OpenUI Cloud MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with OpenUI Cloud MCP or direct API to generate interactive interfaces, manage conversations, create artifacts, and query UI outputs through natural language.

SETUP GUIDE

Connect OpenUI Cloud 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: ["openui"],
  mcp: true,
});
Create a session scoped to OpenUI Cloud 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: "Generate an interactive SaaS pricing dashboard UI artifact with monthly and annual plan toggles",
  stopWhen: stepCountIs(10),
});

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

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

Run OpenUI Cloud tools with your agent

typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Generate an interactive SaaS pricing dashboard UI artifact with monthly and annual plan toggles" }],
});

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 OpenUI Cloud tool calls through the session, and print the final answer

Why Use Composio?

AI Native OpenUI Cloud Integration

  • Supports both OpenUI Cloud MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable UI, conversation, and artifact actions
  • Rich coverage for generating interfaces, reading conversations, and working with OpenUI Cloud artifacts

Managed Auth

  • Secure API key handling without hard-coding OpenUI Cloud credentials in your agent code
  • Central place to manage, scope, and revoke OpenUI Cloud access
  • Per user and per environment credentials so local, staging, and production stay clean

Agent Optimized Design

  • Tools are tuned for language models, so agents can generate OpenUI Cloud interfaces with fewer brittle prompts
  • Clear execution logs show what UI, artifact, or conversation action ran, when, and on whose behalf

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access OpenUI Cloud
  • Scoped, least privilege access to OpenUI Cloud resources
  • Full audit trail of agent actions to support review and compliance
FAQ

Frequently asked questions

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

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

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

With Composio, you connect OpenUI Cloud 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.
