Cruxible Core

Overview

Cruxible Core is a deterministic decision engine that lets you define rules in YAML, query a graph, and get proof of outcomes. As an MCP server, it exposes these capabilities as callable tools within AI assistants like Claude Desktop, so you can integrate rule-based reasoning directly into your workflows without switching between applications.

The server runs locally via the Python package cruxible-core, installed with uvx cruxible-core. It communicates over stdio and requires no credentials to operate. Version v0.1.2 is available now under the Apache-2.0 license, with source code at cruxible-ai/cruxible-core on GitHub.

Cruxible Core belongs in the AI & Agents category and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim this listing to verify your ownership and keep information current.
