# Building with AI

## Building with AI

Accelerate development with AI coding agents that understand Twilio's APIs, or deploy AI-powered communication products that handle conversations at scale.

[Connect your AI agent](/docs/ai/mcp)

## Tutorial

```json !sample
{
  "tool": "twilio__search",
  "query": "How do I send an SMS?",
  "result": {
    "endpoint": "POST /2010-04-01/Accounts/{AccountSid}/Messages.json",
    "parameters": {
      "From": "Your Twilio phone number",
      "To": "Recipient phone number",
      "Body": "Message content"
    },
    "authentication": "Basic Auth with Account SID and Auth Token"
  }
}
```

1. Install the Twilio MCP server in your AI coding environment (Claude Code or Cursor).
2. Your AI agent gains semantic search access to 1,500+ Twilio API endpoints across 30+ products.
3. Ask natural language questions and receive exact parameter schemas, authentication details, and code examples.

Tutorial code output: "Your AI agent understands Twilio's entire API surface"

## What do you want to build

### Connect AI coding agents to Twilio API documentation

Give your AI coding environment semantic search access to 1,500+ Twilio API endpoints with the MCP server. Install Twilio Skills for guided product knowledge and best practices.

* [Install MCP server](/docs/ai/mcp)
* [Install Twilio Skills](/docs/ai/skills)

### Build with conversational AI products

Connect LLM applications to Twilio services with Twilio Agent Connect (TAC). Integrate AI agents with Voice, Messaging, Conversation Memory, and Conversation Orchestrator using a unified SDK.

* [Get started with Twilio Agent Connect](/docs/conversations/agent-connect)

### Stream voice AI to phone calls

Connect AI agents directly to Twilio Voice calls with Conversation Relay. Twilio handles speech recognition, text-to-speech, and voice synthesis while you focus on your AI logic.

* [Get started with Conversation Relay](/docs/voice/conversationrelay/onboarding)

### Analyze conversations with GenAI

Use Conversation Intelligence to analyze conversations with AI and extract sentiment, summaries, and custom insights from voice calls and messages. Create custom language operators with natural language prompts to detect upsell opportunities, monitor compliance, or provide agent guidance.

* [Get started with Conversation Intelligence](/docs/conversations/intelligence/quickstart)

### Communicate with and control your agents

Ola provides a communication layer between users and their AI agents. It provides a single surface for communication and control across all agent platforms. Ola has been built on the open [Agent-to-Human (A2H) communication protocol](https://www.twilio.com/en-us/blog/products/introducing-a2h-agent-to-human-communication-protocol).

## MCP Server for AI Coding Agents

Connect your AI coding environment to Twilio's API documentation. The Model Context Protocol (MCP) server gives coding agents semantic search access to 1,500+ endpoints across 30+ Twilio products.

Example MCP server response when searching for SMS APIs:

```json {title="MCP server tool definition"}
{
  "name": "twilio__search",
  "description": "Semantic search across 1,500+ Twilio API endpoints",
  "parameters": {
    "query": "send SMS with media",
    "limit": 5
  }
}
```

### What you can do

* **Explore APIs** — Ask "How do I verify a phone number?" and get exact endpoint details.
* **Generate code** — Your agent writes authenticated Twilio SDK calls.
* **Debug faster** — Search error codes and troubleshooting guides in a conversational manner.
* **Stay current** — Keep up-to-date with the latest API changes.

## Ola — Agent-Native Communication Channel

Ola provides a communication layer between users and their AI agents, providing a single surface for communication and control across all agent platforms.

```json {title="Example A2H authorization request"}
{
  "type": "AUTHORIZE",
  "message_id": "01933e4a-1234-7890-abcd-ef1234567890",
  "agent_id": "did:web:travel-agent.example.com",
  "principal_id": "did:example:alice",
  "params": {
    "action": "book_flight",
    "destination": "SFO",
    "date": "2026-05-15"
  },
  "signature": "<detached JWS>"
}
```

### Communication and control

* **Unified communications channel** — Communicate with all of your agents across Claude, OpenClaw, and more through a single interface.
* **Verified identity** — View cryptographic proof for which agent you're approving actions.

### Permissions and approvals

* **Scoped permissions** — Define what each agent can do, what needs approval, and what gets blocked.
* **Tiered approvals** — Use taps for routine tasks and biometric authentication for high-stakes actions.

### Monitoring and safety

* **Activity feed** — Get a signed, tamper-resistant record of every action an agent took and what you approved.
* **Agent killswitch** — Shut down agents that enter loops or deviate from instructions with one click.

### How it works

When an agent needs to take action on a user's behalf, it sends a structured intent through Ola. Ola evaluates the intent against user permission preferences and either auto-approves, routes to the user for authorization, or blocks—with every approval cryptographically signed.
