Agentnexus

AgentNexus is a Java and Spring-based framework for building server-side AI agent applications. It stores agent components such as models, tools, prompts, memory, and retrieval sources in a database, then assembles agents dynamically through APIs. It supports multi-agent planning and delegation, chained workflows, scheduled workflow triggers, persistent conversation memory, and file or Git-repository ingestion into a

Practical overview

When it fits

Use AgentNexus when developing a Java/Spring service that needs configurable agent orchestration, chained or scheduled workflows, or retrieval grounded in files and Git repositories.

Who it is for

  • Java developers building configurable AI agent services with Spring.
  • Teams connecting multiple agents into sequential or delegated tasks.
  • Developers adding file- or repository-based retrieval to an agent application.

Documented uses

  • Configure agents from stored models, tools, prompts, memory, and knowledge sources.
  • Plan complex tasks and delegate work among a dynamically assembled agent team.
  • Chain agents into workflows and trigger workflows on a cron schedule.
  • Ingest uploaded files or Git repositories into PgVector for retrieval-augmented generation.
  • Persist multi-turn conversation context using a conversation ID.
Before you choose

Requirements & limits

The project is documented as open source, and its README states that it uses the MIT License.

  • The documented implementation stack requires Java 17+, Maven 3.6+, MySQL 8.0+, PostgreSQL 15+ with pgvector, and Nacos 2.2.0+.
  • Docker is optional in the README's setup instructions.
  • Developers must provide database configuration and model-provider API keys in Nacos.
  • Java Function beans can be exposed as pluggable tools through Spring AI ToolCallback and associated with agents.
  • The visual workflow designer and observability dashboard appear in the README roadmap as planned features, not current capabilities.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare the AgentNexus service configuration

Set up the documented prerequisites and configuration for building and starting AgentNexus.

Before you start

  • Java 17 or later
  • Maven 3.6 or later
  • MySQL 8.0 or later
  • PostgreSQL 15 or later with the pgvector extension
  • Nacos 2.2.0 or later

Steps

  1. Clone the AgentNexus repository and change into its project directory.

  2. Run the SQL script at sql/schema.sql in MySQL to create the required tables.

  3. Create a YAML configuration in Nacos with Data ID agent-nexus-dev.yml, or a custom name, and Group DEFAULT_GROUP; use resources/application.yml as the template and configure database settings and model-provider API keys.

  4. Build with Maven using the documented package command, then start target/AgentNexus.jar with Java.

Expected outcome

The documented setup path builds and starts the application; its README points to Swagger UI at localhost:8091/swagger-ui.html for API documentation, subject to the configured port.

Guide limitations

  • The guide covers the README's setup path, not independent verification of a successful deployment.
  • A running Nacos service and configured databases are required by the listed setup; Docker is described only as an optional way to start dependency services.
