Tools allow your voice agents to interact with external systems, fetch data, and perform actions beyond conversation. By connecting your agents to APIs and services, you can create powerful workflows that integrate with your existing business systems—from looking up customer data in your CRM to checking appointment availability and processing orders.

​
Getting Started

Choose your implementation path based on how you want to work with tools:

Configure in Dashboard

Create and manage tools using the web interface. Perfect for configuring tools visually, testing API integrations, and setting up reusable templates.

Integrate via API

Build tools programmatically using the Hamsa API. Ideal for automated deployments, infrastructure as code, and dynamic tool generation.

​
What are Tools?

Two Tool Types Available:
  • API Request: Make HTTP requests to external APIs
  • MCP Server: Connect to Model Context Protocol servers for standardized AI integrations
Tool Templates vs Instances
  • Template: Reusable tool definition stored in your tool library
  • Instance: Reference to a template with optional agent-specific overrides
  • Use the same tool across multiple agents with different configurations
Tool Versioning
  • Tools use semantic versioning to manage updates
  • Version changes when breaking modifications occur
  • Sync agents to latest versions or pin to specific versions
Web Tools
  • Special execution mode for browser-based deployments
  • Render as interactive forms in web chat interfaces
  • Execute client-side when using the Hamsa SDK
