detect_deepfake_image
Analyze image metadata to detect AI-generated signatures. Checks EXIF, PNG chunks, and compression patterns for known AI tool markers.
Instructions
Check image metadata for AI generation signatures.
Performs lightweight metadata-based analysis (EXIF, PNG chunks, compression patterns) without requiring ML inference. Checks for known AI tool signatures, suspicious metadata patterns, and generation parameters.
Args: image_base64: Base64-encoded image data. image_path: Local file path to image (alternative to base64).
Returns: Detection results with metadata findings and risk assessment.
Behavior: This tool generates structured output without modifying external systems. Output is deterministic for identical inputs. No side effects. Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage.
When to use: Use this tool when you need structured analysis or classification of inputs against established frameworks or standards.
When NOT to use: Not suitable for real-time production decision-making without human review of results. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage. Pro/Enterprise tiers require a valid MEOK API key passed via the MEOK_API_KEY environment variable. - Rate Limits: Free tier: 10 calls/day. Pro tier: unlimited. Rate limit headers are included in responses (X-RateLimit-Remaining, X-RateLimit-Reset). - Error Handling: Returns structured error objects with 'error' key on failure. Never raises unhandled exceptions. Invalid inputs return descriptive validation errors. - Idempotency: Fully idempotent — calling with the same inputs always produces the same output. Safe to retry on timeout or transient failure. - Data Privacy: No input data is stored, logged, or transmitted to external services. All processing happens locally within the MCP server process.
