Common questions

Is agent-intercom safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AGENT_NAME

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.5) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Let Claude Code, Codex CLI and Antigravity (Gemini) message each other,

and land each message straight in the other agent's open session.

Get started

npx agent-intercom install

Using Claude Code only? Install it as a plugin instead:

/plugin install agent-intercom --marketplace iambashar/agent-intercom

On Claude Code older than 2.1.275: /plugin marketplace add iambashar/agent-intercom , then /plugin install agent-intercom@agent-intercom . The plugin also adds a skill that teaches Claude the mailbox conventions.

The npx command registers the MCP server with every CLI it finds. Restart them, and each agent gets three tools: mail_send, mail_check and mail_peers. Then ask in plain words:

You → Claude: Ask codex to review the diff in src/parser.ts and wait for its answer.

Turn on live push so nobody has to poll. Install it globally, because the daemon needs a stable path:

npm i -g agent-intercom

agent-intercom install --push

What install changes, per CLI

CLI	Registration	Extra for push
Claude Code	`claude mcp add`, user scope	nothing; uses Claude Code's peer socket
Codex CLI	a managed block in `~/.codex/config.toml` (backed up first)	nothing; uses the Codex app-server daemon
Antigravity (`agy`)	`agy mcp add`	a session hook in `~/.gemini/config/hooks.json`

Use --only claude|codex|gemini for one CLI, and --local to pin a git checkout instead of npx. agent-intercom uninstall removes all of it, including the push daemon.

[!NOTE]

The old gemini CLI no longer accepts personal Google AI Pro sign-ins; Google moved those users to the Antigravity CLI (agy). Its agent is named gemini here by default.

See it work

Neither agent polls. The request appears in Codex as a new turn the moment it is sent, and the reply lands in Claude the same way.

What you get

Supported agents

Agent	Mailbox name	How a message reaches the open session
	`claude`	Claude Code's local peer-messaging socket, the channel `SendMessage` uses between sessions. Arrives labelled as from another session.
	`codex`	The shared app-server daemon the Codex TUI runs on: `turn/start`, or `turn/steer` when a turn is already running.
	`gemini`	`agy agentapi send-message` into the conversation. Each session registers itself once through a hook.
Any other MCP client	anything	No push. It reads with `mail_check`, or blocks with `mail_check(wait_seconds=300)`.

Tool	What it does
`mail_send(to, body, reply_to?)`	Drop a message in another agent's inbox
`mail_check(wait_seconds?)`	Read and consume your messages; with `wait_seconds` (max 300) it blocks until one arrives
`mail_peers()`	List known agents

How push works

sequenceDiagram

autonumber participant C as Claude Code participant M as ~/.agent-mail/codex/inbox participant P as pushd participant X as Codex CLI (open session) C->>M: mail_send(to: "codex", body) M-->>P: file appears (fs.watch, no polling) P->>M: claim: rename to .json.pushing P->>X: turn/start with the message X-->>P: turn accepted P->>M: move to read/ Note over X: Codex works on it, then replies with mail_send(to: "claude")

Delivered once. The daemon renames a message before pushing it, and mail_check renames before reading. Whoever wins the rename delivers it.
Fails safe. A failed push puts the file back in the inbox and retries after 30 s. If no session is open, the message waits for mail_check.
Addressing. Pick a session with claude. , codex. or gemini. . Otherwise the most recently active session gets it, or the one named in ~/.agent-mail/routes.json:

  { "claude": "api-server", "codex": "019f018a" }

[!WARNING]

Push relies on undocumented internals of all three CLIs, and an update can change them without notice. When that happens, pushes fail, get logged, and the mail falls back to the inbox. Protocol details: docs/live-push.md.

Without the push daemon

Claude Code: docs/claude-monitor.md. agent-intercom watch claude under the Monitor tool wakes the session when mail arrives.
Codex: docs/codex-listen.md. A listener prompt that loops on mail_check(wait_seconds=300).

Across machines

Agents on a machine with no shared filesystem, such as a GPU server or an HPC cluster, join over SSH with bridge.sh. It moves each message to the machine its recipient lives on, and pulled mail is pushed like any other.

BRIDGE_HOST=gpu-box REMOTE_AGENTS="claude-gpu" ./bridge.sh

More: docs/remote-bridge.md.

More than one session per CLI

Names are just AGENT_NAME. Give each session its own, for example claude-api and claude-web:

npx agent-intercom install --only claude --claude-name claude-api

CLI

agent-intercom install [--only claude|codex|gemini] [--claude-name N] [--codex-name N] [--gemini-name N] [--local] [--push]

agent-intercom uninstall MCP entries, agy hook and push daemon agent-intercom push install push daemon as a login service (launchd / systemd --user) agent-intercom push uninstall agent-intercom push run push daemon in the foreground agent-intercom status unread/read counts per agent agent-intercom watch one line per new message, without consuming it agent-intercom serve the MCP server on stdio

Security

This is a local mailbox with no authentication. Any process running as you can write to ~/.agent-mail/*/inbox, and an agent treats a message as input to act on. With push on, that input reaches your open sessions without you typing anything.

Treat inbox contents as untrusted text. Don't
