Audited by Gen Agent Trust Hub on Oct 25, 2026
Risk Level: SAFE
Full Analysis
- [SAFE]: The skill acts as an instructional framework for developing MCP servers. It does not contain malicious code, hidden instructions, or exfiltration patterns.
- [REMOTE_CODE_EXECUTION]: The provided code snippets demonstrate how to make legitimate API calls to well-known services (e.g., GitHub API) using standard libraries like
httpxand the Model Context Protocol SDK. These are presented as educational templates. - [CREDENTIALS_SAFE]: The skill explicitly instructs users to manage sensitive information like API keys and tokens through environment variables (e.g.,
os.environ['GITHUB_TOKEN']) and configuration files, rather than hardcoding them into the server logic. - [INDIRECT_PROMPT_INJECTION]: While the skill describes building tools that ingest external data, it proactively mitigates injection risks by mandating typed parameters (Zod/Pydantic), input validation at the boundary, and sanitization of agent-supplied parameters.
- [COMMAND_EXECUTION]: The skill includes example configurations for running MCP servers via
nodeandpython. These are standard execution patterns for the protocol and are used to demonstrate local deployment.
