AI Native Vapi Integration
- Supports both Vapi MCP and direct API based integrations
- Structured, LLM-friendly schemas for reliable tool execution
- Rich coverage for reading, writing, and querying your Vapi data
Vapi MCP server for AI agents and assistants
Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Vapi MCP or direct API to create voice agents, manage conversations, deploy workflows, and analyze call interactions through natural language.
Api Key
Vapi is a voice AI platform for building, testing, and deploying conversational voice agents. It provides real-time responses and seamless integration for voice-driven applications.

SETUP GUIDE
Connect Vapi MCP Tool with your Agent
1
Install Composio
typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcpInstall the Composio SDK for Python or TypeScript
2
Initialize Client and Create Tool Router Session
typescript
import { Composio } from '@composio/core';
const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);Import and initialize the Composio client, then create a Tool Router session for Vapi
3
Connect to AI Agent
typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';
const client = await createMCPClient({
transport: {
type: 'http',
url: session.mcp.url,
headers: {
'x-api-key': 'your-composio-api-key',
},
},
});
const tools = await client.tools();
const { text } = await generateText({
model: openai('gpt-4o'),
tools,
messages: [{
role: 'user',
content: 'Start a new voice agent session with the welcome script.'
}],
maxSteps: 5,
});
console.log(`Agent: ${text}`);Use the MCP server with your AI agent (Anthropic Claude or Mastra)

Execute Vapi Tools via Tool Router with Your Agent
typescript
const tools = session.tools;
const response = await openai.responses.create({
model: 'gpt-4.1',
tools: tools,
input: [{
role: 'user',
content: 'Start a new voice agent session with the welcome script.'
}],
});
const result = await composio.provider.handleToolCalls(
'your-user-id',
response.output
);
console.log(result);Get tools from Tool Router session and execute Vapi actions with your Agent

FAQ
Frequently asked questions
Yes, Vapi requires you to configure your own API key. Once set up, Composio handles secure credential storage and API request handling for you.
Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.
Yes. Composio is SOC 2 Type II compliant and is built to keep your Vapi connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.
Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.
Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.
Create the key in your Vapi account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the Vapi actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside Vapi at any time.
When you connect a Vapi account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Vapi as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.
Whatever the credentials you connect allow inside Vapi. If Vapi lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside Vapi at any time.
Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each Vapi connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.
The connection stops working the moment Vapi rejects the old key. Create a new key in Vapi and reconnect the account from the Composio dashboard or by asking your agent to reconnect Vapi. Nothing else changes.
Composio's free plan includes 100,000 tool calls per month with no credit card, which covers most personal Vapi use. Paid plans add higher limits and team features. Your Vapi plan and its API limits still apply as usual.
Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple Vapi accounts).
With Composio, you connect Vapi once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
