MCP

Overview

This is a robust remote MCP server developed by Jina AI that exposes numerous tools for web scraping, content extraction, and AI-powered operations. It includes 19 different tools categorized into search, parallel operations, reading, utilities, and reranking functions. The server uses Streamable HTTP transport (MCP spec 2025-03-26) and supports API key authentication for higher rate limits. A unique feature is its ability to filter tools via query parameters before registering them with MCP clients, which helps optimize context window usage for LLMs with limited capacity.

FAQ

How can I limit which tools are registered to save context window space?

Use query parameters on the endpoint URL such as ?exclude_tags=parallel or ?include_tools=read_url,search_web to filter which tools are registered with the MCP client.

Why does Claude Desktop show 'Server disconnected' on Windows?

This is a known bug with spaces in args not being escaped properly. Work around it by setting Authorization:${AUTH_HEADER} in args and AUTH_HEADER='Bearer <key>' in env variables.
