What is smtp2go-automation?

It is a Composio-based workflow that automates Smtp2go tasks by discovering current tool schemas and securely executing them via Rube MCP.

Do I need to call RUBE_SEARCH_TOOLS first?

Yes. Always search tools first to obtain up-to-date tool slugs and input schemas before any execution.

What if the connection is not ACTIVE?

Follow the returned authentication flow from RUBE_MANAGE_CONNECTIONS to complete setup, then verify ACTIVE status before running workflows.

Smtp2go Automation via Rube MCP

Automate Smtp2go operations through Composio's Smtp2go toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/smtp2go

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Smtp2go connection via RUBE_MANAGE_CONNECTIONS with toolkit smtp2go
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.

Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
Call RUBE_MANAGE_CONNECTIONS with toolkit smtp2go
If connection is not ACTIVE, follow the returned auth link to complete setup
Confirm connection status shows ACTIVE before running any workflows

Tool Discovery

Always discover available tools before executing workflows:

RUBE_SEARCH_TOOLS
queries: [{use_case: "Smtp2go operations", known_fields: ""}]
session: {generate_id: true}

This returns available tool slugs, input schemas, recommended execution plans, and known pitfalls.

Core Workflow Pattern

Step 1: Discover Available Tools

RUBE_SEARCH_TOOLS
queries: [{use_case: "your specific Smtp2go task"}]
session: {id: "existing_session_id"}

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS
toolkits: ["smtp2go"]
session_id: "your_session_id"

Step 3: Execute Tools

RUBE_MULTI_EXECUTE_TOOL
tools: [{
  tool_slug: "TOOL_SLUG_FROM_SEARCH",
  arguments: {/* schema-compliant args from search results */}
}]
memory: {}
session_id: "your_session_id"

Known Pitfalls

Always search first: Tool schemas change. Never hardcode tool slugs or arguments without calling RUBE_SEARCH_TOOLS
Check connection: Verify RUBE_MANAGE_CONNECTIONS shows ACTIVE status before executing tools
Schema compliance: Use exact field names and types from the search results
Memory parameter: Always include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty ({})
Session reuse: Reuse session IDs within a workflow. Generate new ones for new workflows
Pagination: Check responses for pagination tokens and continue fetching until complete

Quick Reference

Operation	Approach
Find tools	`RUBE_SEARCH_TOOLS` with Smtp2go-specific use case
Connect	`RUBE_MANAGE_CONNECTIONS` with toolkit `smtp2go`
Execute	`RUBE_MULTI_EXECUTE_TOOL` with discovered tool slugs
Bulk ops	`RUBE_REMOTE_WORKBENCH` with `run_composio_tool()`
Full schema	`RUBE_GET_TOOL_SCHEMAS` for tools with `schemaRef`

Overview

This skill automates Smtp2go operations through Composio's Rube MCP toolkit, emphasizing live discovery of tool schemas before execution. It ensures an active Smtp2go connection and uses session-based tool execution to keep workflows reliable and up-to-date.

How This Skill Works

It starts by calling RUBE_SEARCH_TOOLS to fetch current Smtp2go tool slugs and input schemas, then verifies an active connection with RUBE_MANAGE_CONNECTIONS using the smtp2go toolkit. Finally, it runs the chosen tool via RUBE_MULTI_EXECUTE_TOOL with memory and the schema-compliant arguments from the discovered tool.

When to Use It

Automating a specific Smtp2go task (e.g., sending a transactional email) after discovering the appropriate tool slug and schema.
Setting up or validating a fresh smtp2go connection before running any workflows.
Chaining multiple Smtp2go tasks in a single workflow using a session to maintain context.
Updating or validating tool schemas by fetching the latest results with RUBE_SEARCH_TOOLS and, if needed, RUBE_GET_TOOL_SCHEMAS.
Performing bulk or repeated smtp2go tasks with memory-preserving tool executions and proper pagination handling.

Quick Start

Step 1: Verify Rube MCP is available by running RUBE_SEARCH_TOOLS.
Step 2: Configure and activate the smtp2go connection with RUBE_MANAGE_CONNECTIONS (toolkit: smtp2go).
Step 3: Discover a tool slug, then execute it using RUBE_MULTI_EXECUTE_TOOL with the discovered schema-compliant arguments and memory.

Best Practices

Always call RUBE_SEARCH_TOOLS first to obtain current tool slugs and input schemas.
Ensure RUBE_MANAGE_CONNECTIONS shows ACTIVE before executing any tool.
Use exact field names and types from the discovered tool schemas; do not hardcode slugs or arguments.
Include memory: {} in every RUBE_MULTI_EXECUTE_TOOL call, even if empty.
Reuse session IDs within a workflow and fetch new ones only for separate workflows.

Example Use Cases

Discover tools with RUBE_SEARCH_TOOLS for Smtp2go operations, then execute a tool slug like TOOL_SLUG_FROM_SEARCH with args {to, subject, body}.
Connect to smtp2go via RUBE_MANAGE_CONNECTIONS, verify ACTIVE, then run a batch email tool such as SendBulkCampaign.
Use RUBE_GET_TOOL_SCHEMAS to inspect a tool's schemaRef before building arguments for RUBE_MULTI_EXECUTE_TOOL.
Chain multiple smtp2go tools in a single session by reusing the same session_id while executing TOOL_SLUG_FROM_SEARCH and subsequent tools.
Run bulk operations through RUBE_REMOTE_WORKBENCH by calling run_composio_tool() on multiple smtp2go tasks.
