💡 idea: Add 'get_user_channels' tool to MCP server

[eshamir3]

Feature Request: List User's Channels

Problem:
Currently, AI agents cannot discover which channels a user is a member of. Users must manually specify channel names, which creates friction in workflows like "summarize my recent messages from all of my channels"

Proposed Solution:
Add a new MCP tool: get_my_channels (or list_user_channels)
I will make a PR for this

API Endpoint to use:

• GET /api/v4/users/me/channels (all channels)
• GET /api/v4/users/me/teams/{team_id}/channels (team-specific)

Parameters:

• team_id (optional): Filter channels by team
• limit (optional): Number of channels to return
• page (optional): For pagination

Returns:
List of channels with: channel_id, name, display_name, type, team_id, unread_count (if available)

Use Case:
Enable AI agents to:

• Automatically discover and summarize all user channels
• Provide channel activity overviews without manual specification
• Improve user experience for multi-channel workflows

Current Workaround:
Users must manually list channel names, limiting automation capabilities.
