mcp-ts-core vs mcp-server-elasticsearch

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.; mcp-server-elasticsearch: The Elasticsearch MCP Server enables AI agents to query, analyze, and retrieve data from Elasticsearch indices using natural language. It supports both stdio and streamable-HTTP protocols, and can be deployed as a Docker container from AWS Marketplace. Note: This server is deprecated and superseded by the Elastic Agent Builder MCP endpoint.
