## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including OPNForm.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a OPNForm account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate OPNForm with

- [ChatGPT](https://composio.dev/toolkits/opn_form/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/opn_form/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/opn_form/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to OPNForm
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect OPNForm to Atomic Agent

### Connect OPNForm to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in OPNForm. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your OPNForm account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the OPNForm MCP server, and what's possible with it?

The OPNForm MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your OPNForm account. It provides structured and secure access so your agent can perform OPNForm operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `OPN_FORM_CANCEL_WORKSPACE_INVITE` | Cancel Workspace Invite | Cancel and remove a pending workspace invitation before it is accepted. Requires a personal access token with the workspace-users-write ability. |
| `OPN_FORM_CREATE_FORM` | Create Form | Create an OpnForm form in a workspace from a title, ordered field or layout blocks, and optional validated form settings. Optional retention settings permanently delete future submissions after the configured period. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_CREATE_FORM_INTEGRATION` | Create Form Integration | Create a generic webhook or Make integration for an OpnForm form. This registers an external destination for future form submission data; an active integration can begin sending submissions to that destination immediately, while an inactive integration remains configured without delivery. Requires a personal access token with the manage-integrations ability. |
| `OPN_FORM_CREATE_SUBMISSION` | Create Submission | Submit answers to a public OpnForm form. A completed submission may immediately send its data to active webhook or Make integrations; optionally save a partial submission with completion and campaign-attribution metadata. |
| `OPN_FORM_CREATE_WORKSPACE` | Create Workspace | Create an OpnForm workspace. Account workspace limits may reject creation even when the personal access token has write access. Requires a personal access token with the workspaces-write ability. |
| `OPN_FORM_DELETE_FORM` | Delete Form | Permanently delete a form and all of its submissions by numeric ID. This irreversible operation cannot be undone. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_DELETE_FORM_INTEGRATION` | Delete Form Integration | Permanently remove a webhook integration from a form and stop its future deliveries. This operation cannot be undone. Requires a personal access token with the manage-integrations ability. |
| `OPN_FORM_DELETE_SUBMISSION` | Delete Submission | Permanently delete one submission from a form using both numeric IDs. This irreversible operation cannot be undone. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_DELETE_SUBMISSIONS` | Delete Submissions | Permanently delete 1-25 submissions from one form through sequential provider requests. This operation is irreversible and not atomic: confirmed earlier deletions are not rolled back. Processing continues after item-local invalid or not-found responses, but stops after authentication, permission, rate-limit, server, or ambiguous transport failures. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_DELETE_WORKSPACE` | Delete Workspace | Permanently delete a workspace and its contained resources. This irreversible operation cannot be undone and requires repeating the workspace ID as explicit confirmation. Requires a personal access token with the workspaces-write ability. |
| `OPN_FORM_GET_CURRENT_USER` | Get Current User | Return the name and email of the OpnForm user associated with the connected personal access token. |
| `OPN_FORM_GET_FORM` | Get Form | Retrieve a form by its public slug, including its complete field and layout definitions. Requires a personal access token with the forms-read ability. |
| `OPN_FORM_INVITE_WORKSPACE_MEMBER` | Invite Workspace Member | Add an existing OpnForm user to a workspace or email an invitation to a new user. Sending an invitation email cannot be undone. OpnForm Cloud requires a Pro plan and a personal access token with the workspace-users-write ability. |
| `OPN_FORM_INVITE_WORKSPACE_MEMBERS` | Invite Workspace Members | Add or invite 1-10 users to one workspace through sequential provider requests. Each successful item may send an invitation email that cannot be undone, and the batch is not atomic. Processing continues after item-local validation failures but stops after authentication, permission, plan, rate-limit, server, or ambiguous transport failures. OpnForm Cloud requires a Pro plan and a personal access token with the workspace-users-write ability. |
| `OPN_FORM_LIST_FORM_INTEGRATIONS` | List Form Integrations | List webhook and Make integrations configured for a form, including IDs, status, and endpoint configuration. Requires a personal access token with the manage-integrations ability. |
| `OPN_FORM_LIST_FORMS` | List Forms | Return one page of lightweight form summaries from a workspace. Pass the returned cursor back to continue; use Get Form for complete field definitions. Requires a personal access token with the forms-read ability. |
| `OPN_FORM_LIST_INTEGRATION_EVENTS` | List Integration Events | Inspect past delivery attempts for one form integration, including the attempt date, Success or Error status, and a downstream HTTP status when available. Requires a personal access token with the manage-integrations ability. |
| `OPN_FORM_LIST_SUBMISSIONS` | List Submissions | Return one searchable page of completed, partial, or all submissions for a form. Pass the returned cursor back unchanged to continue with the same filters. Requires a personal access token with the forms-read ability. |
| `OPN_FORM_LIST_WORKSPACE_INVITES` | List Workspace Invites | List pending and accepted invitations for a workspace where the connected user is an administrator. Requires a personal access token with the workspaces-write ability. |
| `OPN_FORM_LIST_WORKSPACE_MEMBERS` | List Workspace Members | List members of a workspace with their user IDs, names, emails, and workspace roles. Requires a personal access token with the workspace-users-read ability. |
| `OPN_FORM_LIST_WORKSPACES` | List Workspaces | List workspaces accessible to the connected user, including IDs, plan tier, role flags, usage counts, enabled features, and plan limits. Requires a personal access token with the workspaces-read ability. |
| `OPN_FORM_REMOVE_WORKSPACE_MEMBER` | Remove Workspace Member | Remove a specified member from a workspace without deleting the member's OpnForm account. Requires a personal access token with the workspace-users-write ability. |
| `OPN_FORM_RESEND_WORKSPACE_INVITE` | Resend Workspace Invite | Send another invitation email for an existing pending workspace invite. Each successful call sends an external email to the invite recipient and requires a personal access token with the workspace-users-write ability. |
| `OPN_FORM_UPDATE_FORM` | Update Form | Replace or change an existing form's field definitions and settings using its numeric form ID. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_UPDATE_FORM_INTEGRATION` | Update Form Integration | Change a generic webhook integration's delivery URL or active status. Requires a personal access token with the manage-integrations ability. |
| `OPN_FORM_UPDATE_FORM_SUBMISSION_RETENTION` | Update Form Submission Retention | Change or disable a form's automatic submission-retention policy. Expired submissions are permanently deleted and cannot be restored; shortening the period can make existing submissions eligible for the next hourly cleanup. Requires a personal access token with the forms-write ability. |
| `OPN_FORM_UPDATE_WORKSPACE` | Update Workspace | Change a workspace's name and icon without affecting its membership or forms. Both values are required because OpnForm clears an omitted icon. Requires a personal access token with the workspaces-write ability. |
| `OPN_FORM_UPDATE_WORKSPACE_MEMBER_ROLE` | Update Workspace Member Role | Change an existing workspace member's role to admin, user, or readonly. Requires a personal access token with the workspace-users-write ability. |

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

## Conclusion

### Use OPNForm from Atomic Agent
With your account connected, ask Atomic Agent to work with OPNForm in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and OPNForm MCP?

With a standalone OPNForm MCP server, the agents and LLMs can only access a fixed set of OPNForm tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from OPNForm and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right OPNForm tools.

### Can I manage the permissions and scopes for OPNForm while using Tool Router?

Yes, absolutely. You can configure which OPNForm scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your OPNForm data and credentials are handled as safely as possible.
