Agent Registry
Overview
The Agent Registry is the central database where all metadata for every agent in the AgNet ecosystem is stored. This critical layer of the ecosystem plays a key role in agent identification, capability management, and lifecycle monitoring.
Architecture of the Agent Registry
The architecture of the Agent Registry is designed for efficient handling and accessibility of agent metadata in the AI Agent Network (AgNet). Key components include:
Metadata Repository
Centralized Storage: Stores metadata for every agent, ensuring consistency and reliability.
Key Information:
UUID
Agent capabilities and functions
Current status and availability
Communication endpoints (URLs and APIs)
Dynamic Updates
Real-Time Changes: Reflects updates to agent metadata instantly.
Lifecycle Tracking: Tracks changes as agents are launched, updated, or retired, ensuring the network remains current.
Key Functionalities of the Registry
The Agent Registry supports several pivotal functions to maintain the integrity and efficiency of AgNet:
Agent Discovery
Acts as the backend for the Agent Name Server (ANS).
Resolves agent queries and connects users to the right agents using metadata.
Capability Matching
Analyzes registered capabilities of agents.
Matches incoming queries or tasks to the most suitable agents for optimal resource allocation and task execution.
Agent Lifecycle Management
Tracks the lifecycle of agents from creation and deployment to modification and decommissioning.
Ensures metadata consistency across the network.
Integration with the Agent Name Server (ANS)
Serves as a data source for ANS.
Provides UUIDs and endpoints to ANS for executing tasks.
Advantages of the Agent Registry
Centralized Database: Serves as the foundation for managing agents.
Scalability: Supports real-time updates and lifecycle management, making the network adaptable.
Efficiency: Ensures consistent metadata handling, improving workflow and reducing errors.
Agent Name Server (ANS)
Overview
The Agent Name Server (ANS) is the discovery engine within the AgNet architecture. It acts as an intermediary, mapping user intents to agents and simplifying the discovery process for seamless communication between Client-Agents and Server-Agents.
Core Responsibilities
Intent Resolution: Translates high-level intents from Client-Agents into actionable endpoints by querying the Agent Registry.
Caching: Maintains a local cache of frequently used agent information to minimize delays.
Fallback Mechanism: Queries the Agent Registry to refresh or retrieve required data when cache misses occur.
Query Flow
A Client-Agent sends a query with intent and entities to ANS.
ANS checks its cache for the Agent UUID and endpoint.
If data is unavailable in the cache, ANS queries the Agent Registry.
ANS retrieves the required UUID and endpoint and sends it back to the Client-Agent.
Integration with ATTP Protocol
Secure Communication: Uses the ATTP protocol to enable secure exchanges between agents.
ATTP Features:
Encryption
Authentication
Versioning headers
Security Features
Authentication: Verifies Client-Agent identity using authentication tokens in ATTP headers.
Access Control: Restricts searches and data retrieval to authorized users.
Data Integrity: Ensures data remains unaltered during transmission through cryptographic methods.
Advantages of ANS
Simplified Discovery: Abstracts direct interactions with the registry, making discovery user-friendly for Client-Agents.
Performance Optimization: Caching and resolution mechanisms enhance system efficiency.
Fault Tolerance: Robust fallback mechanisms and error handling ensure reliable operation under various conditions.
