About glassbox-framework
glassbox-framework is an MCP server published by the GitHub account TheBarmaEffect. Runtime constitutional verification for AI answers — claim reasoning, ECS, red team, audits.
It runs on your own machine: your AI client starts it from the npm package @glassbox-framework/mcp at version 1.0.3.
It asks for one secret: ANTHROPIC_API_KEY. Give it a key with the least access that still works.
Version 1.0.3 was published on 25 May 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
ANTHROPIC_API_KEY | Yes | Yes | Your Anthropic API key (sk-ant-...). Required for the claim extractor, red team, constitution engines, and ECS coherence checks. One v1 tool (generate_trust_card) works without an API key — it's pure assembly + deterministic audit hashing. |
GLASSBOX_MODEL | No | No | Override the Claude model used by the verification engines. Defaults to claude-sonnet-4-6. |
GLASSBOX_MAX_TOKENS | No | No | Per-engine-call max-tokens cap. Defaults to 2048; raise for verifying long-form content. |
GLASSBOX_ECS_MODE | No | No | ECS aggregation mode: arithmetic (weighted mean, default) or geometric (stricter — any zero dimension collapses the total). |
