Search MCP Servers

The Apify MCP server gives AI agents access to 6,000+ ready-made cloud scrapers, crawlers, and automation tools on the Apify Store — no infrastructure required. Connect to Apify Actors that extract data from social media platforms (Instagram, TikTok, LinkedIn), search engines (Google, Bing), e-commerce sites (Amazon, eBay), maps (Google Maps), and virtually any website. Each Actor runs in the cloud with managed proxies, browser fingerprinting, and anti-bot bypass built in. Use the Apify MCP server to query Actors by task, stream results directly into your AI context, run custom scraping Actors from your Apify account, and chain multiple data extraction steps in a single workflow. Supports tool filtering to expose only the Actors you need, and integrates with Apify's RAG web browser Actor for retrieval-augmented generation use cases.

The Firecrawl MCP server gives your AI assistant the ability to crawl, scrape, and extract structured data from any website — turning raw HTML into clean, LLM-ready Markdown or JSON in seconds. Built by the Firecrawl team, it exposes tools for single-page scraping, deep site crawls (following internal links), and batch URL extraction, all with JavaScript rendering handled automatically so dynamic content is never missed. Developers use it to automate competitive research, build live knowledge bases, extract pricing tables, monitor documentation changes, or feed structured web data into RAG pipelines — all through natural-language prompts without writing a single scraper script. The Firecrawl MCP server handles rate limiting, retries, and proxy rotation behind the scenes. Authentication requires a Firecrawl API key (free tier available). Install with: npx firecrawl-mcp. Works with Claude Desktop, Cursor, VS Code, and any MCP-compatible client. With Firecrawl, any public webpage becomes a structured data source your AI can reason over, compare, and act on — making it the go-to MCP server for web data extraction workflows.

Exa's official MCP server connects AI assistants to a search engine purpose-built for AI, using neural embeddings to match on meaning rather than keywords so agents get clean, ready-to-use content instead of a page of blue links to re-parse. The default tool set covers web_search_exa for quick topical lookups and web_search_advanced_exa for full control over domains, date ranges, and content filters, plus specialized tools for code_search (searching real-world code and GitHub), company_research (building company profiles, competitor lists, and financials), crawling/web_fetch (pulling clean content from a specific URL), people_search and linkedin_search (public professional-profile lookups), and deep_researcher_start/check for long-running multi-step research tasks backed by Exa's Research API. The server is hosted at https://mcp.exa.ai/mcp — no local process to run — and connects via one-line setup in Cursor, VS Code, Claude Code, Claude Desktop (available as a native Connector), Codex, OpenCode, Windsurf, and Antigravity, authenticated with an EXA_API_KEY from the Exa dashboard. Tool exposure is tunable per client via a ?tools= query parameter on the endpoint URL, letting teams ship narrow, purpose-built configurations (e.g. company-research-only or LinkedIn-only agents) instead of exposing the full surface, and Exa ships ready-made Claude Skills/agent definitions for common patterns like company research and people search with built-in query-variation and token-isolation guidance.

The Brave Search MCP Server is the official server from Brave that gives AI assistants privacy-first web search through the independent Brave Search API — no tracking, no profiling, and results drawn from Brave's own web index rather than Google or Bing. It exposes five distinct tools that map directly to the Brave Search API endpoints: brave_web_search for general queries with pagination, freshness filters, and safe-search controls; brave_local_search for businesses, restaurants, and points of interest with automatic location filtering; brave_news_search for recent articles and current events; brave_image_search for image discovery; and brave_video_search for finding videos across the web. Authentication uses a single BRAVE_API_KEY (free tier available at brave.com/search/api) or a mounted BRAVE_API_KEY_FILE for Docker-secret setups. Install in Claude Desktop, Cursor, Windsurf, or VS Code with one npx command and choose stdio or streamable-HTTP transport. Because Brave operates its own crawler and index, the Brave Search MCP server is a strong choice for developers who want an alternative to Google-dependent search tools, need reproducible non-personalized results, or care about data privacy in agent workflows — Claude can pull fresh web context, verify facts, and research topics without leaking queries to ad-tech pipelines.

The Elasticsearch MCP Server (elastic/mcp-server-elasticsearch) is Elastic's official server for connecting AI agents to Elasticsearch data over the Model Context Protocol, enabling natural-language querying, analysis, and retrieval across your indices without building custom APIs. Once connected, an assistant can list available indices, inspect field mappings, and run searches or aggregations described in plain English — "show me the top error messages from the last 24 hours" — against an Elasticsearch 8.x or 9.x cluster. Important status note: as of version 0.4.0 this standalone server is officially DEPRECATED and receives only critical security updates going forward; Elastic has superseded it with the Elastic Agent Builder MCP endpoint, available in Elastic 9.2.0+ and Elasticsearch Serverless projects, which is the recommended path for new integrations. For existing users, the current server ships as a Docker container image (docker.elastic.co/mcp/elasticsearch) rather than a pip package, and supports both stdio and streamable-HTTP transports (SSE is deprecated). Configure it with the `ES_URL` environment variable pointing at your cluster plus either an `ES_API_KEY` or an `ES_USERNAME`/`ES_PASSWORD` pair for authentication; an optional `ES_SSL_SKIP_VERIFY=true` is available for development-only TLS bypass. Run in stdio mode with `docker run -i --rm -e ES_URL -e ES_API_KEY docker.elastic.co/mcp/elasticsearch stdio` and add the equivalent block to your Claude Desktop, Cursor, or VS Code MCP config.

The YouTube MCP Server by Zubeid Hendricks connects AI assistants to the full YouTube Data API v3, letting Claude search videos, pull transcripts, manage content, and run analytics without leaving the conversation. It is one of the most complete community YouTube MCP servers, exposing tools across several areas: video management (search by keyword, retrieve metadata, get statistics, and list a channel's uploads), transcript retrieval (fetch full captions for any public video for summarization or Q&A), channel operations (look up channel details, subscriber and view counts, and recent activity), playlist tools (list and inspect playlist contents), Shorts creation workflows, and advanced analytics for creators tracking performance. Authentication uses a single YOUTUBE_API_KEY obtained free from the Google Cloud Console by enabling the YouTube Data API v3 — read-heavy operations fit comfortably inside the daily quota. Install globally with npm as zubeid-youtube-mcp-server, run it directly with npx (no install required), or add it through Smithery for one-click Claude Desktop setup; a Docker image is also provided for HTTP transport. The YouTube MCP Server is ideal for content research, competitive analysis, transcript-based summarization, and automated creator workflows — Claude can, for example, find the top videos on a topic, fetch their transcripts, and synthesize a briefing in a single pass.

Weaviate's Model Context Protocol support has moved from a separate add-on into the core Weaviate database itself: as of v1.37.1, every Weaviate instance ships a built-in MCP server that AI assistants like Claude Desktop, Cursor, and Windsurf can connect to directly, with no standalone process to install or maintain. Enabling it is a single environment variable, `MCP_SERVER_ENABLED=true`, on the Weaviate server; the MCP endpoint then listens on the same port as the existing REST API at `/v1/mcp`, reuses Weaviate's existing API-key authentication, and respects the same RBAC permissions already configured for the cluster — so there is no separate credential or trust boundary to manage. Exposed tools cover the core vector-database workflow an AI agent needs: `weaviate-collections-get-config` inspects collection schemas, `weaviate-tenants-list` enumerates tenants in multi-tenant collections, `weaviate-query-hybrid` runs combined vector-plus-keyword hybrid search, and `weaviate-objects-upsert` creates or updates objects. The earlier standalone Go implementation that used to live in the weaviate/mcp-server-weaviate repository is now deprecated and unmaintained — its git history is kept only for reference — so teams should configure MCP through the main weaviate/weaviate server rather than looking for a separate package to install. Full setup, environment variables, and per-tool RBAC permission mapping are documented at docs.weaviate.io/weaviate/configuration/mcp-server.

The official Qdrant MCP server (qdrant/mcp-server-qdrant) turns the Qdrant vector search engine into a semantic memory layer for AI assistants like Claude Desktop, Cursor, and Windsurf. Built on FastMCP, it exposes two core tools: `qdrant-store`, which embeds and saves a piece of text plus optional JSON metadata into a named Qdrant collection, and `qdrant-find`, which runs a semantic similarity search over a collection and returns the most relevant stored entries. Together they let an AI agent persist facts, code snippets, or past conversation context and recall them later by meaning rather than exact keywords — a lightweight long-term memory that survives across sessions. Configuration is entirely environment-variable driven: point `QDRANT_URL` and `QDRANT_API_KEY` at a Qdrant Cloud cluster or self-hosted instance, or use `QDRANT_LOCAL_PATH` to run against an embedded on-disk database with no server. `COLLECTION_NAME` sets a default collection, `EMBEDDING_MODEL` selects the FastEmbed sentence-transformer used to vectorize text (default sentence-transformers/all-MiniLM-L6-v2), and `QDRANT_READ_ONLY` disables the store tool for query-only deployments. Install with `uvx mcp-server-qdrant` (Python/PyPI) and choose stdio or SSE transport via the `--transport` flag. With 1,450+ GitHub stars it is the reference implementation for giving coding agents durable semantic memory.

A clean, LLM-optimized MCP server that lets Claude Desktop and other AI assistants browse Reddit, search posts, and analyze user activity with zero setup and no Reddit API registration required. Core tools include `browse_subreddit` (hot/new/top/rising/controversial sorting across any subreddit, "all", or "popular", with time-range filters), `search_reddit` (query across all of Reddit or a specific subreddit, filterable by author/time/flair, sortable by relevance/hot/top/new/comments), `get_post_details` (fetch a post plus its full comment thread from a Reddit URL in any format — reddit.com, old./new./np./m.reddit.com, or redd.it short links — or from a bare post ID), and `user_analysis` (karma, post/comment history, and active subreddits for any username). A three-tier authentication system scales from 10 requests/minute with zero config up to 100 requests/minute when Reddit API credentials are supplied, so it works instantly out of the box and scales up for heavier use. The project deliberately avoids fabricated "sentiment analysis" or made-up metrics, focusing on clean, structured Reddit data formatted for LLM consumption. Install as a Claude Desktop Extension (.mcpb one-click download), via NPM (`npx -y reddit-mcp-buddy`), or through the official MCP Registry — it is fully TypeScript, actively maintained, and one of the most-starred Reddit MCP integrations available.

The Hacker News MCP server gives Claude, Cursor, and other MCP clients live access to Hacker News so an AI assistant can pull the latest stories, comment threads, and user profiles into a conversation. This community server (paabloLC/mcp-hacker-news, TypeScript) acts as a thin, well-behaved bridge over the official Firebase-backed Hacker News API — it does not scrape the site, so results match what you see on news.ycombinator.com. It exposes standard MCP tools for fetching top, new, best, Ask HN, Show HN, and job stories, retrieving a specific item with its nested comment tree, and looking up a user's karma, bio, and submission history. That makes it useful for tracking what is trending in the developer and startup community, summarizing long comment discussions, monitoring a launch or a topic, or feeding fresh HN context into research and content workflows. Installation is zero-config: point your client at `npx -y mcp-hacker-news` (Node.js 18+ required) and it runs over stdio with no API key or authentication, since the Hacker News API is public and read-only. Note this is a lower-star community project rather than an official Y Combinator release — it is a lightweight, dependency-free option that is easy to audit and self-host if you prefer.

The Product Hunt MCP Server connects Claude, Cursor, and other MCP clients directly to Product Hunt's official GraphQL API, letting an AI assistant look up launches, collections, topics, users, votes, and comments without leaving the conversation. Built with FastMCP for speed, the server exposes tools to fetch detailed post info (tagline, description, vote count, maker list, comments), search and filter launches by topic, date range, or vote threshold, page through paginated comment threads and a user's upvote history, and pull collection and topic metadata. It is a good fit for AI-agent workflows that need to research competitor launches, track a specific topic's daily leaderboard, summarize maker comments, or build a "what shipped today" digest inside an agent pipeline. Authentication uses a personal Product Hunt Developer Token generated from the Product Hunt API Dashboard (any placeholder redirect_uri works, since the MCP server never uses an OAuth redirect flow itself) supplied via the PRODUCT_HUNT_TOKEN environment variable. Install with `pip install product-hunt-mcp` or `uv pip install product-hunt-mcp`; a Docker image and a git+https install path are also documented for teams that prefer container-based MCP deployments. Config for Claude Desktop or Cursor just points the command at the installed `product-hunt-mcp` binary with the token set in the env block.

The arXiv MCP Server bridges AI assistants to arXiv's research repository through the Model Context Protocol, letting Claude, Cursor, VS Code, and other MCP clients search, download, and read academic papers directly inside a conversation. The core workflow is search_papers → download_paper → read_paper: search_papers queries arXiv with boolean, category (cs.AI, cs.LG, cs.CL, cs.CV, stat.ML, quant-ph, and more), and date-range filters while automatically respecting arXiv's 3-second rate limit; download_paper fetches a paper by its arXiv ID (HTML first, PDF fallback) and stores it locally, returning content_length/next_start metadata so clients can safely page through very large papers; read_paper then returns the full text as markdown, with start/max_chars pagination for long documents. list_papers shows everything downloaded locally, and semantic_search searches across that local collection. The server also ships a "deep-paper-analysis" prompt that walks an assistant through executive summary, methodology, results, and future-research-direction analysis for a given paper ID. Install with `uv tool install arxiv-mcp-server` (NOT npm — an unrelated third-party package squats the same name on npm) or via the one-click Claude Desktop .mcpb bundle; a Streamable HTTP transport is available for server deployments. The README explicitly flags that arXiv paper content is untrusted external input and warns about prompt-injection risk (OWASP LLM01/AG01) when feeding raw paper text into agentic pipelines with tool access.

The Semantic Scholar MCP Server is a FastMCP-based Python server that connects Claude, Cursor, VS Code, and other MCP clients to the Semantic Scholar API — the Allen Institute for AI's corpus of 200M+ academic papers — so an assistant can search literature, trace citation networks, and pull author profiles directly inside a conversation instead of guessing from training data. On the paper side it exposes full-text and title-based search with advanced filtering, multi-strategy ranked search, single- and multi-paper recommendations, and efficient batch detail retrieval with customizable field selection. Its citation-analysis tools walk the citation graph in both directions — citations and references — with citation context and influence signals, which is what makes it a strong fit for literature-review and citation-tracing agents rather than one-off lookups. Author tools cover author search, profile details, publication history, and batch author retrieval. It works unauthenticated for light use, but setting a SEMANTIC_SCHOLAR_API_KEY environment variable raises rate limits for heavier workflows; the server handles rate-limit compliance, connection pooling, and graceful shutdown internally. Install with `pip install semantic-scholar-fastmcp` or run it with no install via `uvx semantic-scholar-fastmcp`, then point your client's config at the uvx command. A Smithery one-click install for Claude Desktop and a companion Claude Code skills bundle (expand-references, trace-citations, paper-triage) are also available. Requires Python 3.10+.

This Wolfram Alpha MCP server gives AI assistants a direct line to the Wolfram|Alpha computational knowledge engine, letting them run math, science, unit-conversion, and structured data queries and get back verified answers instead of guessing at arithmetic or facts. It wraps the Wolfram|Alpha API in an MCP-compliant interface with a modular architecture designed to be extended to additional Wolfram APIs and multi-client setups. Beyond the server itself, the project bundles an example MCP client built on Gemini via LangChain, plus an optional Gradio web UI for interacting with both Google AI and the Wolfram Alpha MCP server side by side — useful for testing queries before wiring the server into Claude Desktop, Cursor, or VS Code. Configuration requires a WOLFRAM_API_KEY (a free Wolfram|Alpha AppID) set via a .env file, and an optional GeminiAPI key if using the bundled LangChain client. Install by cloning the repo and running `pip install -r requirements.txt` (or `uv sync`), then point your MCP client at the packaged server.py entry point; a VS Code MCP config template and Docker build files for the client/UI are included in the repo. Because Wolfram|Alpha handles the actual computation server-side, this server is a strong fit for agentic workflows that need reliably correct math or unit conversions rather than LLM-generated approximations.

The Perplexity MCP Server is the official server from Perplexity AI that brings real-time web search, reasoning, and deep research into any MCP-compatible client through the Perplexity Sonar API. Unlike scrapers or search-index wrappers, it taps Perplexity's own answer engine, so Claude gets grounded, citation-backed responses drawn from live web results. The server exposes four purpose-built tools: perplexity_search returns ranked web results with snippets for lightweight lookups; perplexity_ask provides general-purpose conversational answers with real-time search using the sonar-pro model, ideal for quick everyday questions; perplexity_research runs deep, comprehensive investigations with the sonar-deep-research model for thorough analysis and detailed reports; and perplexity_reason handles advanced problem-solving and multi-step analytical tasks with the sonar-reasoning-pro model, with an optional strip_thinking parameter to control chain-of-thought output. Authentication uses a single PERPLEXITY_API_KEY from the Perplexity API dashboard. Installation is a one-line npx command with the official @perplexity-ai/mcp-server package — add it to Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, or Codex, with a Docker image and HTTP transport also supported for server deployments. Because it is Perplexity's first-party implementation (2,300+ GitHub stars), the Perplexity MCP Server is the most reliable way to give an AI agent fresh, sourced answers — perfect for research assistants, fact-checking, and any workflow that needs current information the base model was never trained on.

The Tavily MCP server (tavily-ai/tavily-mcp) is the official, production-ready Model Context Protocol server for Tavily, a search API built specifically for AI agents and RAG pipelines rather than human browsing. It exposes four tools: tavily-search runs real-time web searches tuned for LLM consumption (returning clean, ranked, source-cited results instead of raw HTML), tavily-extract pulls the full clean content out of one or more specific URLs, tavily-map builds a structured map of a site's pages starting from a root URL, and tavily-crawl walks a site to gather content across many pages in a single call. Together these let an assistant answer "search for the latest changelog entries for library X and summarize the breaking changes" or "extract the pricing table from these three competitor pages" with grounded, up-to-date, citation-backed data instead of stale training knowledge. Authentication uses a single `TAVILY_API_KEY` from tavily.com (a generous free tier is available). You can run it locally with `npx -y tavily-mcp@latest` in your Claude Desktop, Cursor, Windsurf, or Cline config, or connect to Tavily's hosted remote server at mcp.tavily.com for a zero-install setup. Typical use: give a coding or research agent live web access so it can verify facts, read documentation it has never seen, and cite real sources — one of the most widely adopted search servers in the MCP ecosystem.

Community-built MCP server that gives AI agents live Google Search and webpage scraping through the Serper API — a fast, low-cost alternative to Google's own Custom Search. Exposes two tools: `google_search`, which returns rich SERP data (organic results, knowledge graph, 'people also ask', related searches) with region and language targeting, pagination, time filters, autocorrection, and full Google advanced-operator support (site:, filetype:, inurl:, intitle:, related:, before:/after: date ranges, exact-phrase, exclusion, and OR alternatives); and `scrape`, which extracts clean plain-text or markdown content from any URL along with JSON-LD structured data and head metadata while preserving document structure. Written in TypeScript and distributed on npm as `serper-search-scrape-mcp-server` (also available via Smithery for one-command Claude Desktop setup). Requires a Serper API key set as the `SERPER_API_KEY` environment variable; Serper's free tier of 2,500 queries makes it popular for prototyping RAG and research agents. Ideal for grounding LLM answers in current web results, competitive research, fact-checking, and building agents that need to both search and read pages without wiring up separate search and scraping providers.

The You.com MCP Server (published as `@youdotcom-oss/mcp`) is a lightweight STDIO bridge that proxies MCP clients to You.com's hosted MCP endpoint at `https://api.you.com/mcp`, rather than running search logic locally — the actual retrieval and ranking happen on You.com's servers. It ships from You.com's own `youdotcom-oss` GitHub organization as part of their dx-toolkit monorepo, not the fabricated `you-com/mcp-server` repo sometimes cited elsewhere. Install by running `npx @youdotcom-oss/mcp` directly in your MCP client config, or add it as a dependency with `bun add @youdotcom-oss/mcp`; authentication requires a `YDC_API_KEY` environment variable, sent as a Bearer token to the hosted endpoint. By default the server exposes three tools: `you-search` for real-time web search grounded in You.com's independent index, `you-research` for deeper multi-step research queries that synthesize across several sources, and `you-contents` for fetching and extracting clean content from specific URLs. A fourth tool, `you-finance`, covers stock/market data but is opt-in only — it must be explicitly added via the `YDC_ALLOWED_TOOLS` environment variable (e.g. `YDC_ALLOWED_TOOLS=you-search,you-finance`) rather than being enabled by default. Typical use: an agent needs current information beyond its training cutoff — "search for the latest news on X" or "research competing products in this space and summarize the differences" — and calls You.com's search/research tools instead of relying on stale internal knowledge or a generic scraping fallback.

Search the web using Kagi's search API.

najva-ai's Sourcegraph MCP Server is a Python server that gives AI assistants AI-enhanced code search across large, multi-repo codebases using Sourcegraph's query engine. It exposes three tools: `search` (run Sourcegraph queries with full advanced syntax — regex patterns, `lang:`/`file:`/`repo:` filters, and boolean operators — across sourcegraph.com or a self-hosted instance), `search_prompt_guide` (generate a context-aware guide that helps the model construct effective queries for a stated objective), and `fetch_content` (retrieve file contents or explore directory structures inside a repository). Auth is via a `SRC_ENDPOINT` environment variable (required — e.g. https://sourcegraph.com) plus an optional `SRC_ACCESS_TOKEN` for private instances. The server runs locally over SSE / Streamable-HTTP (default ports 8000/8080) and is installed from source with UV (`uv sync && uv run python -m src.main`), pip (`pip install -e .`), or a bundled Dockerfile; clients like Cursor connect by pointing `.cursor/mcp.json` at the local `http://localhost:8080/sourcegraph/mcp/` URL. It's ideal for agents that need to find and understand code patterns across many repositories rather than a single local checkout.
