概要

What is jcrawl4ai-mcp-server?

jcrawl4ai-mcp-server is a Spring Boot-based MCP server (Java implementation) that interacts with the Crawl4ai API to perform web crawling. It allows users to crawl specified URLs with configurable strategy, maximum depth, and output format, and to retrieve crawl results by task ID.

How to use jcrawl4ai-mcp-server?

Configure the cawl4ai.base-url and cawl4ai.api-token properties in src/main/resources/application.properties. Build with Maven (mvn clean install) and run the resulting JAR (java -jar target/jcrawl4ai-mcp-server-1.0.0.jar). A pre-built JAR is also available for download. The server uses stdio transport as shown in the MCP configuration example.
