Context7 MCP
Up-to-date library documentation for coding agents via MCP.
About
Context7 (upstash/context7, MIT, ~63k stars) is the MCP server that feeds coding agents current library docs: instead of relying on stale training data, the agent fetches fresh documentation for the exact library version in use.
One of the most-installed MCP servers in existence. Add it to your MCP config once and every agent session gets accurate, version-correct docs. Near-essential infrastructure for agentic coding.
What it can do
