# Postmark Automation via Rube MCP Automate Postmark transactional email operations through Composio's Postmark toolkit via Rube MCP. ## Prerequisites - Rube MCP must be connected (RUBE_SEARCH_TOOLS available) - Active Postmark connection via `RUBE_MANAGE_CONNECTIONS` with toolkit `postmark` - Always call `RUBE_SEARCH_TOOLS` first to get current tool schemas ## Setup **Get Rube MCP**: Add `https://rube.app/mcp` as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works. 1. Verify Rube MCP is available by confirming `RUBE_SEARCH_TOOLS` responds 2. Call `RUBE_MANAGE_CONNECTIONS` with toolkit `postmark` 3. If connection is not ACTIVE, follow the returned auth link to complete Postmark authentication 4. Confirm connection status shows ACTIVE before running any workflows ## Core Workflows ### 1.
