已验证Streamable HTTP可网页运行网页搜索与抓取知识与记忆

概览

AI 生成的概览

Exa 托管的 MCP 服务器，让助手搜索网页并以干净的 Markdown 获取整页内容，用于研究。

可以做什么
  • 按任意主题搜索网页，返回排名靠前结果的干净文本，并建议描述理想页面而非关键词
  • 以干净的 Markdown 读取一个或多个已知网址的完整内容及元数据，可在一次调用中批量处理
  • 可通过服务器网址启用可选工具：带域名、日期、高亮、摘要和子页面筛选的高级搜索，以及用于多步研究、名单构建、信息补全和结构化输出的 Exa Agent
适用场景
适合助手需要从实时网络获取最新信息、新闻、事实、人物或公司资料，或需要读取特定页面全文的场景。可选的高级搜索与 Agent 工具适合深度研究、线索获取和竞品分析。
运行要求
远程 streamable HTTP 端点，无需本地包或运行时。匿名可用但有速率限制。更高额度及 Exa Agent 需要 OAuth 登录或 Exa API 密钥，可通过网址参数或 Authorization Bearer、x-api-key 请求头传入。可选工具需追加到 MCP 网址后启用，这会替换默认工具。
安装前请注意
匿名使用受速率限制，频繁使用需 Exa 账号和凭据。把 API 密钥放在网址查询参数中可能通过日志或共享配置泄露，建议优先使用 OAuth 或请求头。搜索查询和抓取的网址会发送到 Exa 的托管服务。通过网址启用可选工具会替换默认工具，需列出所有需要的工具。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Exa，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/ai.exa%2Fexa/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

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
agent_runRun an Exa Agent for multi-step research, list-building, enrichment, and structured output
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.
