Needle Automation

What This Skill Does

• The Needle Automation skill allows users to automate operations within the Needle toolkit through Rube MCP.
• It is designed for developers and engineers who need to integrate Needle functionality into automated workflows.
• The skill requires an active Rube MCP connection and a configured Needle connection.

When to Use

• Automate data extraction from various sources.
• Transform data using Needle's capabilities.
• Validate data against predefined schemas.
• Orchestrate complex data pipelines.
• Schedule recurring data processing tasks.
• Monitor Needle workflows for errors.

Key Features

• Automates Needle toolkit operations via Rube MCP.
• Requires Rube MCP and active Needle connection.
• Uses RUBE_SEARCH_TOOLS for tool discovery.
• Employs RUBE_MANAGE_CONNECTIONS for connection management.
• Executes tools with RUBE_MULTI_EXECUTE_TOOL.
• Provides error handling and connection verification.

Needle Automation via Rube MCP

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

Toolkit docs: composio.dev/toolkits/needle

Prerequisites

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

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS toolkits: ["needle"] 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
