Jina AI Web Search MCP server

The MCP Server (Jina Reader API) provides web content searching and fetching capabilities through the Jina Reader API. It allows you to read webpage content and perform web searches directly from your applications.

Installation

To use the MCP Server with Jina Reader API, you need to configure it in your application. The server runs as a Java application.

Prerequisites

• Java runtime environment
• Jina API key (obtain from Jina AI)
• The MCP server JAR file

Configuration

Add the MCP server configuration to your application's configuration file:

"mcpServers": {
   "mcp-server-jina-java": {
      "command": "java",
      "args": [
        "-Dspring.ai.mcp.server.stdio=true",
        "-jar",
        "/the path of the jar/mcp-server-jina-java-1.0-SNAPSHOT.jar",
        "jina.api.api-key=Your jina key"
      ]
    }
}

Make sure to:

• Replace /the path of the jar/ with the actual path to the JAR file
• Replace Your jina key with your actual Jina API key

Available Tools

The MCP Server provides two main tools for interacting with web content:

Reading Web Content

The readAndFetchContent tool allows you to retrieve content from a specific URL:

• Required parameter: url (string) - The URL to fetch content from

Web Searching

The searchAndGetSERP tool enables web searching capabilities:

• Required parameter: keyword (string) - The search term to query

Usage Examples

Reading Content from a URL

To fetch content from a specific webpage:

{
  "tool": "readAndFetchContent",
  "parameters": {
    "url": "https://example.com/article"
  }
}

Performing a Web Search

To execute a web search and retrieve search engine results:

{
  "tool": "searchAndGetSERP",
  "parameters": {
    "keyword": "artificial intelligence latest developments"
  }
}

These tools can be integrated into applications that support the Model Context Protocol to enhance them with web content access and search capabilities.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-server-jina-java" '{"command":"java","args":["-Dspring.ai.mcp.server.stdio=true","-jar","/the path of the jar/mcp-server-jina-java-1.0-SNAPSHOT.jar","jina.api.api-key= Your jina key"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcp-server-jina-java": {
            "command": "java",
            "args": [
                "-Dspring.ai.mcp.server.stdio=true",
                "-jar",
                "/the path of the jar/mcp-server-jina-java-1.0-SNAPSHOT.jar",
                "jina.api.api-key= Your jina key"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcp-server-jina-java": {
            "command": "java",
            "args": [
                "-Dspring.ai.mcp.server.stdio=true",
                "-jar",
                "/the path of the jar/mcp-server-jina-java-1.0-SNAPSHOT.jar",
                "jina.api.api-key= Your jina key"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
