API Tool Calls
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed guide for using a remote API Tool Calls MCP service, with no bundled executable code or hidden local behavior found.
Before installing, understand that this skill depends on a third-party remote MCP service and optional external CLI installer. Use it only for data you are comfortable sending to that service, keep API keys in client credentials or environment settings as instructed, and review tool schemas before calling tools that process personal, resume, location, or business information.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- 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
