Merlin Agent Builder

What it does

Merlin Agent Builder is Tray.ai's no-code environment for creating AI agents from knowledge sources, tools, and reasoning instructions. Agents act in company systems rather than only answering questions, using Tray's library of more than 700 app connections. Smart Data Sources ingest, chunk, and embed content automatically so agents work from fresh context.

Teams can build multi-agent setups in which a master agent coordinates sub-agents, each with its own tools and context. The product page shows example agents for CRM, customer support, finance, ITSM, HR, and sales pipeline work. Every tool call is logged, access is controlled per user, and approval workflows can gate sensitive actions. The same agent can be shipped to Slack, Microsoft Teams, a chatbot, or an API.

It suits enterprise automation, IT, and business teams that need agents to act across several systems under governance. The visual builder covers most patterns, and custom code steps are available where needed. Access starts with a demo request or a free trial. Agent-specific pricing is not published, so buyers should confirm cost with Tray.
