# How to connect MailBluster to OpenClaw (paste one key, 15 tools) > Connect MailBluster to OpenClaw with ClawLink: paste your MailBluster key once and 15 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/mailbluster The usual route to MailBluster 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 MailBluster setup: install one ClawHub skill, connect MailBluster in the browser, and OpenClaw can call real MailBluster 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 MailBluster. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect MailBluster** — 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 mailbluster # connect MailBluster (browser OAuth) npx -y @useclawlink/cli actions mailbluster # list available actions npx -y @useclawlink/cli run mailbluster --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 MailBluster in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your MailBluster API key once. Verify the connection by asking OpenClaw: > Pull the relevant data from MailBluster, 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 MailBluster is connected in the dashboard, that agent calls the same 15 MailBluster tools over MCP.

ClawLink connects MailBluster to OpenClaw and exposes 15 MailBluster 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 MailBluster integration](https://claw-link.dev/hermes/mailbluster) works the same way. ## What the OpenClaw MailBluster integration can do 15 MailBluster tools are ready for OpenClaw once the account is connected. The 12 below are the ones people reach for most; your agent can call all 15. ### 12 of 15 MailBluster tools for OpenClaw | Tool | What it does | |---|---| | **Get lead** `mailbluster_get_lead` | Retrieve a specific lead's information using their lead hash (MD5 encrypted email address) | | **Get order** `mailbluster_get_order` | Retrieve details of a specific order | | **Get product** `mailbluster_get_product` | Retrieve details of a specific product | | **List fields** `mailbluster_list_fields` | List all custom fields | | **List orders** `mailbluster_list_orders` | List all orders | | **List products** `mailbluster_list_products` | List all products | | **Create lead** `mailbluster_create_lead` | Create a new lead in MailBluster | | **Create order** `mailbluster_create_order` | Create a new order in MailBluster | | **Create product** `mailbluster_create_product` | Create a new product in MailBluster | | **Update lead** `mailbluster_update_lead` | Update an existing lead's information in MailBluster | | **Update order** `mailbluster_update_order` | Update an existing order's customer details, currency, price, and items in MailBluster | | **Update product** `mailbluster_update_product` | Update a product in MailBluster by its ID | ## Example prompts **Get Lead** > Pull the relevant data from MailBluster, summarize it in plain English, and point out anything that needs attention. **Get Order** > Pull the relevant data from MailBluster, summarize it in plain English, and point out anything that needs attention. **Get Product** > Pull the relevant data from MailBluster, summarize it in plain English, and point out anything that needs attention. **List Fields** > List the relevant items in MailBluster, group them by priority, and recommend what OpenClaw should do next. ## 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 MailBluster working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the MailBluster API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected MailBluster 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 MailBluster. | 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 MailBluster actions to the runtime in a format your agent can reliably use. | 15 tools for MailBluster are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes MailBluster 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 MailBluster in the browser, and the 15 tools above work from chat. There is no SDK and no config file, and the MailBluster key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Make sure MailBluster 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 MailBluster 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 MailBluster tools MailBluster 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 MailBluster 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. ### MailBluster 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 MailBluster has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw MailBluster integration? Yes. ClawLink is the fastest way to connect OpenClaw to MailBluster: link your MailBluster account once in the browser and OpenClaw can call the MailBluster API through 15 ready-made tools — no custom code or token handling. ### How do I add MailBluster to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink MailBluster skill from ClawHub, then you click Connect in the dashboard to authorize MailBluster. OpenClaw calls the tools from the next message — no config files, and the MailBluster key you paste is stored server-side instead of in your environment. ### How long does it take to connect MailBluster to OpenClaw? About two minutes. Sign in, click Connect next to MailBluster in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring MailBluster 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 MailBluster working from chat. ### OpenClaw installed the MailBluster skill but can't call the tools The ClawHub skill teaches OpenClaw about MailBluster, but the calls run through the ClawLink plugin and your connected account.
