How to connect Grafbase to Hermes Agent (paste one key, 28 tools)

Most guides for giving Hermes Agent Grafbase access start with registering your own OAuth app or pasting API keys into env files, then leave the token refresh and tool wiring to you. ClawLink gives Hermes a more practical Grafbase setup: pair once in the browser and your always-on Hermes agent can act on Grafbase for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.

Setup

It takes three steps to connect Hermes to Grafbase.

1
Install and pair
Install the ClawLink plugin, then pair Hermes with a one-time browser approval:
hermes plugins install ClawLink-HQ/hermes-plugin --enable
2
Connect Grafbase
Paste your API key in the dashboard.
3
Use it from chat
Ask Hermes Agent: "What can you do with Grafbase?"

Install by command

The prompt above walks Hermes through this. By hand, it is four commands and a browser approval:

hermes plugins install ClawLink-HQ/hermes-plugin --enable
hermes clawlink begin    # prints an approval link — open it and approve
hermes clawlink finish   # after approving in the browser
hermes clawlink test

Then connect Grafbase in the ClawLink dashboard — paste your Grafbase API key once.

Verify the connection by asking Hermes:

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

Using a different agent?

The Hermes 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 Grafbase is connected in the dashboard, that agent calls the same 28 Grafbase tools over MCP. Full setup for MCP clients and shell agents: connect apps to any AI agent.

Grafbase MCP for Hermes

Looking for a Grafbase MCP server for Hermes Agent? ClawLink connects Grafbase to Hermes Agent and exposes 28 Grafbase tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using OpenClaw instead? The OpenClaw Grafbase integration works the same way.

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 Hermes Agent. That is fine if you want to build and maintain the integration yourself. Most teams just want Grafbase working from chat.

	Manual	ClawLink
Credential handling	Collect, validate, store, and rotate the Grafbase API key yourself, then make sure every tool call uses the right account.	Users complete the hosted ClawLink setup once and the connected Grafbase 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 Grafbase.	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 Grafbase actions to the runtime in a format your agent can reliably use.	28 tools for Grafbase are already exposed through ClawLink, so the agent can read and act from chat immediately.

ClawLink vs. Composio

Composio also exposes Grafbase 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 Hermes Agent users instead. You install the plugin once, connect Grafbase in the browser, and the 28 tools above work from chat. There is no SDK and no config file, and the Grafbase key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Troubleshooting

Hermes paired but still can't use Grafbase

Pairing is a two-step handshake: run hermes clawlink begin, approve the link in your browser, then run hermes clawlink finish. If you ran finish before approving, or the approval link expired, run hermes clawlink begin again to get a fresh link. Confirm the plugin was installed with --enable, then verify with hermes clawlink test.

Connection succeeds but no tools appear

Reconnect Grafbase 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 Grafbase tools

Grafbase 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 Grafbase 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.

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