How to connect Quaderno to OpenClaw
Connect Quaderno to OpenClaw with ClawLink: paste your Quaderno key once and 76 tools work from chat. No MCP server to run, nothing stored on your machine.
QuadernoAPI KEYMCPQuaderno is a tax compliance platform that automates tax calculations, invoicing, and reporting for businesses worldwide.. Once connected, OpenClaw can read and act on Quaderno from chat — pairing, token refresh, and tool wiring handled for you.
The usual route to Quaderno 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 Quaderno setup: install one ClawHub skill, connect Quaderno in the browser, and OpenClaw can call real Quaderno actions from any chat surface with no auth, token refresh, or tool wiring to build yourself.

Use it from chat
Ask OpenClaw: "What can you do with Quaderno?"
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-pluginThen 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 Quaderno in the ClawLink dashboard — paste your Quaderno API key once.
Verify the connection by asking OpenClaw:
Use Quaderno to calculate tax rate and walk me through the result in plain English.
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 loginlogin opens the same browser approval and stores a credential locally. Once Quaderno is connected in the dashboard, that agent calls the same 76 Quaderno tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

ClawLink vs. building it yourself
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 Quaderno working from chat.
| Manual | ClawLink | |
|---|---|---|
| Credential handling | Collect, validate, store, and rotate the Quaderno API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Quaderno account becomes available to the agent without you building credential management. |
| Ongoing maintenance | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Quaderno. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. |
| Agent usability | You still need to expose the right Quaderno actions to the runtime in a format your agent can reliably use. | 76 tools for Quaderno are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Quaderno 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 Quaderno in the browser, and the 76 tools above work from chat. There is no SDK and no config file, and the Quaderno key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting
OpenClaw installed the Quaderno skill but can't call the tools
The ClawHub skill teaches OpenClaw about Quaderno, but the calls run through the ClawLink plugin and your connected account. Make sure Quaderno 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 Quaderno 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 Quaderno tools
Quaderno 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 Quaderno 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.
Quaderno 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 Quaderno has the right scopes or account access. A valid key can still be too limited for some reads or writes.
