Do I always need to call RUBE_SEARCH_TOOLS first?

Yes. Tool schemas change, so fetch current slugs and schemas before execution.

What if the connection is not ACTIVE?

Follow the returned auth link to complete setup and ensure the status shows ACTIVE before running workflows.

What must be included in RUBE_MULTI_EXECUTE_TOOL calls?

Include memory (even if empty) and use exact field names/types from the discovered schema; reuse session IDs where appropriate.

Html To Image Automation via Rube MCP

Automate Html To Image operations through Composio's Html To Image toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/html_to_image

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Html To Image connection via RUBE_MANAGE_CONNECTIONS with toolkit html_to_image
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 html_to_image
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: "Html To Image 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 Html To Image task"}]
session: {id: "existing_session_id"}

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS
toolkits: ["html_to_image"]
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 Html To Image-specific use case
Connect	`RUBE_MANAGE_CONNECTIONS` with toolkit `html_to_image`
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

Automate Html To Image operations through Composio's Html To Image toolkit via Rube MCP. The workflow emphasizes discovering current tool schemas, validating the HTML-to-image connection, and executing tools in a schema-compliant, session-aware manner to ensure reliable image generation.

How This Skill Works

Start by discovering available tools with RUBE_SEARCH_TOOLS to get current slugs and input schemas. Then verify the html_to_image connection using RUBE_MANAGE_CONNECTIONS and ensure the status is ACTIVE. Finally execute the chosen tool via RUBE_MULTI_EXECUTE_TOOL using the discovered slug, exact schema fields, and include a memory payload, reusing an existing session ID when appropriate.

When to Use It

You need to render HTML to images in an automated pipeline and must fetch the latest tool schemas first.
Setting up or validating a Rube MCP connection for the html_to_image toolkit.
Running a batch of Html To Image tasks with RUBE_MULTI_EXECUTE_TOOL using discovered tool slugs.
Reusing a session ID across a workflow to improve efficiency and consistency.
Handling schema changes or pagination when discovering available tools.

Quick Start

Step 1: Connect Rube MCP and verify tool schemas with RUBE_SEARCH_TOOLS.
Step 2: Manage the html_to_image connection with RUBE_MANAGE_CONNECTIONS and confirm ACTIVE.
Step 3: Execute a tool via RUBE_MULTI_EXECUTE_TOOL using the discovered slug and memory, with a valid session_id.

Best Practices

Always call RUBE_SEARCH_TOOLS before selecting a tool_slug to get current schemas.
Verify RUBE_MANAGE_CONNECTIONS shows ACTIVE before executing any tools.
Use exact field names and types from the search results; avoid hardcoding slugs.
Include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty.
Reuse session IDs within a workflow and generate new ones for new runs; watch for pagination tokens.

Example Use Cases

Daily dashboard HTML rendered to images for executive reports.
Batch rendering of product pages to generate a catalog of image assets.
Rendering HTML marketing email templates to images for previews.
Generating images from responsive HTML with multiple viewport settings.
Schema-driven tool selection: fetch schemas with RUBE_SEARCH_TOOLS before execution.
