Developers ship Erlang and Python MCP implementations and toolnexus provider-agnostic toolkit

According to GitHub repositories, developers are shipping new MCP implementations including erlangchain, a minimal Erlang LLM client with OpenAI and Anthropic support requiring only OTP dependencies, and a Python port of toolnexus. Toolnexus is a provider-agnostic toolkit for building agents that unifies MCP servers, agent skills, and HTTP endpoints with built-in tools including bash, file read, grep, and web fetch.
