概覽

AI 產生的概覽

Exa 託管的 MCP 伺服器，讓助理搜尋網頁並以乾淨的 Markdown 取得整頁內容，用於研究。

可以做什麼
  • 依任意主題搜尋網頁，回傳排名前面結果的乾淨文字，並建議描述理想頁面而非關鍵字
  • 以乾淨的 Markdown 讀取一個或多個已知網址的完整內容與中繼資料，可在單次呼叫中批次處理
  • 可透過伺服器網址啟用選用工具：含網域、日期、重點標示、摘要與子頁面篩選的進階搜尋，以及用於多步驟研究、名單建立、資料充實與結構化輸出的 Exa Agent
適用情境
適合助理需要從即時網路取得最新資訊、新聞、事實、人物或公司資料，或需要讀取特定頁面全文的情境。選用的進階搜尋與 Agent 工具適合深度研究、潛在客戶開發與競品分析。
執行需求
遠端 streamable HTTP 端點，不需本機套件或執行環境。可匿名使用但有速率限制。更高額度及 Exa Agent 需要 OAuth 登入或 Exa API 金鑰，可透過網址參數或 Authorization Bearer、x-api-key 標頭傳入。選用工具需附加到 MCP 網址後啟用，這會取代預設工具。
安裝前請注意
匿名使用受速率限制，頻繁使用需 Exa 帳號與憑證。把 API 金鑰放在網址查詢參數中可能經由日誌或共用設定外洩，建議優先使用 OAuth 或標頭。搜尋查詢與抓取的網址會傳送到 Exa 的託管服務。透過網址啟用選用工具會取代預設工具，需列出所有需要的工具。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Exa，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/ai.exa%2Fexa/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

Available Tools

Default Tools

ToolDescription
web_search_exaSearch the web for any topic and get clean, ready-to-use content
web_fetch_exaRead a webpage's full content as clean markdown from one or more URLs

Optional Tools (enable via the tools parameter)

ToolDescription

web_search_advanced_exaAdvanced search with filters, domains, dates, highlights, summaries, and subpage crawling

Enable tools by appending them to the MCP URL (this will replace the defaults, so include all you want):

https://mcp.exa.ai/mcp?tools=web_search_advanced_exahttps://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_run

Exa Agent requires authentication (OAuth or an API key).

Agent Skills

Skills live in skills/ and load with Agent Plugin installs. The Claude plugin in plugins/exa/ ships a copy of them; npm test fails when the copy drifts. Each package version bump on main publishes plugins/exa/ to the root of the claude-plugin branch, which Claude's plugin directory reads. To publish a plugin-only change between releases, run the Publish Claude plugin workflow manually.

SkillPathUse when
searchskills/search/Deep research, lead gen, competitive analysis, multi-step web investigation
exa-agentskills/exa-agent/Exa Agent runs, enrichment, structured output, Connect providers

Invoke from your client's skill UI (or /skill-name where supported). MCP-only setups still get the tools; skills add orchestration on top.

Authentication

The hosted MCP server works anonymously with rate limits. For higher limits and access to Exa Agent, use either OAuth or an API key.

OAuth is preferred: most clients prompt you to sign in to Exa. To force the login flow (useful for shared connectors and plugins), use https://mcp.exa.ai/mcp?login or https://mcp.exa.ai/mcp/oauth.

If you prefer, you can get an API key from the dashboard and pass it on the URL as ?exaApiKey=…. You can also send it as a Authorization: Bearer … header or an x-api-key header.
