How to connect Nutshell to Hermes Agent
Connect Nutshell to Hermes with ClawLink: paste your Nutshell key once and 78 tools work from chat. No MCP server to run, nothing stored on your machine.
NutshellBASIC AUTHMCPNutshell is a flexible CRM and email marketing platform that helps small businesses manage contacts, sales pipelines, and customer relationships.. Once connected, Hermes Agent can read and act on Nutshell from chat — pairing, token refresh, and tool wiring handled for you.
Most guides for giving Hermes Agent Nutshell 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 Nutshell setup: pair once in the browser and your always-on Hermes agent can act on Nutshell 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 Nutshell.
1Install 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 Nutshell
Enter your account details in the dashboard.

Use it from chat
Ask Hermes Agent: "What can you do with Nutshell?"
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 testThen connect Nutshell in the ClawLink dashboard — enter your Nutshell account details once.
Verify the connection by asking Hermes:
Pull the relevant data from Nutshell, 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 loginlogin opens the same browser approval and stores a credential locally. Once Nutshell is connected in the dashboard, that agent calls the same 78 Nutshell 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 credential 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 Nutshell working from chat.
| Manual | ClawLink | |
|---|---|---|
| Setup flow | Collect and store the right Nutshell credentials yourself, then keep the account mapping and request format correct. | ClawLink keeps the setup in one hosted flow so non-technical users can link Nutshell without custom integration screens. |
| Ongoing maintenance | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Nutshell. | 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 Nutshell actions to the runtime in a format your agent can reliably use. | 78 tools for Nutshell are already exposed through ClawLink, so the agent can read and act from chat immediately. |
ClawLink vs. Composio
Composio also exposes Nutshell 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 Nutshell in the browser, and the 78 tools above work from chat. There is no SDK and no config file, and the Nutshell 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 Nutshell
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 Nutshell 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 Nutshell tools
Nutshell 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 Nutshell 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.
Nutshell 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.
The setup form accepts credentials but calls still fail
Re-enter the credentials carefully and verify the account-level permissions for Nutshell. Basic and token-based integrations tend to fail on formatting mistakes or limited account roles.
