Jina.ai Grounding MCP Server
This server integrates Jina.ai Grounding API to ground LLM responses with real-time web content. You can:
Fact-check statements using real-time web search results
Verify content factuality with precise relevance scoring
Restrict searches to specific URLs when needed
Bypass cache for fresh search results
Configure parameters like format and token budget through the
ground_contentAPIOptimize responses with clean formats specifically designed for LLMs
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Jina.ai Grounding MCP Server ground the latest developments in quantum computing with current web sources"
That's it! The server will respond to your query, and you can continue using it as needed.

Available Tools
1 toolground_statementA
Ground a statement using real-time web search results to check factuality. When providing URLs via the references parameter, ensure they are publicly accessible and contain relevant information about the statement. If the URLs do not contain the necessary information, try removing the URL restrictions to search the entire web.
Inputs: statement (required), references, no_cache.

Scored across 1 tool
With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'ground_statement' has a clearly defined and distinct purpose: fact-checking statements using web search.
Since there is only one tool, naming consistency is inherently perfect. The tool name 'ground_statement' follows a clear verb_noun pattern, which would be consistent if more tools were added.
A single tool is too few for a server that appears to handle grounding/verification tasks, as it suggests an incomplete or minimal surface. Typically, such a domain might include tools for different grounding methods, batch processing, or related operations.
The server is severely incomplete for its apparent grounding/fact-checking domain. It lacks essential operations like grounding multiple statements, verifying against specific sources, or handling different input formats, which limits agent workflows.
