MyEmailVerifier MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with MyEmailVerifier MCP or direct API to verify email deliverability, detect disposable addresses, flag role-based accounts, and check catch-all or greylisted status through natural language.

SETUP GUIDE

Connect MyEmailVerifier 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: ["myemailverifier"],
  mcp: true,
});
Create a session scoped to MyEmailVerifier 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: "Verify lead@example.com with MyEmailVerifier and report deliverability, disposable, role-based, catch-all, and greylisted status",
  stopWhen: stepCountIs(10),
});

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

Connect MyEmailVerifier 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: ["myemailverifier"] });
const tools = await session.tools();
Initialize Composio with the OpenAI Responses provider and create a session scoped to MyEmailVerifier
3

Run MyEmailVerifier tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Verify lead@example.com with MyEmailVerifier and report deliverability, disposable, role-based, catch-all, and greylisted status" }],
});

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 MyEmailVerifier tool calls through the session, and print the final answer

FAQ

Frequently asked questions

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

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

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

With Composio, you connect MyEmailVerifier 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.
