TOOLS

Supported Tools

Every Sequenzy action and event your agent gets out of the box.

Create Tag

Create a reusable subscriber tag definition; Sequenzy normalizes its name to lowercase and replaces spaces with hyphens.

Delete Tag

Permanently delete a non-system tag definition and remove it from every subscriber.

Get Email Metrics

Return workspace-wide email delivery and engagement totals and rates for a sliding window or custom range, optionally filtered by email type or mailbox provider.

Get Subscriber

Retrieve one subscriber by email with list memberships, sequence enrollments, notes, engagement totals, and recent activity.

List Campaigns

Discover campaigns in the connected workspace, optionally filtered by delivery status or label, without scheduling or sending them.

List Sequences

Discover automation sequences and inspect whether they accept new enrollments or process existing ones, without activating or enrolling anyone.

List Subscriber Lists

Return the reusable subscriber lists available for audience filtering and membership workflows.

List Subscribers

Search and filter subscribers in the connected workspace, returning one stable cursor page for audience review or export.

List Tags

Return reusable subscriber tag definitions, including which tags are protected system tags.

List Templates

Discover reusable email templates and campaign-backed email bodies by label, returning one page with localization metadata.

SETUP GUIDE

Connect Sequenzy 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: ["sequenzy"],
  mcp: true,
});
Create a session scoped to Sequenzy 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: "List Sequenzy subscribers added this week and summarize their status",
  stopWhen: stepCountIs(10),
});

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

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

Run Sequenzy tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "List Sequenzy subscribers added this week and summarize their 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 Sequenzy tool calls through the session, and print the final answer

Why Use Composio?

AI Native Sequenzy Integration

Managed Auth

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

Agent Optimized Design

  • Tools are tuned for AI agents, so Sequenzy actions like listing subscribers or checking campaign analytics are easier for models to call correctly
  • 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 Sequenzy
  • Scoped, least privilege access to Sequenzy resources like campaigns, contacts, and analytics
  • Full audit trail of agent actions to support review and compliance
FAQ

Frequently asked questions

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

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

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

With Composio, you connect Sequenzy 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.
