What Exa is

Exa is a search engine built for AI agents, used by Cursor, Claude, Codex, and others. Unlike scraping tools, Exa finds the right pages — ranking by semantic relevance across specialized indexes:

• 50M+ company pages with metadata (headcount, funding, revenue)
• 1B+ people profiles across LinkedIn and professional sources
• 100M+ research papers from arXiv, OpenReview, PubMed
• Plus news, financial reports (SEC filings), and personal sites

Benchmarks (exa-labs/benchmarks): Exa leads on RAG groundedness (79.4% vs Brave 76.3%, Tavily 61.1%), people search recall (R@10: 94.5% vs Brave 77.9%), and code content extraction (ROUGE-L: 83.2 vs next-best 73.7).

Recent launches: Exa Agent (June 2026), Exa Deep revamp (March 2026), Exa Instant (Feb 2026).

Plugin contents

6 skills + 1 MCP server + security rules:

Skill	What it does
exa-search	General web search + page reading
exa-research	Advanced search with category filters, domain/date restrictions, highlights
exa-company-research	Company discovery, competitive analysis, market research
exa-people-search	Find professionals by role, company, location, expertise
exa-code-search	Find code examples, API docs, library references
exa-fetch	Read any webpage as clean markdown

The MCP server at https://mcp.exa.ai/mcp authenticates via OAuth — no API key needed.

Notes for reviewers

Exa's MCP server is already widely adopted — it's a native Claude Connector, integrated in Cursor, VS Code, Codex, Windsurf, Zed, Gemini CLI, and others. The plugin includes 6 purpose-specific skills (company research, people search, code search, etc.) rather than one generic search skill, because Exa's category system is a differentiator that generic descriptions wouldn't surface.

Hey @ykeremy — adding the official Exa plugin to the marketplace. Exa is an AI search engine already integrated with Cursor, Claude, Codex, and others. The plugin repo is under the official exa-labs org and follows the same structure as the Firecrawl plugin. All checks pass locally. Would appreciate a review!

Updated the plugin with 6 differentiated skills (company research, people search, code search, etc.) instead of the initial 3 generic ones. Also bumped the pinned SHA and regenerated the index. All checks pass locally.
