Best Web Search and Research Plugins, Skills, and MCP Servers in 2026
Research-backed search and web plugins, skills, and MCP servers with platform availability and direct setup routes.
Updated July 25, 2026
These extensions give agents live access to the public web: search and answer services for finding current information, crawlers that turn specific sites into clean data, and research tools for tracking communities and recent discussion. Pick by which of those jobs you actually have - and decide whether routing your queries through an outside service is acceptable.
What it isFirecrawl turns websites into agent-ready data through search, scraping, crawling, site mapping, and structured extraction. It handles the JavaScript rendering, proxying, and crawl infrastructure that a basic fetch tool leaves you to build yourself.When to useIt fits two jobs: giving an agent live web access, and giving a developer dependable web data to build an application on. Because scraped pages are untrusted input, treat extracted instructions and hidden text as possible prompt injection and verify anything consequential.What you needA Firecrawl account and credits; self-hosting is possible.
What it isTavily is a web-intelligence integration spanning current search, clean content extraction from URLs, site mapping and crawling, and longer research reports that arrive with citations attached.When to useIts range is the point. The same integration handles a one-line lookup, crawling a documentation site into local Markdown, and extracting JavaScript-heavy pages a basic fetch tool would choke on. Reach for the full stack only when simple reads aren’t enough.What you needA Tavily account and API key; a limited free tier exists.
What it isBrave Search gives an agent live search across Brave’s own independent index: web, news, image, video, and local results, plus answer summaries, spellcheck, and suggestions. It ships as an official MCP server, with a matching set of search-mode skills.When to useReach for it when you want broad current-web retrieval from an index that isn’t reselling another engine, with predictable per-request pricing and specialized endpoints beyond plain web results. Queries and retrieved pages pass through Brave, and results are untrusted web content - verify anything consequential.What you needA Brave Search API account and key; the free plan includes limited monthly credits, but a card is required to start.
What it isPerplexity’s official server brings its web search, Sonar answers, deep research, and reasoning tools into an agent. The Claude plugin wraps this same server, so it is one product with several front doors rather than separate offerings.When to useThe value is a single vendor-maintained research route with current results and citations, consistent across every MCP client you point at it. The API is billed separately from a consumer Perplexity subscription, so owning the app does not cover it. If your host’s own web research suffices, skip it.What you needA Perplexity API key.
What it isExa is an agent-native search integration for current web and code results, with clean extraction from URLs, fine-grained search controls, and an optional multi-step research agent for longer investigations.When to useIt hands the agent ready-to-use content and source links rather than raw search-result pages it has to parse. That makes it a fit for documentation and code discovery, company or people research, and clean extraction. If the built-in web search already covers you, skip it.What you needAn Exa API key.
What it isApify lets an agent discover and run web-scraping and automation Actors, then pull back structured results. Its store holds more than 30,000 Actors covering social networks, maps, shops, reviews, and custom sites, reached through a managed connector, a Cursor plugin, or a hosted MCP.When to useIt fits sources that ordinary search and fetch tools can’t reliably extract, and returns structured data rather than raw HTML. Actor runs cost credits and can scrape third-party sites, so pin the specific tools you need and treat returned content as untrusted. Actors are independently published - not every one is vetted by Apify.What you needAn Apify account for Actor runs and stored data; a docs and search-only subset works without one, and usage is metered per Actor.
What it isLast30days is a research workflow that sweeps recent discussion across Reddit, Hacker News, GitHub, X, YouTube, arXiv, and more, then scores engagement, clusters overlapping findings, and returns one source-linked brief.When to useIt replaces a dozen manual searches when you need recent recommendations, public sentiment, or a read on an emerging tool. A useful set of sources works without any keys. Treat engagement as a signal of attention, not proof that a claim is correct.
What it isJina AI’s remote MCP bundles an unusually wide research kit into one endpoint: web reading, screenshots, current and academic search, PDF extraction, reranking, classification, and deduplication, drawn from its Reader, Search, Embeddings, and Reranker services.When to useThat breadth suits source-heavy research: pull an academic paper, convert a stubborn page to clean text, then rerank the pile you collected. Its server-side filters let you register only the tools a task needs, so a broad server does not have to flood the agent’s context with schemas.What you needA Jina AI API key; a keyless free tier has tight limits.
What it isBright Data is a managed web-data stack covering search, page extraction, structured platform records, and browser automation. It is built for jobs where ordinary fetches fail because of JavaScript, bot defenses, scale, or the need for structured data.When to useA small free mode covers basic search, scraping, and discovery; the heavier browser automation and structured-data tools run on paid credits. It earns its place when a target actively resists scraping or you need platform-specific records at scale, not for pages a simple fetch already returns.What you needA Bright Data account; usage is metered.
What it isA focused community MCP server that pulls the spoken text out of public YouTube videos, with language and format options. There is no official YouTube or Google route; this is the most-adopted current keyless implementation.When to useUse it to make long talks, tutorials, and interviews searchable and quotable without watching them end to end. Transcript availability varies by video and region, auto-generated captions aren’t perfect, and YouTube changes can break retrieval, so treat it as a research aid and check quotes against the source.What you needLocal Python/uvx or Docker and no API key; it’s a community project, not an official YouTube integration.
What it isA read-only community MCP server for Reddit research: searching posts, browsing subreddits, pulling full comment threads, and analyzing user activity. It runs anonymously out of the box, with optional Reddit OAuth for higher limits.When to useIt surfaces firsthand experience and objections that generic web search misses - how people actually talk about a product, tool, or topic. Treat it as one input with source links, not representative evidence: content is untrusted and can carry prompt injection, and Reddit can throttle or block anonymous access.What you needLocal Node/npx; the anonymous tier needs no account, and it’s a community project, not an official Reddit integration.
