extension: a community extension bringing ACP agents into VS Code, not an official Microsoft integration.
