Solana AI Registries

What is Solana AI Registries?

Solana AI Registries is a comprehensive on-chain registry system for autonomous AI agents and Model Context Protocol (MCP) servers, built on the Solana blockchain. It provides decentralized infrastructure for discovering, verifying, and interacting with AI agents and MCP-compliant tools.

How to use Solana AI Registries?

Configure Solana CLI for devnet, then query program accounts using solana program show or JavaScript’s getProgramAccounts. Register agents or MCP servers by constructing the corresponding on-chain instructions in Rust or via connected clients. The registries are live on Solana Devnet with dedicated program addresses.

Key features of Solana AI Registries

• 100% protocol compliance with A2A, AEA, and MCP specifications
• Hybrid data model with on-chain essentials and off-chain verified metadata
• Comprehensive input validation and security-focused sanitization
• Event emission for powerful off-chain indexing
• Owner-based access control with cryptographic verification
• 100% test coverage with edge-case testing

Use cases of Solana AI Registries

• Register and discover autonomous AI agents for decentralized applications
• Find and verify MCP servers offering tools, resources, and prompts
• Build event-driven off-chain indexes for real-time agent/server discovery
• Securely manage agent metadata and status with on-chain ownership

FAQ from Solana AI Registries

What registries are included?

Two interconnected registries: an Agent Registry for autonomous AI agents and an MCP Server Registry for Model Context Protocol–compliant servers.

How do I register an agent or MCP server?

Use the provided Rust instructions (e.g., RegisterAgent, RegisterMcpServer) with valid input, then submit the transaction to the appropriate Solana program on devnet.

How do I query the registries?

Perform direct PDA lookups via Solana CLI (solana program show) or JavaScript (getProgramAccounts). Alternatively, listen for on-chain events for off-chain indexing.

What are the costs for using the registries?

Registration costs ~0.02 SOL (rent-exemption + fees), updates ~0.001 SOL, and queries are free.

Where are the registries deployed?

They are live on Solana Devnet. Agent Registry program ID: BruRLHGfNaf6C5HKUqFu6md5ePJNELafm1vZdhctPkpr; MCP Server Registry program ID: BCBVehUHR3yhbDbvhV3QHS3s27k3LTbpX5CrXQ2sR2SR.
