Best MCP servers for web search
An agent is only as current as the information it can reach, and its training data has a cutoff. Web search is what closes that gap: the ability to run a live query, read the results, and ground an answer in what the internet says right now rather than what the model memorized months ago. The right server depends on what you value, raw search-API coverage, results pre-cleaned for LLM consumption, an opinionated answer engine, or a privacy-respecting index, but the recurring need is the same: let the agent search the open web and pull back usable text. The servers below cover the common shapes, each a real MCP server with a verified, current install config.
Brave Search

Exa
Exa
Exa's official server gives agents neural web search and clean full-page content built for LLMs.
