mcp-ts-core and mcp-streamable-http
The TypeScript template for building MCP servers and the example implementation of MCP Streamable HTTP are complements, as the former provides a foundational framework for server development while the latter offers a specific pattern for handling HTTP streams within the MCP ecosystem, which can be integrated into servers built with the template.
About mcp-ts-core
cyanheads/mcp-ts-core
TypeScript template for building Model Context Protocol (MCP) servers. Ships with declarative tools/resources, pluggable auth, multi-backend storage, OpenTelemetry observability, and first-class support for both local and edge (Cloudflare Workers) runtimes.
Built on the MCP SDK, it provides a dependency library rather than a fork—handlers receive a unified context object (`ctx`) with request-scoped logging, tenant storage, LLM sampling, and cancellation signals. The framework automates transport setup (stdio/HTTP/Workers), validates definitions against the MCP spec at startup, and classifies errors into standard categories without instrumentation code. Multi-backend storage (in-memory, filesystem, Supabase, Cloudflare D1/KV/R2), pluggable auth (JWT/OAuth), and OpenTelemetry observability are configured via environment variables, with optional peer dependencies for parsers, OTEL SDK, and cloud providers.
About mcp-streamable-http
invariantlabs-ai/mcp-streamable-http
Example implementation of MCP Streamable HTTP client/server in Python and TypeScript.
Provides complete cross-language MCP Streamable HTTP implementations demonstrating bidirectional communication between Python and TypeScript clients/servers over HTTP. Features an interactive chat interface that integrates with Anthropic's Claude API, routing tool calls through a local MCP weather server. Implements the MCP Streamable HTTP transport specification for real-time, request-response protocol exchanges.
