# How to connect Mailercloud to OpenClaw (paste one key, 6 tools) > Connect Mailercloud to OpenClaw with ClawLink: paste your Mailercloud key once and 6 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/mailercloud The usual route to Mailercloud 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 Mailercloud setup: install one ClawHub skill, connect Mailercloud in the browser, and OpenClaw can call real Mailercloud 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 Mailercloud. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Mailercloud** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **Paste this into OpenClaw to set up ClawLink:** > I want to connect my apps to OpenClaw through ClawLink. > Please install the ClawLink plugin from ClawHub and enable it: `openclaw plugins install clawhub:clawlink-plugin` > When it is installed, tell me and stop. After I reply, give me the ClawLink pairing link. Setup notes, if you need them: https://claw-link.dev/skill.md **Alternative for any agent (no plugin needed):** if the OpenClaw 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 mailercloud # connect Mailercloud (browser OAuth) npx -y @useclawlink/cli actions mailercloud # list available actions npx -y @useclawlink/cli run mailercloud --input '' # execute (add --confirm for writes) ``` ### 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: ```bash 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 Mailercloud in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Mailercloud API key once. Verify the connection by asking OpenClaw: > Pull the relevant data from Mailercloud, 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: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Mailercloud is connected in the dashboard, that agent calls the same 6 Mailercloud tools over MCP.

ClawLink connects Mailercloud to OpenClaw and exposes 6 Mailercloud 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 Hermes instead? The [Hermes Mailercloud integration](https://claw-link.dev/hermes/mailercloud) works the same way. ## What the OpenClaw Mailercloud integration can do 6 Mailercloud tools are ready for OpenClaw once the account is connected. The 5 below are the ones people reach for most; your agent can call all 6. ### 5 of 6 Mailercloud tools for OpenClaw | Tool | What it does | |---|---| | **Get client plan** `mailercloud_get_client_plan` | Retrieve client plan information from Mailercloud | | **Search contacts** `mailercloud_search_contacts` | Retrieve contacts in a specific list with pagination | | **Create list** `mailercloud_create_list` | Create a new recipient list in Mailercloud for storing and managing contacts | | **Create property** `mailercloud_create_property` | Create a custom property for contacts in Mailercloud | | **Update property** `mailercloud_update_property` | Update a custom property of contacts in Mailercloud | ## Example prompts **Get Client Plan** > Pull the relevant data from Mailercloud, summarize it in plain English, and point out anything that needs attention. **Search Contacts** > Search Mailercloud for what I need, summarize the results, and tell me the next best action. **Create List** > Create it in Mailercloud for me, then confirm the important fields before you finish. **Create Property** > Create it in Mailercloud for me, then confirm the important fields before you finish. ## 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 OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Mailercloud working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Mailercloud API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Mailercloud 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 Mailercloud. | 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 Mailercloud actions to the runtime in a format your agent can reliably use. | 6 tools for Mailercloud are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Mailercloud 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 Mailercloud in the browser, and the 6 tools above work from chat. There is no SDK and no config file, and the Mailercloud key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Make sure Mailercloud 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 Mailercloud 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 Mailercloud tools Mailercloud 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 Mailercloud 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. ### Mailercloud 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 Mailercloud has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw Mailercloud integration? Yes. ClawLink is the fastest way to connect OpenClaw to Mailercloud: link your Mailercloud account once in the browser and OpenClaw can call the Mailercloud API through 6 ready-made tools — no custom code or token handling. ### How do I add Mailercloud to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Mailercloud skill from ClawHub, then you click Connect in the dashboard to authorize Mailercloud. OpenClaw calls the tools from the next message — no config files, and the Mailercloud key you paste is stored server-side instead of in your environment. ### How long does it take to connect Mailercloud to OpenClaw? About two minutes. Sign in, click Connect next to Mailercloud in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Mailercloud up myself? 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 Mailercloud working from chat. ### OpenClaw installed the Mailercloud skill but can't call the tools The ClawHub skill teaches OpenClaw about Mailercloud, but the calls run through the ClawLink plugin and your connected account. Make sure Mailercloud 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. ## Related - [ActiveCampaign tools](https://claw-link.dev/openclaw/activecampaign) — Marketing automation, CRM, and email marketing - [Benchmark Email](https://claw-link.dev/openclaw/benchmark-email) — Benchmark Email is a comprehensive email marketing platform offering tools for creating, sending, and analyzing email campaigns. - [Mailchimp tools](https://claw-link.dev/openclaw/mailchimp) — Create email campaigns and manage audiences
