Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| send-ntfyA | Publish a message to the configured ntfy topic (set in mcp.json). Supports optional title, priority (1-5), tags, and attachUrl. After sending, use wait-and-read-inbox to wait for responses. |
| set-ntfy-topicB | Change the ntfy topic for this MCP server session (no restart needed). |
| wait-and-read-inboxA | Waits for new messages on the configured topic (set in mcp.json) and returns when a new message arrives. Does not return until at least one new message is received. Uses the existing subscription. Note: The MCP protocol has a ~60s client-side timeout that cannot be controlled from the server, but this tool will wait as long as possible within that limit. |
