Self-hosted Exa MCP alternatives
Exa's server can run locally over stdio, keeping the process and your key on your own machine. If you want that same arrangement against a different search or scraping backend, every server below also installs and runs on your side.
The caveat holds for all of them, Exa included: the search still hits an external API or the open web. Self-hosting controls where the server process and credentials sit, not whether the query leaves your network. The picks range from minimal lookups to full crawling.
The 8 best self-hosted alternatives
Firecrawl runs locally and turns sites into clean, LLM-ready data through scrape, crawl, map, search, and extract, far past Exa's search-and-read, from a process you control.
Set up Firecrawl →For research on your own machine, the arXiv server searches papers, downloads them, and reads full text as markdown over stdio, with semantic search and a citation graph.
Set up arXiv →Run Bright Data's server yourself for search and scraping that gets past blocks, CAPTCHAs, and geo-restrictions, the local option when target sites refuse plain requests.
Set up Bright Data →Tavily installs locally and adds extract, crawl, and map to real-time search, all built for AI, so one self-hosted process covers Exa's job and site-level reading.
Set up Tavily →The Apify server runs on your machine and exposes 6,000+ Actors plus run, dataset, and store tools for scraping and automating the web, well beyond search.
Set up Apify →DuckDuckGo's server runs locally and needs no API key, with just search and fetch_content, the minimal self-hosted option where Exa's neural search would be more than the task needs.
Set up DuckDuckGo →Brave's official server runs locally and returns web, news, image, video, and local results through one API, broader result types than Exa while staying on your machine.
Set up Brave Search →A privacy-leaning option with two focused tools, the Kagi server runs on your own machine and gives ad-free, privacy-respecting web search with clean full-page extraction.
Set up Kagi →
How to choose
All of these run on your hardware like Exa, so the process and keys stay local. DuckDuckGo and Kagi are the lightest, Kagi adding a privacy stance; Brave covers more result types; Firecrawl, Tavily, Bright Data, and Apify add crawling and extraction; arXiv handles papers. None of them, Exa included, keeps the query off the open web, since search reaches out by design.
FAQ
- Can the Exa MCP server be self-hosted?
- Yes. Exa offers a local server you run over stdio as well as a hosted endpoint, so you can keep the process and your API key on your own machine. Every alternative on this page also installs locally, so the self-hosted setup carries over.
- Does self-hosting a search server keep my queries on my network?
- No. Self-hosting keeps the server process and credentials on your infrastructure, but the search query still reaches an external API or the open web. That applies to Exa too. Kagi advertises privacy-respecting search if limiting what the query exposes matters.
