Remote Agent Server: a self-hosted Web/API runtime for ACP coding agents

[ma-pony]

I've been building Remote Agent Server, a self-hosted ACP client/runtime that runs coding agents such as Codex and Claude Code behind a Web UI and asynchronous HTTP API.

It uses acpx to communicate with Provider agents over ACP. The server adds the operational pieces needed for remote, long-running use:

• reusable multi-repository project environments and snapshot-based Session workspaces on APFS/Btrfs;
• persistent multi-turn Sessions, Run events, cancellation and Token accounting;
• per-Agent Skills, Provider plugins and Hooks, HTTP/stdio MCP, and per-tool filtering;
• integration endpoints with polling, SSE and signed Webhooks;
• configurable concurrency while keeping Runs in the same Session serialized.

Repository: https://github.com/ma-pony/remote-agent-server

First public release: https://github.com/ma-pony/remote-agent-server/releases/tag/v0.1.0

I would value feedback from other ACP client implementers on session restart/resume semantics and dynamic MCP injection. Those are the two areas where Provider behavior has differed most in practice.
