Tool Registry & Marketplace

Tools are what turn an AI agent from a talker into a worker. The Tool Registry manages every capability your agents can use.

Built-in tools

Every organization gets the system tools out of the box:

• Knowledge lookup — answer questions from the knowledge base.
• Transfers — ring a person, a department, another AI agent, or a clocked-in human agent.
• Voicemail — capture a message.
• Send SMS — text the caller a link or details mid-call (consent required, capped per call).
• Touch-tone (DTMF) — navigate phone menus on outbound calls.

Your own HTTP tools

Add a custom tool that calls your API: define its name, description, parameters, and the HTTP request to make. Optional request/response scripts shape the payload, and secrets (API keys) are stored encrypted — per organization, with per-agent overrides. Once added, bind the tool to the agents that should use it; the AI sees the description and calls it when relevant, live on the call.

A classic example: a provider-search tool the agent uses to look up nearby providers while the caller waits.

Marketplace

The marketplace offers ready-made tools you can install into your organization and bind to agents without building anything.

Binding tools to agents

Tools are enabled per-agent, so each agent carries only what its job needs. Pre-call hooks can also run a tool before the agent answers — e.g. a CRM lookup that injects caller context into the prompt (CRM Connectors).

Observability

Every tool invocation is logged on the call record — inputs, outputs, latency, success or failure — so you can audit exactly what your agents did (Calls & Transcripts).
