Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed FlashData integration for looking up YouTube channel data, with expected API-key and network use.

Install only if you intend to use FlashData, have a protected FLASHDATA_API_KEY with the needed source enabled, and accept that channel handles and query settings are sent to FlashData and may spend paid Credits.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

## Connection and responses

For hosted MCP, connect `https://data.flashdata.dev/mcp` using Streamable HTTP and an `X-API-Key` header in your client's protected settings. Keep keys out of chat and committed files.

The CLI returns `{"ok":true,"tool":"youtube_channel","result":...}`; read the data inside `result`. MCP clients expose the same data in the tool response. Check errors before processing results. For a free quote, call `get_pricing` with `{"source":"youtube_channel","request_count":1}`; a quote does not run the data query.
