### Description (declared)

# MCP Talk

Inter-agent messaging via Model Context Protocol (MCP).

A lightweight messaging system that enables AI agents (Claude, Codex, Gemini, etc.) to communicate with each other in real-time through a shared message queue.

## Features

- **Simple tools**: `send`, `check`, `ack`, `broadcast`, `list`, `clean`, `reply`
- **File-based persistence**: Messages stored as JSON files for easy debugging
- **Namespace isolation**: Separate message queues per project
- **Cross-agent**: Works with any MCP-compatible AI assistant
- **Zero dependencies**: Just Python 3.10+ and the MCP SDK

## Installation

```bash
# From PyPI (recommended)
pipx install mcp-talk

# Or with pip
pip install mcp-talk

# From source
git clone https://github.com/devinvenable/mcp-talk.git
cd mcp-talk
pipx install .
```

## Configuration

Add to your MCP client configuration:

### Claude Desktop / Claude Code

```json
{
  "mcpServers": {
    "mcp-talk": {
      "command": "mcp-talk"
    }
  }
}
```

### Using uvx (no install required)

```json
{
  "mcpServers": {
    "mcp-talk": {
      "command": "uvx",
      "args": ["mcp-talk"]
    }
  }
}
```

### Codex CLI (~/.codex/config.toml)

```toml
[mcp_servers.mcp-talk]
command = "mcp-talk"
```

### Gemini CLI (~/.gemini/settings.json)

```json
{
  "mcpServers": {
    "mcp-talk": {
      "command": "mcp-talk"
    }
  }
}
```

## Tools

### `send` - Send a direct message
```
send(to="codex", message="Please review PR #123", from_agent="claude")
```

### `check` / `chk` - Check messages
```
check(agent="claude")
chk(agent="claude", include_body=true, auto_ack=true)
```
Returns up to 5 messages by default. Use `include_body=true` for full message text, `auto_ack=true` to delete after reading.

### `broadcast` - Send to all agents
```
broadcast(message="Standup in 5 minutes", from_agent="pm")
```

### `ack` - Acknowledge/delete a message
```
ack(id="20251126_143022_abc12345")
```

### `reply` - Reply to a message
```
reply(id="20251126_143022_abc12345", me…
