agent-intercom runs on your own machine — the client starts it, so there is no endpoint to ping. 917 installs a week from npm. Last commit 18 Oct 2026.
Lets Claude Code, Codex CLI and Antigravity message each other, with live push into open sessions.
What the code does
We read the source, 5 d ago · rules 995398eba69f
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
execFile(AGY, ['agentapi', 'send-message', sess.conversationId, render(m)], {
"(reply_to = the message id)." % json.dumps(os.environ["SELF"]))
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Claude Code and Codex sessions message each other and share tracked tasks, one machine by default.
One MCP server bridging the Codex, Cursor, OpenCode, Claude, and Antigravity CLI agents
Let one coding-agent CLI consult another: Codex, Claude Code, OpenCode, Copilot or Antigravity.
Search, resume and hand off coding-agent sessions: Claude Code, Codex, Gemini, Antigravity and more.
Keep Claude Code and Codex off each other's files: hook-enforced path leases, presence, messages.
