MCP server for JinaAI grounding
Mcp jinaai grounding mcp server lets Claude, Cursor and other MCP clients work with MCP Jinaai Grounding directly. MCP server for JinaAI grounding.
The functionality of this tool is now available in mcp-omnisearch, which combines multiple MCP tools in one unified package.
Once connected, the assistant can call these 3 tools directly:
ground_content — Ground LLM responses with real-time web content using Jina.ai GroundingSetup — The Setup tool exposed by this serverPublishing — The Publishing tool exposed by this serverThe server is distributed via npm as mcp-jinaai-grounding, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply one environment variable: JINAAI_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.
Search and scraping servers exist to fix the single most common failure of any assistant: answering from stale training data instead of what is on the web today. MCP Jinaai Grounding sits in that group, and the shape of its toolset — ground_content, Setup, Publishing — tells you what it is really for. Worth comparing against the other search web scraping servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
