Most guides for giving Hermes Agent Dart 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 Dart setup: pair once in the browser and your always-on Hermes agent can act on Dart for you, reading and doing real work on your behalf with no auth, token refresh, or tool wiring to build yourself.

Dart MCP for Hermes

Looking for a Dart MCP server for Hermes Agent? ClawLink connects Dart to Hermes Agent and exposes 0 Dart tools your agent can call over MCP, with hosted auth and nothing to run or maintain yourself. Using OpenClaw instead? The OpenClaw Dart integration works the same way.

Copy this prompt into Hermes to install the plugin and pair your account.

Prompt for Hermes
Set up ClawLink for Hermes and tell me when it's ready.

1. Install the plugin:
hermes plugins install ClawLink-HQ/hermes-plugin --enable

2. Start pairing. It prints an approval link, so show me the link and stop, don't wait:
hermes clawlink begin

3. I'll approve it in my browser, then reply "approved".

4. When I say approved, finish setup:
hermes clawlink finish

5. Then run `hermes clawlink test` and tell me whether ClawLink is ready.

What the Hermes Agent Dart integration can do

  • Productivity — tools appear after Dart is connected.

Try it: find the Dart tool you need

Example prompts

No example prompts are available yet.

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 Dart working from chat.

ManualClawLink
Credential handlingCollect, validate, store, and rotate the Dart API key yourself, then make sure every tool call uses the right account.Users complete the hosted ClawLink setup once and the connected Dart 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 Dart.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 Dart actions to the runtime in a format your agent can reliably use.0 tools for Dart are already exposed through ClawLink, so the agent can read and act from chat immediately.

Composio also exposes Dart 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 Dart in the browser, and the connected Dart account works from chat. There is no SDK, no config file, and no API key handling. Choosing between them? Read the full Composio alternatives comparison.

Troubleshooting

Hermes paired but still can't use Dart

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 Dart 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 Dart tools

Dart 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 Dart 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.

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