Langgraph Deepsearch MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCPサーバーがClaude DesktopなどのMCPホストに接続されると、以下のような自然言語でリサーチを依頼できます：.
Once Langgraph Deepsearch MCP is connected, these are the calls the assistant has available:
GEMINI_API_KEY — Gemini API (必須) - Google AI Studioから取得deep_search — The deep_search tool exposed by this serverquick_search — The quick_search tool exposed by this serverget_search_tools — The get_search_tools tool exposed by this serverYou will need one environment variable: GEMINI_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.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Langgraph Deepsearch MCP's toolset — GEMINI_API_KEY, deep_search, quick_search and 1 more — is a fair guide to whether it matches your workflow. It is maintained by RyotaOzawa0; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
