# claude-peers
Let your Claude Code instances find each other and talk. When you're running 5 sessions across different projects, any Claude can discover the others and send messages that arrive instantly.
```
Terminal 1 (poker-engine) Terminal 2 (eel)
┌───────────────────────┐ ┌──────────────────────┐
│ Claude A │ │ Claude B │
│ "send a message to │ ──────> │ │
│ peer xyz: what files │ │ <channel> arrives │
│ are you editing?" │ <────── │ instantly, Claude B │
│ │ │ responds │
└───────────────────────┘ └──────────────────────┘
```
## Quick start
### 1. Install
```bash
git clone https://github.com/louislva/claude-peers-mcp.git ~/claude-peers-mcp # or wherever you like
cd ~/claude-peers-mcp
bun install
```
### 2. Register the MCP server
This makes claude-peers available in every Claude Code session, from any directory:
```bash
claude mcp add --scope user --transport stdio claude-peers -- bun ~/claude-peers-mcp/server.ts
```
Replace `~/claude-peers-mcp` with wherever you cloned it.
### 3. Run Claude Code with the channel
```bash
claude --dangerously-skip-permissions --dangerously-load-development-channels server:claude-peers
```
That's it. The broker daemon starts automatically the first time.
> **Tip:** Add it to an alias so you don't have to type it every time:
>
> ```bash
> alias claudepeers='claude --dangerously-load-development-channels server:claude-peers'
> ```
### 4. Open a second session and try it
In another terminal, start Claude Code the same way. Then ask either one:
> List all peers on this machine
It'll show every running instance with their working directory, git repo, and a summary of what they're doing. Then:
> Send a message to peer [id]: "what are you working on?"
The other Claude receives it immediately and responds.
## What Claude can do
| Tool | What it does |
| ---------------- | ------------------------------------------------------------------------------ |
| `list_peers` | Find other Claude Code instances — scoped to `machine`, `directory`, or `repo` |
| `send_message` | Send a message to another instance by ID (arrives instantly via channel push) |
| `set_summary` | Describe what you're working on (visible to other peers) |
| `check_messages` | Manually check for messages (fallback if not using channel mode) |
## How it works
A **broker daemon** runs on `localhost:7899` with a SQLite database. Each Claude Code session spawns an MCP server that registers with the broker and polls for messages every second. Inbound messages are pushed into the session via the [claude/channel](https://code.claude.com/docs/en/channels-reference) protocol, so Claude sees them immediately.
```
┌───────────────────────────┐
│ broker daemon │
│ localhost:7899 + SQLite │
└──────┬───────────────┬────┘
│ │
MCP server A MCP server B
(stdio) (stdio)
│ │
Claude A Claude B
```
The broker auto-launches when the first session starts. It cleans up dead peers automatically. Everything is localhost-only.
## Auto-summary
If you set `OPENAI_API_KEY` in your environment, each instance generates a brief summary on startup using `gpt-5.4-nano` (costs fractions of a cent). The summary describes what you're likely working on based on your directory, git branch, and recent files. Other instances see this when they call `list_peers`.
Without the API key, Claude sets its own summary via the `set_summary` tool.
## CLI
You can also inspect and interact from the command line:
