Install Glassbox Framework in Claude Code, Cursor or VS Code

Runs npx -y @glassbox-framework/mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Glassbox Framework repository's README, as published. We do not edit it. Read it on GitHub

Glass Box Framework

Runtime constitutional verification for AI answers. Every claim carries a reasoning chain. Every score breaks down. Every verdict is traceable.

⭐️ Star this repo if you want runtime AI verification to become the default. Every star moves Glassbox up the search ranking on GitHub, the MCP Registry, and Smithery — which means more developers find this before they ship an AI feature without a Trust Card.

pip install glassbox-framework         # Python
npm install -g @glassbox-framework/mcp # Node / MCP
brew install thebarmaeffect/glassbox/glassbox-mcp   # macOS

Zero-cost public GlassBox Lite

The repository also ships a separate deterministic Lite verifier and cross-platform gateway that require no paid model API:

  • Web app / installable PWA
  • Public remote MCP for ChatGPT, Claude, and compatible clients
  • GitHub App
  • Discord
  • Telegram
  • Notion: embed https://glassbox-platform-gateway.onrender.com/app
  • Browser, VS Code, and JetBrains packages: latest GitHub release

Lite performs bounded structural checks and does not browse or establish factual truth. The original six-tool model-assisted MCP documented below remains a separate surface.

See PLATFORMS.md for the exact live, downloadable, pilot, and external-review status of every integration.

What it is

The Glass Box Framework hands an (question, answer) pair to a runtime verification pipeline and returns a structured Trust Card containing:

  • Claims — every atomic assertion in the answer, paired with a reasoning chain explaining why it's asserted, what would support it, and what would falsify it.
  • Epistemic Confidence Score (ECS) — a transparent, weighted aggregate over five dimensions with a published formula and an always-visible per-dimension breakdown.
  • Glassbox Court — seven adversarial probes (fabrication, source manipulation, bias injection, context attack, overconfidence, underspecification, constitutional violation).
  • Constitution — your natural-language deployer intents compiled into structured runtime rules and evaluated against the answer.
  • Verdict — trust / caution / reject, with the exact reasoning that derived it.
  • Audit reference — a deterministic SHA-256 log_id; identical inputs reproduce the same identifier across runs and languages.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
