Exa Web Search (Free)

What It Does

Advanced tools like deep search, page crawling, and people search are available by switching to the full endpoint.

Exa Web Search (Free) brings neural search capabilities to your AI agent without requiring any API key. It exposes three ready-to-use tools covering general web search, code and documentation lookup (GitHub, Stack Overflow), and company research — all routed through Exa's MCP server via `mcporter`.

Key Features

• No API Key Required — The free tier connects directly to `https://mcp.exa.ai/mcp` through `mcporter` with no credentials needed. Get started immediately after a single config command.
• Neural Web Search (`web_search_exa`) — Search the live web for current events, news, and factual queries. Supports `auto`, `fast`, and `deep` search modes so you can trade speed for thoroughness depending on your use case.
• Code & Documentation Search (`get_code_context_exa`) — Retrieves code examples and API documentation from developer sources like GitHub and Stack Overflow. The `tokensNum` parameter (1,000–50,000) lets you control result depth from focused snippets to comprehensive references.
• Company Research (`company_research_exa`) — Looks up business information, recent news, and background details for any company by name. Useful for competitive research, due diligence, or staying informed about key players in a space.
• Optional Advanced Tool Suite — Unlock six additional tools — including domain/date-filtered search, query expansion, full-page crawling, professional profile lookup, and an AI-driven deep research agent — by pointing `mcporter` at the extended endpoint URL.

Use Cases

• Daily news and current events briefing — Use `web_search_exa` with `type: "deep"` to gather the latest developments on any topic — AI research, markets, geopolitics — and have your agent summarize or synthesize the results.
• Code example discovery during development — When working with an unfamiliar library or API, call `get_code_context_exa` to pull relevant snippets and documentation from GitHub and Stack Overflow, reducing time spent manually searching.
• Competitive and business intelligence — Call `company_research_exa` with a competitor or partner name to surface recent news, product announcements, and background — useful before meetings, pitches, or strategic planning.
• Deep research on complex topics — Enable the full tool suite and use `deep_researcher_start` / `deep_researcher_check` to kick off an AI-driven multi-step research job on broad or nuanced questions, with results returned asynchronously.
