Glassbox Framework

Overview

Glassbox Framework is an MCP server that performs runtime constitutional verification for AI answers. It enables claim reasoning, ECS analysis, red teaming, and audits to help validate and evaluate AI model outputs against defined constitutional principles.

The server runs locally via the npm package @glassbox-framework/mcp, communicating over stdio. Installation uses npx -y @glassbox-framework/mcp and requires ANTHROPIC_API_KEY for authentication. Version v1.0.3 is available under the Apache-2.0 license, with source code at TheBarmaEffect/glassbox on GitHub.

Glassbox Framework appears in the AI & Agents category and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Maintainers from TheBarmaEffect are welcome to claim this listing to verify ownership and keep information current.
