## Introduction

### How to connect CertSeal MCP with ChatGPT Work
[ChatGPT Work](https://openai.com/chatgpt-work/) is an agent inside ChatGPT built for your most ambitious work. It takes action across your apps and files, stays with a project for hours, and turns a goal into finished materials like sheets, slides, and docs - not just answers.
In this guide, I will explain the easiest and most secure way to connect your CertSeal account to ChatGPT Work via Composio Connect, so it can issue certificates for completed training batch, list pending certseal certificate recipients, create webhook for issued certificates through natural language commands without ever putting your account credentials at risk.

- [Hermes](https://composio.dev/toolkits/cert_seal/framework/hermes-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's CertSeal integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,000+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect CertSeal to ChatGPT Work

### Prerequisites
- A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan.
- Access to the CertSeal workspace you want to connect.
- [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect CertSeal to ChatGPT Work
### 1. Open the MCP settings
In ChatGPT Work, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CERT_SEAL_CREATE_BATCH` | Create Batch | Create a persistent certificate batch from an existing CertSeal design and optional email template. This consumes a batch slot and can fail when the plan batch limit is reached; designs and templates must already exist and are not created by this tool. |
| `CERT_SEAL_CREATE_WEBHOOK_SUBSCRIPTION` | Create Webhook Subscription | Create a persistent webhook subscription for selected certificate events. The response contains a wh_sec_ signing secret exactly once; capture it immediately and store it securely because later reads reveal only its tail. The workspace allows at most 20 subscriptions. |
| `CERT_SEAL_DELETE_RECIPIENT` | Delete Recipient | Permanently delete an issued recipient from an active batch. This cannot be undone, does not refund certificate quota, and permanently burns the certificate ID. Use only when permanent removal is intended. |
| `CERT_SEAL_DELETE_WEBHOOK_SUBSCRIPTION` | Delete Webhook Subscription | Permanently delete a webhook subscription and stop future deliveries. This cannot be undone; create a new subscription to resume events. |
| `CERT_SEAL_GET_BATCH` | Get Batch | Get one active or archived certificate batch by ID. |
| `CERT_SEAL_GET_CERTIFICATE` | Get Certificate | Look up an issued certificate using either its human-readable certificate ID or its public-viewer share token, and return its recipient, batch, design, and resolved variables. Provide exactly one lookup value. |
| `CERT_SEAL_GET_CURRENT_WORKSPACE` | Get Current Workspace | Verify the connected CertSeal API key and return the workspace ID and username it belongs to. Use this to confirm account context before creating or changing resources. |
| `CERT_SEAL_GET_RECIPIENT` | Get Recipient | Get one issued certificate recipient record by batch ID and recipient ID. |
| `CERT_SEAL_GET_WEBHOOK_SUBSCRIPTION` | Get Webhook Subscription | Get one webhook subscription by ID. This does not reveal the signing secret; it returns only the stored secret tail. |
| `CERT_SEAL_ISSUE_AND_SEND_CERTIFICATES` | Issue and Send Certificates | Atomically issue certificates for 1-100 recipients and queue email delivery for every created certificate. This irreversible external side effect requires every recipient to have an email address and the active batch to have an email template and configured mail delivery. Each recipient permanently consumes one certificate quota unit. |
| `CERT_SEAL_ISSUE_CERTIFICATES` | Issue Certificates | Atomically issue certificates without sending email for 1-100 recipients in one active batch. Each recipient permanently consumes one certificate quota unit even if later deleted; any invalid row, duplicate certificate ID, or quota failure creates none. |
| `CERT_SEAL_LIST_BATCHES` | List Batches | Return one newest-first page of certificate batches in the connected workspace, optionally filtered by archive state. |
| `CERT_SEAL_LIST_DESIGNS` | List Designs | Return one newest-first page of reusable certificate designs. Designs are read-only through the API and must be authored in the CertSeal web app. |
| `CERT_SEAL_LIST_RECIPIENTS` | List Recipients | Return one page of issued certificate recipients in a batch, optionally filtered by email delivery status. |
| `CERT_SEAL_LIST_WEBHOOK_SUBSCRIPTIONS` | List Webhook Subscriptions | Return one newest-first page of webhook subscriptions. Stored signing secrets are never returned; secret_tail is only a non-sensitive identifier. |
| `CERT_SEAL_ROTATE_WEBHOOK_SIGNING_SECRET` | Rotate Webhook Signing Secret | Immediately invalidate a webhook subscription's current signing secret and replace it. The new wh_sec_ secret is returned exactly once; capture and deploy it immediately or webhook verification will fail. |
| `CERT_SEAL_SEND_CERTIFICATE_EMAILS` | Send Certificate Emails | Sequentially queue real certificate emails for 1-25 existing recipients in one active batch. Each queued email is irreversible. Processing stops after the first failed or unknown attempt, and remaining recipients are marked not_attempted. |
| `CERT_SEAL_SEND_RECIPIENT_CERTIFICATE_EMAIL` | Send Recipient Certificate Email | Queue asynchronous certificate email delivery to one recipient. This causes an external email side effect and requires a recipient email, a batch email template, and configured mail delivery; already queued or in-flight recipients and archived batches are rejected. |
| `CERT_SEAL_SET_BATCH_ARCHIVED` | Set Batch Archived State | Idempotently archive or unarchive a batch. Archiving freezes recipient create, update, delete, and send operations but preserves existing certificate URLs; unarchiving re-enables those writes. This persistent change is reversible. |
| `CERT_SEAL_TEST_WEBHOOK_SUBSCRIPTION` | Test Webhook Subscription | Enqueue one synthetic signed event through CertSeal's normal webhook dispatcher. This causes a real external delivery to the subscription URL; it does not only validate the subscription locally. |
| `CERT_SEAL_UPDATE_RECIPIENT` | Update Recipient | Partially update an issued certificate recipient. Only supplied fields change, while an explicit null clears an optional field; changing certificate_id must remain globally unique. Archived batches reject this mutation. |

## Frequently Asked Questions

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

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

### Can I use Tool Router MCP with ChatGPT Work?

Yes, you can. ChatGPT Work 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 CertSeal tools.

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

Yes, absolutely. You can configure which CertSeal 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 CertSeal data and credentials are handled as safely as possible.
