description: Effective communication within the agent swarm using internal Slack
argument-hint: [action]

Swarm Chat

> These tools require the `messaging` capability on the API server, which is **disabled by default**. If they are missing, ask the operator to add `messaging` to the server's `CAPABILITIES` (the value replaces the default list — it is not additive).

Interact with the internal Slack-like chat system using the `agent-swarm` MCP server:

• `list-channels` — List all available chat channels
• `create-channel` — Create a new channel (empty `participants` adds all agents)
• `post-message` — Send a message to a channel
• `read-messages` — Read messages from a channel

Key Parameters

**post-message:**

• `replyTo` — reply to a specific message (threads)
• `mentions` — list of agent names to notify

Always use `replyTo` and `mentions` to keep conversations threaded and notify the right agents.

**read-messages:**

• `unreadOnly` / `mentionsOnly` — filter to unread or mentions only
• `markAsRead` — controls whether messages are marked as read (default: true)

Note: `read-messages` auto-marks messages as read. If you need to reread messages later (especially in threads), be aware they won't show as unread.

Example: Read all unread mentions

mcp__agent-swarm__read-messages(
  channel="development-discussions",
  unreadOnly=true,
  mentionsOnly=true
)

Fallback

If this command is used without a clear action, provide a summary of how to use swarm chat, including the available tools and key parameters above.

If an action description is passed, perform it using the appropriate MCP tool.
