mcp-installer

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 1.00). This skill explicitly searches GitHub and fetches repository files/READMEs using mcp__github__search_repositories and mcp__github__get_file_contents to extract npx configuration, so it will read and interpret arbitrary public, user-generated content from the open web.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill uses the mcp__github__get_file_contents tool at runtime to fetch raw GitHub file contents (e.g. https://raw.githubusercontent.com/...) and extracts npx install commands from those READMEs which are then inserted into the agent's configuration (and could cause remote code execution via npx), so the fetched GitHub/raw content directly controls executable commands.
