Proliferate ACP Adapters

Positioning#

Proliferate ACP Adapters is a set of adapter tools built on the Agent Client Protocol (ACP). Its core objective is to solve the integration coupling between AI coding agents and code editors. Through a standardized protocol similar to LSP, it seamlessly connects AI capabilities like Claude Agent SDK and Codex into ACP-compatible clients (such as the Zed editor).

Note: The original entry repository proliferate-ai/proliferate returns 404. Whether this repo ever existed and when it was removed cannot be confirmed. The information below is compiled from the two remaining active repos in the organization.

Core Capabilities#

The project consists of two main components: claude-agent-acp written in TypeScript and codex-acp written in Rust (forked from Zed Industries' official repo). Both provide extensive feature support, including Context @-mentions, image input, tool calling with permission handling, following, edit reviewing, TODO list management, and interactive terminal integration. Additionally, they support custom Slash commands, custom Prompts, and client-side MCP server extensions.

claude-agent-acp specific: Custom Slash commands, interactive/background terminals.

codex-acp specific: Predefined Slash commands (/review, /review-branch, /review-commit, /init, /compact, /logout), custom Prompts.

Architecture Design#

It adopts a fully decoupled architecture where the editor and the Agent communicate via JSON-RPC over stdio (local subprocess) or HTTP/WebSocket (remote deployment). The core flow is: ACP-compatible editor ↔ (JSON-RPC over stdio/HTTP) ↔ ACP Adapter ↔ Agent SDK/CLI. This design eliminates the need for editors to develop separate integration modules for each Agent; they only need to implement the ACP protocol to connect to various AI coding assistants.

Deployment & Usage#

codex-acp:

• npm: npx @proliferateai/codex-acp
• Binary: Download pre-compiled binaries from GitHub Releases
• Run: OPENAI_API_KEY=sk-... codex-acp
• Zed editor has built-in support — select "New Codex Thread" in the Agent Panel
• Auth: Supports OPENAI_API_KEY, CODEX_API_KEY env vars or ChatGPT paid subscription auth (subscription auth does not support remote projects)

claude-agent-acp:

• Distributed via npm; exact package name not explicitly stated in README
• Latest known version: v0.24.2-proliferate.5
• Requires Claude Agent SDK authentication config (details TBD)

Unconfirmed Information#

• Whether the GitHub org proliferate-ai (ACP adapter development) and the website proliferate.ai (online tutoring platform) are the same entity cannot be confirmed
• The org page shows no public members; team background and project motivation are unknown
• claude-agent-acp's exact npm package name and install commands are missing
