What Merlin Agent Builder does
Merlin is the product you use to compose AI agents. The builder is visual: drop in knowledge sources, choose tools, configure reasoning patterns, add guardrails. You can reach for code anywhere you want finer control.
The output is a production-ready agent — deployed into Slack, Teams, the web, or as an API — that can take real actions in your systems.
What makes it different
Most agent-builder platforms are really chatbot-builders. They retrieve information and respond in text. Merlin was designed for action-first agents.
- Action-first — agents connect directly to 700+ connectors as governed tools. They don’t just answer questions; they reset passwords, refund orders, provision accounts, update tickets.
- Composable agent hub — sub-agents, smart data sources, tool libraries as reusable building blocks. Life360’s composable agent story is the flagship example — new agents take weeks, not months, because each reuses components the prior ones built.
- Guardrails + audit everywhere — every tool call logged, every action traceable, per-user RBAC on sensitive operations. The enterprise governance Merlin inherits from the platform.
- Multi-channel — same agent, multiple surfaces (Slack, Teams, web, API).
