SETUP GUIDE
Connect Omnisend MCP Tool with your Agent
1
Install Composio
typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openaiInstall 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: ["omnisend"],
mcp: true,
});Create a session scoped to Omnisend 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: "Send promotional SMS to all new subscribers registered this week",
stopWhen: stepCountIs(10),
});
console.log(text);
await client.close();Pass the session's MCP URL and headers to your agent and run a Omnisend request

Connect Omnisend API Tool with your Agent
1
Install Composio
typescript
npm install @composio/core @composio/openai openaiInstall the Composio SDK, the OpenAI provider, and the OpenAI SDK

model: "gpt-5.6-sol",
tools,
previous_response_id: response.id,

FAQ
Frequently asked questions
Omnisend requires connections to go through your own OAuth app. You register it once with Omnisend, add its client ID and secret in the Composio dashboard, and from then on everyone connects by signing in to Omnisend as usual. Composio handles the rest of the flow and the token refresh.
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 Omnisend 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.
When you connect a Omnisend account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Omnisend 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.
Exactly the ones Omnisend lists on its consent screen when you connect. Review that screen before approving. If you connect a work account, your Omnisend administrator may need to approve the app first, and you can revoke the access inside Omnisend whenever you want.
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 Omnisend 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.
Composio refreshes Omnisend tokens automatically, so day to day you do nothing. If you revoke access inside Omnisend, or Omnisend invalidates the session, the connection shows as expired in Composio and the agent stops acting on that account until you reconnect it, which is a single sign-in.
Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal Omnisend use. Paid plans add higher limits and team features. Your Omnisend 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 Omnisend accounts).
With Composio, you connect Omnisend 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.
