JManus is a Java implementation of Manus, currently used in many applications within Alibaba Group. It is primarily used for handling exploratory tasks that require a certain degree of determinism, such as quickly finding data from massive datasets and converting it into a single row in a database, or analyzing logs and issuing alerts.

JManus also provides HTTP service invocation capabilities, making it suitable for integration into existing projects. For details, please refer to the developer quick start guide.

A pure Java multi-agent collaboration implementation that provides a complete set of HTTP call interfaces, suitable for secondary integration by Java developers.

Allows you to precisely control every execution detail, providing extremely high execution determinism and completing complex repetitive processes and functions. For specific examples, see JManus Use Cases - FuncAgent Use Case

Natively supports the Model Context Protocol (MCP) for seamless integration with external services and tools.

cd JManus

💡 Get your DashScope API Key: Visit Alibaba Cloud Console to obtain your free API key.

Using other providers? Update the configuration in src/main/resources/application.yml to use your preferred AI model platform.

JManus supports both H2 (default)、MySQL and PostgreSQL databases.

How To Use MySQL/PostgreSQL

1. Configure Database Connection: Update the database configuration and JPA database-platform in the application-mysql.yml/application-postgres.yml under 'src/main/resources/':

   spring:
     datasource:
       url: your_url
       username: your_username
       password: your_password
     jpa:
       database-platform: org.hibernate.dialect.MySQLDialect/PostgreSQLDialect

2. Activate MySQL/PostgreSQL Profile: Update configuration in src/main/resources/application.yml:

   spring:
     ...
     profiles:
       active: mysql/postgres

💡 Note: The application will automatically create required tables on first startup using JPA's ddl-auto: update configuration.

For Unix-like systems (macOS, Linux):

../mvnw spring-boot:run

For Windows systems:

../mvnw.cmd spring-boot:run
