SETUP GUIDE

Connect Seven.io 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: ["seven_io"],
  mcp: true,
});
Create a session scoped to Seven.io 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 an SMS to +491701234567 saying \"Your appointment is confirmed for tomorrow at 10 AM\" using Seven.io",
  stopWhen: stepCountIs(10),
});

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

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

Run Seven.io tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Send an SMS to +491701234567 saying \"Your appointment is confirmed for tomorrow at 10 AM\" using Seven.io" }],
});

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 Seven.io tool calls through the session, and print the final answer

Why Use Composio?

AI Native Seven.io Integration

  • Supports both Seven.io MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable SMS, voice, contact, and analytics actions
  • Rich coverage for sending messages, checking delivery status, managing contacts, and querying communication data

Managed Auth

  • Create Seven.io API key auth configs with auth_configs.create() and connect users with connected_accounts.link()
  • Composio stores Seven.io API keys securely, so you don't hard-code credentials in agent prompts or app code
  • Per user and per environment credentials make it simple to test, ship, and revoke access when needed

Agent Optimized Design

  • Tools are tuned using real error and success rates to improve reliability over time
  • Comprehensive execution logs show which Seven.io action ran, when it ran, and on whose behalf
  • Use mcp.create() when you want to expose Seven.io tools over MCP for Claude, Cursor, or other MCP-ready agents

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access Seven.io messaging tools
  • Scoped, least privilege access for SMS, voice, contact, number, and analytics workflows
  • Full audit trail of agent actions to support review, debugging, and compliance
FAQ

Frequently asked questions

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

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

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

With Composio, you connect Seven.io 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.
