CertSeal provides APIs for issuing and managing verifiable digital certificates, recipients, batches, designs, and webhook subscriptions.. Once connected, OpenClaw can read and act on CertSeal from chat — pairing, token refresh, and tool wiring handled for you.

21 tools

The usual route to CertSeal access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical CertSeal setup: install one ClawHub skill, connect CertSeal in the browser, and OpenClaw can call real CertSeal actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.

Setup

It takes three steps to connect OpenClaw to CertSeal.

  1. 1

    Install the plugin

    Paste the setup prompt into OpenClaw, or install from the terminal and ask OpenClaw to pair:

    openclaw plugins install clawhub:clawlink-plugin
  2. 2

    Connect CertSeal

    Paste your API key in the dashboard.

  3. 3

    Use it from chat

    Ask OpenClaw: "What can you do with CertSeal?"

Install by command

The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval:

openclaw plugins install clawhub:clawlink-plugin

Then ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say done. Finally, connect CertSeal in the ClawLink dashboard — paste your CertSeal API key once.

Verify the connection by asking OpenClaw:

Pull the relevant data from CertSeal, summarize it in plain English, and point out anything that needs attention.

Using a different agent?

The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI:

npx -y @useclawlink/cli login

login opens the same browser approval and stores a credential locally. Once CertSeal is connected in the dashboard, that agent calls the same 21 CertSeal tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

The alternative to ClawLink is usually manual API key setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want CertSeal working from chat.

ManualClawLink
Credential handlingCollect, validate, store, and rotate the CertSeal API key yourself, then make sure every tool call uses the right account.Users complete the hosted ClawLink setup once and the connected CertSeal account becomes available to the agent without you building credential management.
Ongoing maintenanceYou own refresh logic, permission debugging, environment config, and every provider-specific edge case for CertSeal.ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure.
Agent usabilityYou still need to expose the right CertSeal actions to the runtime in a format your agent can reliably use.21 tools for CertSeal are already exposed through ClawLink, so the agent can read and act from chat immediately.

Composio also exposes CertSeal to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for OpenClaw users instead. You install the plugin once, connect CertSeal in the browser, and the 21 tools above work from chat. There is no SDK and no config file, and the CertSeal key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting

OpenClaw installed the CertSeal skill but can't call the tools

The ClawHub skill teaches OpenClaw about CertSeal, but the calls run through the ClawLink plugin and your connected account. Make sure CertSeal is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register.

Connection succeeds but no tools appear

Reconnect CertSeal from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.

"Tool schema not loaded yet" error when calling CertSeal tools

CertSeal tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every CertSeal call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again.

CertSeal returns 403 or "permission denied" on one action while others work

Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs.

API key setup works but results look incomplete

Double-check that the API key for CertSeal has the right scopes or account access. A valid key can still be too limited for some reads or writes.
