Security audit

context7-mcp

Security checks for vulnerabilities and agentic risk

Overview

This documentation helper is purpose-aligned and contains no executable code, persistence, credential handling, or hidden high-impact behavior.

Install this if you want the agent to prefer current Context7 documentation for library and framework questions. Be aware it may trigger on many programming prompts that mention a framework, which can add external documentation lookups even when general coding help might have been enough.

A.I.G

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

Finding
The manifest and body say to use the skill whenever the user asks about libraries, frameworks, API references, code examples, setup questions, or merely mentions frameworks. These triggers are broad, lack clear exclusion conditions, and could cause unintended invocation on many ordinary programming requests that do not actually require documentation lookup.
