MCP servers that search documentation
Feed the AI up-to-date library & API docs to cut hallucinated APIs.
7 servers · Last updated June 17, 2026
TL;DR: These servers pull current documentation for libraries and APIs into the agent's context, so it stops inventing methods that don't exist. They're one of the highest-leverage additions for any coding agent — version-correct docs beat stale training data every time.
Bottom line: if you only try one, Context7 MCP Server is the most popular, verified option for this (28,000★). 6 more compared below.

FAQ
Why add a docs MCP to a coding agent?
LLM training data lags library releases. A docs server (e.g. Context7, GitMCP) injects current, version-correct API docs so the agent stops hallucinating methods.
Do these cover private/internal docs?
Some can index a specific repo or site; others target public package docs. Check each server's scope on its page.
