Provider, API, MCP, framework and protocol are different entities. These original source-linked notes are separate from the imported index and its counters; selection is editorial, not a performance ranking.
EDITORIAL · FRAMEWORK DOCUMENTATION · Agent frameworks
LangChain documents a framework for composing models, tools and agent behaviour. It is a software framework, not a universal hosted API endpoint.
