Summary

This skill itself is an open-source prompt/documentation artifact and does not directly require local secrets or embed code execution. However, it is designed to connect to a remote Rube MCP service and operate external Composio/Ncscale tooling, so it warrants caution rather than a high-risk rating.

CredentialsCaution

The material says there is 'no API key,' but it requires creating an ACTIVE `ncscale` connection via `RUBE_MANAGE_CONNECTIONS` and completing an auth link, which implies third-party account authorization or token handling. The docs do not state where credentials are stored, what scopes are granted, or how revocation works.

Network egressCaution

It explicitly requires adding the remote MCP endpoint `https://rube.app/mcp` and using the Composio/Ncscale toolchain for discovery, connection, and execution. This means task arguments, session IDs, and possibly business data are sent to declared external services, but the material does not detail data flows or retention practices.

Code executionLow risk

Based on the objective checks, this is a prompt-only skill. The material contains no local install script, shell command, or instruction to directly execute code on the host; its role is to guide use of remote MCP tools rather than grant local code execution.

Data accessCaution

The skill itself does not declare reading local files or databases, but through `RUBE_MULTI_EXECUTE_TOOL`, `RUBE_REMOTE_WORKBENCH`, and session/memory parameters it can perform operations on external Ncscale resources. The effective data access scope depends on the connected account's permissions, and the docs do not define least-privilege boundaries.

Supply chainLow risk

The source is a GitHub open-source repository with very strong community adoption (about 64.9k stars), which materially lowers supply-chain risk. The current material is also only a skill description text. Still, the missing license declaration and unknown maintenance status mean the downstream Rube/Composio services should be reviewed separately.

Recommendations

Before connecting, verify how `rube.app`, Composio, and Ncscale handle data processing, logging, and credential storage.
Use a least-privilege Ncscale account for the connection and confirm the granted scopes and revocation process.
Run `RUBE_MULTI_EXECUTE_TOOL` or bulk operations only when necessary, and avoid sending unnecessary sensitive business data to remote tools.
Treat this skill as workflow guidance; the main security exposure lies in the connected remote MCP/third-party services, not in the prompt text itself.

Ncscale Automation via Rube MCP

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

Toolkit docs: composio.dev/toolkits/ncscale

Prerequisites

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

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS
toolkits: ["ncscale"]
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 Ncscale-specific use case
Connect	`RUBE_MANAGE_CONNECTIONS` with toolkit `ncscale`
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`
