mcp-ts-core vs ARBuilder

mcp-ts-core: @cyanheads/mcp-ts-core is a TypeScript framework for building MCP servers. It offers declarative tool/resource/prompt definitions with Zod schemas, pluggable authentication, multi-backend storage, OpenTelemetry observability, and runs on both local (stdio/HTTP) and edge (Cloudflare Workers) runtimes. The framework handles infrastructure concerns like transport, auth, storage, config, logging, and lifecycle, so developers can focus on writing business logic.; ARBuilder: ARBuilder is an AI-powered development assistant for the Arbitrum ecosystem. It transforms natural language prompts into Stylus smart contracts, cross-chain SDK implementations, full-stack dApps, and Orbit chain deployment assistance. It uses a RAG pipeline with hybrid search and provides MCP server integration for IDEs.
