magents MCP server

Claude Code, Codex, Copilot, Cursor, Gemini, Grok, and OpenCode already keep transcripts on disk. magents is the shared API over those sessions - an MCP server plus a small CLI - so one agent can pick up where another left off without you recapping, ping a specific live chat when you are not sitting in the middle, or start an independent persisted chat for a complete task.

It is not a second copy of history and not a fire-and-forget council. Existing chats stay the default unit of work; new chats are for independent work that benefits from its own session and working directory.

Why

You already run more than one coding agent. The pain is not "more models" - it is context trapped in another window.

What you can do

1. Handoff without a new thread You were in Claude on the disaster-recovery branch. Now you are in Grok. Ask Grok what they were doing; it reads the live session and continues. No paste buffer. No "new chat, here's the context."

2. Send when you are not the messenger Three agents running. Claude hits a wall Codex owns. Claude injects into that Codex thread and keeps going - especially useful when the sender already has the failing query, file, and constraint you would otherwise reconstruct.

3. Spawn independent work When a task can proceed alone, start a new headless persisted session with a complete prompt, an isolated working directory when files could collide, and a request to reply through magents. Spawned agents keep their host's native approval policy - spawning does not add an approval bypass.
