SETUP GUIDE

Connect Enginemailer MCP Tool with your Agent

Install Composio

typescript

npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai

Install the Composio SDK and your agent framework

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: ["enginemailer"],
  mcp: true,
});

Create a session scoped to Enginemailer and read its MCP URL and headers

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: "Create a new campaign for the spring sale newsletter and schedule it for next Monday at 10am.",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();

Pass the session's MCP URL and headers to your agent and run a Enginemailer request

SETUP GUIDE

Connect Enginemailer API Tool with your Agent

Install Composio

typescript

npm install @composio/core @composio/openai openai

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK

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: ["enginemailer"] });
const tools = await session.tools();

Initialize Composio with the OpenAI Responses provider and create a session scoped to Enginemailer

Run Enginemailer tools with your agent

typescript

let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Create a new campaign for the spring sale newsletter and schedule it for next Monday at 10am." }],
});

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

FAQ

Frequently asked questions

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

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

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

With Composio, you connect Enginemailer 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.
