The official HOL Standards SDK for TypeScript, providing reference implementations of Hashgraph Consensus Service (HCS) standards for file storage, topic registries, agent identity, and agent communication on Hedera. It includes a Registry Broker client for searching, registering, and verifying AI agents, MCP servers, and skills.
Use cases
- build AI agents that communicate over Hedera Consensus Service
- register and discover AI agents in a public agent registry
- store and retrieve files on-chain with HCS-1
- create verifiable agent identities with UAID
- verify skill ownership via DNS TXT domain proof
- build dynamic on-chain inscriptions (Hashinals)
- connect agents to MCP servers and registries
When to choose
- you are building agents or dapps on Hedera that must follow HCS standards
- you need agent discovery, identity, or registry integration via the HOL Registry Broker
- you want TypeScript tooling for inscriptions, topic registries, or agent profiles on Hedera
When to avoid
- you need a general-purpose Hedera client without HCS standards support (use @hashgraph/sdk directly)
- your project has nothing to do with Hedera or agent registries
- you need a minimal-footprint dependency and only want registry search (use the standalone @hol-org/rb-client instead)
