Overview

Welcome to the official documentation for Nexus — the central registry for discovering, sharing, and integrating AI agents!

In today’s rapidly evolving AI landscape, intelligent agents are unlocking new capabilities in everything from market analysis to creative text generation. Yet, these specialized agents too often remain locked within isolated silos, unable to interact or leverage each other's strengths. Interoperability—or the lack thereof—remains a major barrier to building robust, multi-agent systems and truly intelligent workflows.

Nexus is an AI Agent Store powered by the A2A Protocol, serving as a unified hub where developers and companies can publish, list, and manage their AI agents. Think of it as the “App Store” for AI agents: a place where each agent is described through an Agent Card, complete with metadata, skills, API endpoints, and Docker images. Users can seamlessly explore, test, and integrate these agents into their own applications—bridging the gap between isolated innovations and collective intelligence.

Whether you’re a developer looking to publish the next breakthrough agent or a user searching for the perfect solution, Nexus provides a transparent, standards-based platform for interoperability and collaboration. Discover, share, and build smarter—together.

What is Nexus?

Nexus is an “App Store” for AI agents, where developers publish their agents and users can discover, access, and integrate them seamlessly.

Why it matters?​

In the rapidly growing AI ecosystem, developers often rebuild similar capabilities for each project. Our platform reduces this duplication by enabling agent reuse and interoperability. Instead of writing new agents from scratch, users can integrate existing, well-documented agents into their workflows.

Benefits include:

  • Time-saving: Quickly integrate agents instead of building from scratch.
  • Interoperability: All agents follow the A2A protocol, making them compatible across applications.
  • Ease of use: Discover agents using intuitive search, filtering by skills, tags, or name.
  • Reusability: Leverage community-published agents for various use cases like NLP, finance, data analysis, or image processing.

Nexus not only increases productivity by reducing redundant work, but also accelerates adoption of state-of-the-art AI, ensuring that every project benefits from the collective progress of the AI community.

Who it's for?​

Developers and Providers​

Publish and showcase AI agents to reach a wider audience with ease. By supplying comprehensive metadata, specifying agent skills, API endpoints and sharing Docker images, developers and companies enable seamless integration and adoption by users. Nexus streamlines discoverability, fosters collaboration, and makes managing agent versions, authentication, and endpoints straightforward. Publishing through Nexus increases the visibility of each agent, connects providers with the AI community, and encourages ongoing innovation.

Users & Teams​

Effortlessly explore, select, and integrate AI agents into any project. Users can browse agents tailored to specific requirements, retrieve detailed Agent Cards, obtain API endpoints, and pull Docker images for local testing or deployment. Integration is straightforward—connect agents to applications via APIs or Python SDKs, with support for both remote and on-premises environments.

Teams can orchestrate multiple agents to build advanced solutions, leveraging the A2A protocol for seamless, reliable agent-to-agent communication and composition. This standardized system empowers innovators to rapidly assemble powerful workflows, eliminate redundant development, and accelerate product delivery—no matter the use case.

Use Cases​

  • Startup adding currency conversion: A startup wants to enhance their app with currency conversion capabilities. Instead of building a new agent, they discover an existing one in Nexus, pull its Docker image for local testing and debugging, and then integrate it directly by connecting to the agent's API endpoints—accelerating time-to-market without writing new code.

  • Developer publishing image classification: A developer publishes an image classification agent to Nexus, sharing the Docker image and full Agent Card metadata. Other teams can effortlessly incorporate this agent into their processing pipelines and combine it with NLP or analytics agents to create powerful multi-agent workflows using the A2A protocol for seamless communication.

  • Enterprise private repositories: Enterprises leverage Nexus to create private agent repositories, enabling teams to securely host and manage internal AI agents. This ensures sensitive data remains protected while benefiting from all Nexus features like discoverability, version control, and interoperability — perfect for building scalable, compliant AI workflows within the organization.

Key Features​

Discoverability: Find the right tool for the job in a central, searchable marketplace of agents. Interoperability: All agents speak the same language, eliminating the need for custom integration code. Rapid Development: Compose complex workflows by chaining multiple agents together. Build sophisticated applications in a fraction of the time. Standardization: A clear and versioned specification for defining agent capabilities and communication. Extensibility: Our provided SDKs (Software Development Kits) make it easy to register your own agents and call others from your preferred programming language.
