# How to connect MailerLite to OpenClaw (paste one key, 86 tools) > Connect MailerLite to OpenClaw with ClawLink: paste your MailerLite key once and 86 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/mailerlite The usual route to MailerLite 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 MailerLite setup: install one ClawHub skill, connect MailerLite in the browser, and OpenClaw can call real MailerLite actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. **Start here:** install the ClawLink plugin (`openclaw plugins install clawhub:clawlink-plugin`), pair it in the browser, then connect the app in the ClawLink dashboard. The interactive install prompt is on the web version of this page: https://claw-link.dev/openclaw/mailerlite ## Setup It takes three steps to connect OpenClaw to MailerLite. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect MailerLite** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **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 mailerlite # connect MailerLite (browser OAuth) npx -y @useclawlink/cli actions mailerlite # list available actions npx -y @useclawlink/cli run mailerlite --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 MailerLite in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your MailerLite API key once. Verify the connection by asking OpenClaw: > Use MailerLite to add subscriber to group and walk me through the result in plain English. ### 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 MailerLite is connected in the dashboard, that agent calls the same 86 MailerLite tools over MCP.

ClawLink connects MailerLite to OpenClaw and exposes 86 MailerLite 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 MailerLite integration](https://claw-link.dev/hermes/mailerlite) works the same way. ## What the OpenClaw MailerLite integration can do 86 MailerLite tools are ready for OpenClaw once the account is connected. The 30 below are the ones people reach for most; your agent can call all 86. ### 30 of 86 MailerLite tools for OpenClaw | Tool | What it does | |---|---| | **Add subscriber to group** `mailerlite_add_subscriber_to_group` | Add a subscriber to a MailerLite group | | **Create campaign** `mailerlite_create_campaign` | Create a MailerLite campaign | | **Create field** `mailerlite_create_field` | Create a MailerLite custom field | | **Create group** `mailerlite_create_group` | Create a MailerLite group | | **Create segment** `mailerlite_create_segment` | Create a MailerLite segment | | **Create subscriber** `mailerlite_create_subscriber` | Create a MailerLite subscriber | | **Get account info** `mailerlite_get_account_info` | Get MailerLite account information | | **Get account stats** `mailerlite_get_account_stats` | Get MailerLite account statistics | | **Get automation** `mailerlite_get_automation` | Get a MailerLite automation | | **Get campaigns** `mailerlite_get_campaigns` | List MailerLite campaigns | | **Get fields** `mailerlite_get_fields` | List MailerLite custom fields | | **Get groups** `mailerlite_get_groups` | List MailerLite groups | | **Get subscriber** `mailerlite_get_subscriber` | Get a MailerLite subscriber by ID | | **Update subscriber** `mailerlite_update_subscriber` | Update a MailerLite subscriber | | **Get automation activity** `mailerlite_get_automation_activity` | Retrieve subscriber activity for a specific automation | | **Get campaign languages** `mailerlite_get_campaign_languages` | Retrieve a list of all available campaign languages | | **Get ecommerce cart** `mailerlite_get_ecommerce_cart` | Fetch details of a specific cart by shop ID and cart ID | | **Get ecommerce cart item** `mailerlite_get_ecommerce_cart_item` | Fetch details of a specific cart item by shop ID, cart ID, and item ID | | **Get ecommerce category** `mailerlite_get_ecommerce_category` | Fetch details of a specific product category by shop and category ID | | **Get ecommerce customer** `mailerlite_get_ecommerce_customer` | Fetch details of a customer by shop and customer ID | | **Get ecommerce customers** `mailerlite_get_ecommerce_customers` | List customers for a specific shop | | **Get ecommerce order** `mailerlite_get_ecommerce_order` | Fetch details of a specific e-commerce order by shop ID and order ID | | **Get ecommerce product** `mailerlite_get_ecommerce_product` | Fetch details of a specific e-commerce product by shop and product ID | | **Get ecommerce shop** `mailerlite_get_ecommerce_shop` | Fetch details of a specific e-commerce shop by ID | | **Get ecommerce shops** `mailerlite_get_ecommerce_shops` | List all e-commerce shops connected to the account | | **Get group** `mailerlite_get_group` | Retrieve details of a specific subscriber group by ID | | **Get group subscribers** `mailerlite_get_group_subscribers` | List subscribers within a group by ID | | **Get import status** `mailerlite_get_import_status` | Retrieve the status and detailed report of a subscriber import operation by import ID | | **Get segment** `mailerlite_get_segment` | Retrieve a specific segment by ID | | **Get segment subscribers** `mailerlite_get_segment_subscribers` | Retrieve all subscribers belonging to a specific segment | ## Example prompts **Add Subscriber To Group** > Use MailerLite to add subscriber to group and walk me through the result in plain English. **Create Campaign** > Create it in MailerLite for me, then confirm the important fields before you finish. **Create Field** > Create it in MailerLite for me, then confirm the important fields before you finish. **Create Group** > Create it in MailerLite 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 MailerLite working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the MailerLite API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected MailerLite 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 MailerLite. | 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 MailerLite actions to the runtime in a format your agent can reliably use. | 86 tools for MailerLite are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes MailerLite 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 MailerLite in the browser, and the 86 tools above work from chat. There is no SDK and no config file, and the MailerLite key you paste at setup is stored server-side rather than kept in your environment. Choosing between them? Read the full [Composio alternatives](https://claw-link.dev/hub/composio-alternatives) comparison. ### OpenClaw installed the MailerLite skill but can't call the tools The ClawHub skill teaches OpenClaw about MailerLite, but the calls run through the ClawLink plugin and your connected account. Make sure MailerLite 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 MailerLite 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 MailerLite tools MailerLite 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 MailerLite 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. ### MailerLite 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 MailerLite has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw MailerLite integration? Yes. ClawLink is the fastest way to connect OpenClaw to MailerLite: link your MailerLite account once in the browser and OpenClaw can call the MailerLite API through 86 ready-made tools — no custom code or token handling. ### How do I add MailerLite to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink MailerLite skill from ClawHub, then you click Connect in the dashboard to authorize MailerLite. OpenClaw calls the tools from the next message — no config files, and the MailerLite key you paste is stored server-side instead of in your environment. ### How long does it take to connect MailerLite to OpenClaw? About two minutes. Sign in, click Connect next to MailerLite in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring MailerLite 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 MailerLite working from chat. ### OpenClaw installed the MailerLite skill but can't call the tools The ClawHub skill teaches OpenClaw about MailerLite, but the calls run through the ClawLink plugin and your connected account.
