Frequently Asked Questions
Can I use multiple search MCPs at once?
Yes. Many developers run both Brave Search and Tavily. Your AI chooses the best one based on the query.
Which search MCP does the best job with code documentation?
Tavily — its AI-optimized results are clean and well-structured, making it easier for AI to extract relevant code examples from docs.
Is there a Google Search MCP?
Yes — there are community-built Google Search MCPs, but they require a Google Custom Search Engine API key and have strict rate limits. Brave and Tavily are better alternatives for most use cases.
