# How to connect Cardly to Hermes Agent (paste one key, 29 tools) > Connect Cardly to Hermes with ClawLink: paste your Cardly key once and 29 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/hermes/cardly Most guides for giving Hermes Agent Cardly 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 Cardly setup: pair once in the browser and your always-on Hermes agent can act on Cardly 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 Cardly. 1. **Install ClawLink** — add the plugin to Hermes Agent once. 2. **Connect Cardly** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask Hermes Agent in plain English. **Paste this into Hermes to set up ClawLink:** > 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 with `hermes clawlink begin`. It prints an approval link, so show me the link and stop, don't wait. > 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. **Alternative for any agent (no plugin needed):** if the Hermes Agent plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect cardly # connect Cardly (browser OAuth) npx -y @useclawlink/cli actions cardly # list available actions npx -y @useclawlink/cli run cardly --input '' # execute (add --confirm for writes) ``` ### Install by command The prompt above walks Hermes through this. By hand, it is four commands and a browser approval: ```bash 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 Cardly in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Cardly API key once. Verify the connection by asking Hermes: > Use Cardly to echo request and walk me through the result in plain English. ### 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: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Cardly is connected in the dashboard, that agent calls the same 29 Cardly tools over MCP.

ClawLink connects Cardly to Hermes Agent and exposes 29 Cardly tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using OpenClaw instead? The [OpenClaw Cardly integration](https://claw-link.dev/openclaw/cardly) works the same way. ## What the Hermes Agent Cardly integration can do 29 Cardly tools are ready for Hermes Agent once the account is connected. The 24 below are the ones people reach for most; your agent can call all 29. ### 24 of 29 Cardly tools for Hermes | Tool | What it does | |---|---| | **Echo request** `cardly_echo_request` | Echo all request parameters, body, and headers for debugging purposes | | **Generate preview** `cardly_generate_preview` | Generate a low-quality, watermarked preview document for a card | | **Get artwork** `cardly_get_artwork` | Retrieve information on a specific piece of artwork by its unique ID | | **Get webhook** `cardly_get_webhook` | Get details on an existing webhook | | **List artwork** `cardly_list_artwork` | Retrieve the currently available artwork for your organisation | | **List contact lists** `cardly_list_contact_lists` | Retrieve all active contact lists for your organization | | **List credit history** `cardly_list_credit_history` | Retrieves the account's credit transaction history showing all credits and debits | | **List doodles** `cardly_list_doodles` | Retrieve your currently available doodles from Cardly | | **List fonts** `cardly_list_fonts` | List available fonts for handwriting and text personalization in Cardly cards | | **List gift credit history** `cardly_list_gift_credit_history` | Lists gift credit history records for your organization with pagination and optional time-based | | **List invitations** `cardly_list_invitations` | Retrieve active invitations for your organisation with optional filters | | **List media** `cardly_list_media` | Retrieve the currently available media sizes for product artwork | | **List orders** `cardly_list_orders` | Retrieves a paginated list of orders placed by your organization | | **List templates** `cardly_list_templates` | Retrieve your currently available templates from Cardly | | **List users** `cardly_list_users` | Retrieve all users associated with your account | | **List webhooks** `cardly_list_webhooks` | Retrieves all webhooks configured for your organization, including their status, target URLs | | **List writing styles** `cardly_list_writing_styles` | List available writing styles | | **Retrieve account balance** `cardly_retrieve_account_balance` | Retrieve the current account and gift credit balances for your organisation | | **Retrieve order** `cardly_retrieve_order` | Retrieves detailed information about a specific order by its ID | | **Retrieve user** `cardly_retrieve_user` | Retrieves detailed information about a specific user account by ID | | **Create contact list** `cardly_create_contact_list` | Add a new contact list | | **Create invitation** `cardly_create_invitation` | Send an invitation to use your organisation portal | | **Create webhook** `cardly_create_webhook` | Create a new webhook subscription | | **Update webhook** `cardly_update_webhook` | Update a webhook’s settings, including target URL and events | ## Example prompts **Echo Request** > Use Cardly to echo request and walk me through the result in plain English. **Generate Preview** > Use Cardly to generate preview and walk me through the result in plain English. **Get Artwork** > Pull the relevant data from Cardly, summarize it in plain English, and point out anything that needs attention. **Get Webhook** > Pull the relevant data from Cardly, summarize it in plain English, and point out anything that needs attention. ## 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 Cardly working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Cardly API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Cardly 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 Cardly. | 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 Cardly actions to the runtime in a format your agent can reliably use. | 29 tools for Cardly are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Cardly 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 Cardly in the browser, and the 29 tools above work from chat. There is no SDK and no config file, and the Cardly key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

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 Cardly 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 Cardly tools Cardly 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 Cardly 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. ### Cardly 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 Cardly has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a Hermes Agent Cardly integration? Yes. ClawLink is the fastest way to connect Hermes to Cardly: link your Cardly account once in the browser and Hermes Agent can call the Cardly API through 29 ready-made tools — no custom code or token handling. ### How do I connect Cardly to Hermes with ClawLink? Install the plugin with `hermes plugins install ClawLink-HQ/hermes-plugin --enable`, then pair once: run `hermes clawlink begin`, approve the link in your browser, and run `hermes clawlink finish`. Connect Cardly in the dashboard and Hermes can use it from the next message — no config files, and the Cardly key you paste is stored server-side instead of in your environment. ### How long does it take to connect Cardly to Hermes Agent? About two minutes. Sign in, click Connect next to Cardly in the dashboard, authenticate, and Hermes Agent can use it from the next chat message. ### Why use ClawLink instead of wiring Cardly up myself? 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 Cardly working from chat. ### Hermes paired but still can't use Cardly 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.
