Security Report

3.2
Use Caution3.2High Risk

Meta-Stamp Pockets is a FastAPI-based payment/licensing platform for AI-generated content with multi-provider LangChain integration. The codebase exhibits reasonable architecture and comprehensive testing, but has several security concerns that should be addressed: unauthenticated MCP server endpoints, broad LangChain dependency scope enabling arbitrary model access, environment variable exposure risks, and insufficient input validation on user-supplied parameters. The server's ability to call multiple external AI providers without per-operation rate limiting or usage tracking creates potential for abuse. Overall, the code quality is good but authentication and permission boundaries need hardening before production deployment. Supply chain analysis found 9 known vulnerabilities in dependencies (0 critical, 2 high severity).

Meta-Stamp Pockets

Attribution and settlement infrastructure for AI agent access.

AI agents consume creator content at machine speed. Meta-Stamp Pockets is the payment and licensing rail at the point of access: every request either settles payment to the creator or generates a timestamped denial record — a documented licensing opportunity, declined. License, or leave a paper trail.

What It Does

  • Serves licensed, provenance-tracked creator content to AI agents via the Model Context Protocol (MCP) and HTTP 402
  • Per-pull pricing set by the creator — $1.00 default, configurable per asset
  • 85% of every pull goes to the creator, automatically
  • Every access attempt lands in an immutable event ledger — paid pulls settle, refusals leave evidence

How Content Gets Protected

Two registration paths, each matched to how content arrives:

  • Direct upload — the file is perceptually fingerprinted (audio spectral analysis, image/video hashing, text signatures) and then discarded. The fingerprint travels; the file stays with the creator.
  • YouTube URL — ownership is verified through OAuth channel connection; the pocket carries metadata, transcript, and the access ledger. YouTube remains the canonical host.

Three protection layers are filed IP (12 U.S. provisional patent filings, sole inventor). Two run live today: multi-modal fingerprinting and the immutable access ledger. Embedded watermarking is the roadmap layer.
