Automate Mailersend operations through Composio's Mailersend toolkit via Rube MCP.
Toolkit docs: composio.dev/toolkits/mailersend
Prerequisites
- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
- Active Mailersend connection via
RUBE_MANAGE_CONNECTIONSwith toolkitmailersend - Always call
RUBE_SEARCH_TOOLSfirst 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_TOOLSresponds - Call
RUBE_MANAGE_CONNECTIONSwith toolkitmailersend - 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: "Mailersend 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 Mailersend task"}]
session: {id: "existing_session_id"}
Step 2: Check Connection
RUBE_MANAGE_CONNECTIONS
toolkits: ["mailersend"]
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_CONNECTIONSshows ACTIVE status before executing tools - Schema compliance: Use exact field names and types from the search results
- Memory parameter: Always include
memoryinRUBE_MULTI_EXECUTE_TOOLcalls, 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

This skill lets you orchestrate Mailersend operations through Composio's toolkit via Rube MCP. It emphasizes fetching current tool schemas first with RUBE_SEARCH_TOOLS and establishing an active Mailersend connection before executing workflows.
How This Skill Works
Discover available Mailersend tools with RUBE_SEARCH_TOOLS, verify the Mailersend connection via RUBE_MANAGE_CONNECTIONS, then execute the chosen tool using RUBE_MULTI_EXECUTE_TOOL. Always include a memory object and use the schema-provided field names; avoid hardcoding slugs or arguments.
When to Use It
- When you need to automate a Mailersend workflow end-to-end by discovering the correct tool and executing it
- When tool schemas change and you must fetch current slugs and arguments before running
- When performing batch or scheduled Mailersend tasks within a larger Composio workflow
- When you must confirm the Mailersend connection is ACTIVE prior to execution
- When integrating Mailersend tasks into multi-step sessions and reusing session IDs
Quick Start
- Step 1: Add the MCP endpoint and verify RUBE_SEARCH_TOOLS returns available tools
- Step 2: Establish a Mailersend connection with RUBE_MANAGE_CONNECTIONS (toolkit 'mailersend')
- Step 3: Execute a discovered tool using RUBE_MULTI_EXECUTE_TOOL with memory parameter
Best Practices
- Always search for current tool schemas with RUBE_SEARCH_TOOLS before any run
- Check that RUBE_MANAGE_CONNECTIONS shows ACTIVE status before executing tools
- Use exact field names and types from the search results; do not hardcode slugs or args
- Always include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty ({})
- Reuse session IDs within a workflow and generate a new one for new workflows
Example Use Cases
- Discover a Mailersend tool for sending a batch email and execute it with the required arguments
- Schedule a campaign by locating the appropriate tool and supplying the scheduled time and recipients
- Fetch delivery statistics for a campaign and log results in memory for later reporting
- Update recipient lists or tags by running a corresponding Mailersend tool with updated fields
- Retry a failed send by initiating a new session and re-running the tool with updated parameters
