Full Analysis
- [REMOTE_CODE_EXECUTION]: The configuration instructions in
references/configs.mdguide users to run the MCP server usingnpx -y zephex. This command downloads and executes thezephexpackage from the npm registry at runtime. This is the intended method for running the vendor's tool. - [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection via the
zephex:inspect_urltool. - Ingestion points: The tool
zephex:inspect_urlfetches content from any public URL provided by the user or found in the codebase (documented inreferences/tools.md). - Boundary markers: No specific instructions are provided to delimit this external content or warn the agent to ignore instructions embedded within the fetched data.
- Capability inventory: The agent has access to sensitive capabilities including reading local source code (
zephex:read_code), performing repository-wide searches (zephex:find_code), and it is instructed to performnpm installoperations after checking packages. - Sanitization: While the tool is described as 'cleaning' content, no specific security sanitization or validation of the fetched content is described to prevent prompt injection.
