Tools (4)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • list_patterns

    List all indirect prompt injection patterns that the scanner can detect, grouped by category

  • scan_directory

    Recursively scan a directory — e.g. a RAG knowledge base or a corpus of scraped pages — for indirect prompt injection payloads. Automatically skips node_modules, .git, dist, and binary files.

  • scan_file

    Scan a single file (a knowledge-base document, an HTML page, extracted text) for indirect prompt injection payloads

  • scan_text

    Scan a text string — a RAG chunk, a scraped web page, a document, a tool result — for indirect prompt injection payloads (instruction-override phrases, spoofed chat-template roles, hidden/invisible text, content addressing 'the AI' directly, data-exfiltration attempts) before it reaches a model's context.
