Hjarni is a personal knowledge management platform for organizing, searching, linking, and maintaining notes, containers, and tags.. Once connected, OpenClaw can read and act on Hjarni from chat — pairing, token refresh, and tool wiring handled for you.

15 tools

The usual route to Hjarni 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 Hjarni setup: install one ClawHub skill, connect Hjarni in the browser, and OpenClaw can call real Hjarni 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 Hjarni.

  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 Hjarni

    Paste your API key in the dashboard.

  3. 3

    Use it from chat

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

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 Hjarni in the ClawLink dashboard — paste your Hjarni API key once.

Verify the connection by asking OpenClaw:

Pull the relevant data from Hjarni, 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 Hjarni is connected in the dashboard, that agent calls the same 15 Hjarni 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 Hjarni working from chat.

ManualClawLink
Credential handlingCollect, validate, store, and rotate the Hjarni API key yourself, then make sure every tool call uses the right account.Users complete the hosted ClawLink setup once and the connected Hjarni 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 Hjarni.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 Hjarni actions to the runtime in a format your agent can reliably use.15 tools for Hjarni are already exposed through ClawLink, so the agent can read and act from chat immediately.

Composio also exposes Hjarni 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 Hjarni in the browser, and the 15 tools above work from chat. There is no SDK and no config file, and the Hjarni key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting

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

The ClawHub skill teaches OpenClaw about Hjarni, but the calls run through the ClawLink plugin and your connected account. Make sure Hjarni 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 Hjarni 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 Hjarni tools

Hjarni 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 Hjarni 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.

Hjarni 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 Hjarni has the right scopes or account access. A valid key can still be too limited for some reads or writes.
