Build integrations that feel natural to conversation

MCP Servers

Custom Tools

Create new capabilities Ferni can use mid-conversation. Webhook-based, MCP, or simple prompt tools.

6 endpoints

Webhooks

Stay informed about what matters. Subscribe to session events, tool calls, and conversation milestones.

7 endpoints

Workflows

Orchestrate multi-step processes. Branching logic, parallel paths, and graceful error handling.

8 endpoints

Activities

Track meaningful moments. Log custom activities and query patterns over time.
