Frequently asked questions
How can I check if a specific user is currently online in a channel?
You can use the presence_here_now tool to see a list of all active UUIDs in a specific channel, or presence_where_now to find all channels a specific UUID is currently subscribed to.
Can the AI retrieve past messages from a channel?
Yes, the get_message_history tool allows the agent to fetch historical messages from one or more channels, including metadata and specific time ranges.
Is it possible to manage user profiles and metadata through this server?
Absolutely. You can use set_user to create or update profiles and get_user to retrieve them. You can also manage channel metadata using set_channel and get_channel.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
