MCP server for deep web search using @just-every/search
MCP server for deep web search using @just-every/search. Exposed over MCP by the mcp deep search mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
MCP server for deep web search using @just-every/search. Search across multiple providers including Google, Bing, Brave, DuckDuckGo, Perplexity, and more.
The server ships on npm as @just-every/mcp-deep-search, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Everything the assistant can do here goes through one of these:
Brave — brave.com/search/apiAnthropic — console.anthropic.comOpenAI — platform.openai.comGoogle — makersuite.google.comOpenRouter — openrouter.aixAI — x.aideep_search — The deep_search tool exposed by this servercomprehensive_research — Perform comprehensive research using AI agents that intelligently select and query multiple search enginesYou will need 7 environment variables: ENV_FILE, BRAVE_API_KEY, ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, OPENROUTER_API_KEY, XAI_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Deep Search's toolset — Brave, Anthropic, OpenAI and 5 more — is a fair guide to whether it matches your workflow. It is maintained by just-every; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Search built for AI, not humans — semantic web search that returns model-ready content, plus code context.
Answers, not links — delegate questions to Perplexity's search-grounded models and get cited responses back.
Give your assistant a voice — text-to-speech, voice cloning and audio tools from the ElevenLabs API.
Give your assistant a real code sandbox — isolated cloud VMs for actually running the code it writes.
The ML hub in your context window — search models, datasets, papers and run Spaces from the official server.
Thousands of open models on tap — run image, video and audio generation through Replicate's hosted API.
