registry vs mcp

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.; mcp: This MCP server uses pre-computed code graphs to provide sub-second responses for symbol lookups, call-graph traversal, and cross-subsystem analysis. It integrates with AI agents via the Model Context Protocol, offering both default symbol context mode and experimental GraphRAG mode for deeper code exploration. The server supports caching for fast performance and works with popular MCP clients like Claude Code CLI and Cursor.
