Api Key

CertSeal is an API platform for issuing and managing verifiable digital certificates. Use it to automate trusted certificate workflows for recipients, batches, designs, and webhooks.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your CertSeal account to Claude via Composio Connect, enabling it to issue certificates for completed training batch, list pending CertSeal certificate recipients, create webhook for issued certificates, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting CertSeal to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your CertSeal account

Back in Claude, ask it to connect to CertSeal or give it any CertSeal-related task.

For example, ask Claude to:

  • "Issue certificates for completed training batch"
  • "List pending CertSeal certificate recipients"
  • "Create webhook for issued certificates"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your CertSeal account is ready to use.

What is the CertSeal Claude Connector, 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.

Troubleshooting

1. Why does Claude not use the Composio connector for CertSeal?

The connector can show as connected, but Claude must use it in each CertSeal conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to CertSeal again.

2. Why does Claude show an MCP server error before CertSeal connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for CertSeal.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect CertSeal.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the CertSeal authorization link not work?

The Composio connector is one server. Your CertSeal account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the CertSeal connection.
  • Composio creates a fresh CertSeal authorization link.
  • Open that link in your browser and finish the CertSeal sign-in.

4. Why do CertSeal actions fail after they worked before?

The CertSeal connection can expire or lose permission.

  • Ask Claude to inspect the CertSeal connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the CertSeal account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in CertSeal.
  • If the action still fails with a permission error, check that the connected account has that permission in CertSeal itself.

5. How do I switch to a different CertSeal account?

Claude can manage the CertSeal connection for you.

  • Ask Claude to disconnect or delete the current CertSeal account.
  • Ask Claude to connect CertSeal again.
  • Open the new Composio authorization link for CertSeal.
  • Sign in with the other CertSeal account in the browser.
  • After the account connects, ask Claude to retry the CertSeal task.

6. Why is my CertSeal connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your CertSeal connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If CertSeal tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect CertSeal.

FAQ

Frequently asked questions

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.

Yes, you can. Claude Cowork 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.

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.

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.
