registry vs chiasmus

registry: MCP Armory Registry provides production-ready MCP servers for popular APIs, generated from OpenAPI specs. Each server is a standalone Python package tested against live APIs. Hosted on MCP Armory or run independently.; chiasmus: Chiasmus is an MCP server that integrates formal verification (Z3, Prolog) and code analysis (tree-sitter) to solve complex logical and structural problems. It translates natural language into formal logic using templates and provides verified results. It also analyzes source code call graphs for dead code, impact, and reachability.
