Claude Beta

Latest Audit Result

Claude Beta relies on exa-mcp-server (npm v3.2.1, plugin v3.3.9) at mcp.exa.ai. Default config enables only web_search_exa + web_fetch_exa. search and get_contents work; find_similar is not implemented; research tools exist but are deprecated and target a sunsetting /research endpoint. instant search type, summary, and subpages are available only via the disabled web_search_advanced_exa. Five deprecated API features (startCrawlDate/endCrawlDate, resolvedSearchType, highlightScores, /research endpoint) are still referenced in code despite being sunset per the April 1, 2026 Exa API changelog.

Missing Features (8)

• find_similar endpoint not implemented — no MCP tool maps to the Exa /findSimilar API
• DEPRECATED: startCrawlDate and endCrawlDate parameters still exposed in web_search_advanced_exa — silently ignored since April 15, hard removal May 1 per Exa API changelog
• DEPRECATED: resolvedSearchType still processed in response types and sanitizer — returns null since April 15, removal May 1
• DEPRECATED: highlightScores still processed in response types and sanitizer — returns null since April 15, removal May 1
• DEPRECATED: deep_researcher_start and deep_researcher_check still call /research/v1 — endpoint sunsetting May 1
• Claude Beta plugin config (client=claude-code-plugin) only enables web_search_exa + web_fetch_exa; instant search type, summary, and subpages require web_search_advanced_exa which is off by default
• web_search_exa hardcodes highlights:true but does not expose text, summary, or subpages content options — all four are configurable only via the disabled web_search_advanced_exa
• Version mismatch: .claude-plugin/plugin.json shows 3.3.9 while package.json shows 3.2.1
