Connect Claude, Cursor, or any MCP-compatible client — then call tools directly

① Add This MCP Server

Paste into your AI client config — then all its tools are available instantly.

.claude/mcp.json

{
  "mcpServers": {
    "exa": {
      "url": "https://mcp.aerostack.dev/s/aerostack/mcp-exa",
      "headers": {
        "Authorization": "Bearer YOUR_AEROSTACK_TOKEN"

    }
  }
}

Replace YOUR_AEROSTACK_TOKEN with your API token from the dashboard.

② Call a Tool

Ask your AI assistant to call a specific tool, or send raw JSON-RPC:

Natural Language Prompt

“Use the _ping tool to verify exa api connectivity. used internally by aerostack to validate credentials”

Using a Workspace?

Add this MCP to your Workspace — your team shares one token, secrets are stored securely, and every AI agent in the workspace can call it without per-user setup.

description Overview

mcp-exa — Exa MCP Server

Semantic web search, page scraping, and similarity discovery for AI agents.

Exa is a search engine built for AI — it understands meaning, not just keywords. This MCP server lets your AI agents search the web semantically, scrape full page contents, and find similar pages to any URL. Perfect for RAG pipelines, research agents, competitive analysis, and content discovery workflows.

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-exa

What You Can Do

Search the web using natural language queries with semantic understanding — far better than keyword matching for AI use cases
Scrape and extract clean text from any web page, with optional highlights and AI-generated summaries
Find pages similar to a given URL for competitive research, alternative discovery, or content clustering
Combine search + scrape in a single call to build RAG pipelines with minimal latency
Filter results by domain, date range, and content category (news, research papers, GitHub repos, tweets, etc.)

Available Tools

Tool	Description
`_ping`	Verify Exa API connectivity (used internally by Aerostack)
`search`	Semantic or keyword web search with filters for domains, dates, and categories
`get_contents`	Get full text, highlights, or summaries from one or more URLs
`find_similar`	Find web pages similar to a given URL
`search_and_contents`	Combined search + content extraction in one call

Configuration

Variable	Required	Description	How to Get
`EXA_API_KEY`	Yes	Exa API key for authentication	dashboard.exa.ai → API Keys → create or copy key

Quick Start

Add to Aerostack Workspace

Go to aerostack.dev → Your Project → MCPs
Search for "Exa" and click Add to Workspace
Add EXA_API_KEY under Project → Secrets

Once added, every AI agent in your workspace can call Exa tools automatically — no per-user setup needed.

Frequently asked questions

What is the Exa MCP server and what can it do? +

The Exa MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `search`, `get_contents`, `find_similar`, `search_and_contents`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.

Is the Exa MCP server hosted, or do I have to run it myself? +

It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.

Which AI agents and editors can use the Exa MCP server? +

Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same Exa MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.

How do I install the Exa MCP server in Claude Desktop? +

Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-exa": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-exa"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.

How do I use the Exa MCP server in Cursor? +

In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-exa", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-exa"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.

Does Exa MCP require authentication? +

Yes. Exa requires authentication. Check the MCP's documentation for the required credentials.
