Glassbox-framework MCP Server

Glassbox-framework is an MCP integration. Runtime constitutional verification for AI answers — claim reasoning, ECS, red team, audits.

Packages and local setup

The published npm package is @glassbox-framework/mcp, version 1.0.3. Its declared MCP transport is stdio.

The package declares ANTHROPIC_API_KEY (required): 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: Override the Claude model used by the verification engines. Defaults to claude-sonnet-4-6.; GLASSBOX_MAX_TOKENS: Per-engine-call max-tokens cap. Defaults to 2048; raise for verifying long-form content.; GLASSBOX_ECS_MODE: ECS aggregation mode: arithmetic (weighted mean, default) or geometric (stricter — any zero dimension collapses the total)..
