SETUP GUIDE

Connect ApexVerify MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
Install the Composio SDK and your agent framework
2

Create a session with MCP enabled

typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["apexverify"],
  mcp: true,
});
Create a session scoped to ApexVerify and read its MCP URL and headers
3

Connect your agent to the MCP server

typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Validate the email jane.doe@example.com and normalize the phone number +1 415 555 0198",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
Pass the session's MCP URL and headers to your agent and run a ApexVerify request
SETUP GUIDE

Connect ApexVerify API Tool with your Agent

1

Install Composio

typescript
npm install @composio/core @composio/openai openai
Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
2

Create a Composio session

typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["apexverify"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to ApexVerify
3

Run ApexVerify tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Validate the email jane.doe@example.com and normalize the phone number +1 415 555 0198" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
Send a request, execute the ApexVerify tool calls through the session, and print the final answer

Why Use Composio?

AI Native ApexVerify Integration

  • Supports both ApexVerify MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable email and phone validation
  • Practical coverage for checking individual contacts, normalizing phone numbers, and running batch verification workflows

  • Secure API key handling without hard-coding credentials in your agent code
  • Central place to manage, scope, and revoke ApexVerify access
  • Per user and per environment credentials so test and production data stay separate

Agent Optimized Design

  • Tools are shaped for AI agents, so they can choose the right ApexVerify action with fewer mistakes
  • Clear inputs and outputs make it easier to flag invalid emails, malformed numbers, and risky contact records
  • Comprehensive execution logs so you always know what ran, when, and on whose behalf

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access ApexVerify

FAQ

Frequently asked questions

Yes, ApexVerify 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 ApexVerify 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 ApexVerify account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the ApexVerify actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside ApexVerify at any time.

When you connect a ApexVerify account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in ApexVerify 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 ApexVerify. If ApexVerify 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 ApexVerify 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 ApexVerify 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 ApexVerify rejects the old key. Create a new key in ApexVerify and reconnect the account from the Composio dashboard or by asking your agent to reconnect ApexVerify. Nothing else changes.

Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal ApexVerify use. Paid plans add higher limits and team features. Your ApexVerify 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 ApexVerify accounts).

With Composio, you connect ApexVerify 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.
