exa-search

name	exa-search
description	Semantic web search, similar page discovery, and content extraction via Exa AI API. Use when the user needs meaning-based search (not keyword matching), wants to find pages similar to a URL, or needs clean content extraction from web pages. Requires EXA_API_KEY environment variable.

Exa Search

Exa is a semantic search engine built for AI. Unlike keyword search, Exa finds content by meaning using neural embeddings. It also provides clean content extraction and similarity search.

Prerequisites

Available Tools

This package provides three tools:

exa_search

Semantic web search. Finds pages by meaning, not keywords.

Key parameters:

• query — Natural language description of what you're looking for
• type — auto (default), fast (sub-350ms), neural, deep (multi-step reasoning)
• category — Filter: company, research paper, news, tweet, personal site, financial report
• includeDomains / excludeDomains — Domain filtering
• startPublishedDate / endPublishedDate — Date range (ISO 8601)
• includeText — Get full page text
• includeSummary — Get AI-generated summary
• includeHighlights — Get relevant excerpts (default: true)
• numResults — Result count (default: 10, max: 100)

exa_find_similar

Find pages semantically similar to a given URL. Good for competitor analysis, related content, and "more like this" discovery.

Key parameters:

• url — The URL to find similar pages for
• numResults, includeDomains, excludeDomains, date filters — Same as search
• excludeText — Exclude results containing specific text

exa_get_contents

Extract clean, parsed content from one or more URLs. More reliable than raw scraping.

Key parameters:

• urls — Array of URLs to extract
• includeText — Full page text (default: true)
• includeSummary — AI summary
• includeHighlights — Key excerpts
• maxTextCharacters — Max characters per page (default: 5000)
