SETUP GUIDE

Connect OPNForm MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
Install the Composio SDK for Python or TypeScript
2

Initialize Client and Create Tool Router Session

typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
// Create a Tool Router session
const session = await composio.create('your-user-id');
// Optionally create an auth config and link your OPNForm API key (OPNForm uses API_KEY)
const authConfig = await composio.auth_configs.create({ toolkit: 'opnform', auth_type: 'api_key', name: 'opnform-api-key' });
const connected = await composio.connected_accounts.link({ auth_config_id: authConfig.id, credentials: { api_key: 'YOUR_OPNFORM_API_KEY' } });
// You can also explicitly create or inspect an MCP entry
const mcp = await composio.mcp.create({ sessionId: session.id, toolkit: 'opnform' });
console.log(`Tool Router session created: ${session.mcp.url}`);
Import and initialize the Composio client, then create a Tool Router session for OPNForm
3

Connect to AI Agent

typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: "List the 10 most recent submissions for the 'Contact Us' form"
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
Use the MCP server with your AI agent (Anthropic Claude or Mastra)

FAQ

Frequently asked questions

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

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

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

With Composio, you connect OPNForm 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.
