# Send Slack Message

Send a message to a Slack channel. This demonstrates how Claude Code
handles messaging through MCP servers, compared to OpenClaw's 15+
native channel integrations.

## Prerequisites

You need a Slack MCP server configured in `.mcp.json`. Example:

```json
{
  "mcpServers": {
    "slack": {
      "command": "npx",
      "args": ["@anthropic-ai/mcp-slack@latest"],
      "env": {
        "SLACK_BOT_TOKEN": "xoxb-your-token-here"
      }
    }
  }
}
```

## Usage

Tell Claude Code: "Send a message to #general saying [your message]"

Claude Code will use the Slack MCP server's `send_message` tool.

## How this compares to OpenClaw

OpenClaw has native Slack integration (Bolt SDK, no config needed
beyond token). Claude Code uses MCP as the integration layer. The
result is the same: a message arrives in Slack. The setup differs:
OpenClaw is plug-and-play, Claude Code requires MCP configuration.

## Other messaging channels

- **Telegram:** Native via Claude Code Channels (v2.1.80+)
- **Discord:** Via MCP server
- **Email:** Via MCP server (e.g., Gmail MCP)
- **Teams:** Via MCP server or webhook
