Sync Slack and Discord

Mirror messages between a Slack channel and a Discord channel. Useful for communities that span both platforms.

Prerequisites

• Slack Bot Token with channels:history, chat:write scopes
• Discord Bot Token with message read/write permissions
• WCP running

1. Register Connections

# Slack
curl -X POST http://localhost:8000/api/connections \
  -H "Content-Type: application/json" \
  -d '{
    "name": "slack",
    "command": "npx",
    "args": ["-y", "@anthropic/mcp-server-slack"],
    "env": { "SLACK_BOT_TOKEN": "xoxb-..." }
  }'

# Discord
curl -X POST http://localhost:8000/api/connections \
  -H "Content-Type: application/json" \
  -d '{
    "name": "discord",
    "command": "npx",
    "args": ["-y", "@anthropic/mcp-server-discord"],
    "env": { "DISCORD_BOT_TOKEN": "MTI..." }
  }'

2. Scan & Sync

curl -X POST http://localhost:8000/api/capabilities/scan
curl -X POST http://localhost:8000/api/sync/run/await

3. Real-Time via WebSocket

For near-instant message bridging, listen for sync events and re-trigger:

const ws = new WebSocket('ws://localhost:8000/ws');
ws.onmessage = (e) => {
  const event = JSON.parse(e.data);
  if (event.type === 'sync_complete') {
    console.log(`Synced ${event.summary.synced} messages`);
  }
};

Tips

• Set conflict strategy to source_wins — messages should flow one-way per sync direction
• Run sync every minute for near-real-time bridging
• Use the Dashboard to monitor message flow visually
