# How to connect Classmarker to OpenClaw (paste one key, 28 tools) > Connect Classmarker to OpenClaw with ClawLink: paste your Classmarker key once and 28 tools work from chat. No MCP server to run, nothing stored on your machine. Web version: https://claw-link.dev/openclaw/classmarker The usual route to Classmarker 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 Classmarker setup: install one ClawHub skill, connect Classmarker in the browser, and OpenClaw can call real Classmarker 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 Classmarker. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Classmarker** — 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 classmarker # connect Classmarker (browser OAuth) npx -y @useclawlink/cli actions classmarker # list available actions npx -y @useclawlink/cli run classmarker --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 Classmarker in the [ClawLink dashboard](https://claw-link.dev/dashboard) — paste your Classmarker API key once. Verify the connection by asking OpenClaw: > Pull the relevant data from Classmarker, 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 Classmarker is connected in the dashboard, that agent calls the same 28 Classmarker tools over MCP.

ClawLink connects Classmarker to OpenClaw and exposes 28 Classmarker 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 Classmarker integration](https://claw-link.dev/hermes/classmarker) works the same way. ## What the OpenClaw Classmarker integration can do 28 Classmarker tools are ready for OpenClaw once the account is connected. The 22 below are the ones people reach for most; your agent can call all 28. ### 22 of 28 Classmarker tools for OpenClaw | Tool | What it does | |---|---| | **Get group details** `classmarker_get_group_details` | Retrieve detailed information about a specific group by ID | | **Get initial finished after timestamp** `classmarker_get_initial_finished_after_timestamp` | Compute the initial finishedAfterTimestamp for paginating ClassMarker test results | | **Get question** `classmarker_get_question` | Retrieve a specific question by its ID | | **Get recent results group exam** `classmarker_get_recent_results_group_exam` | Fetch recent test results for a specific group and exam | | **Get recent results link exam** `classmarker_get_recent_results_link_exam` | Fetch recent exam results for a specific link and test combination | | **Get test details** `classmarker_get_test_details` | Retrieves detailed information for a specific test (exam) including its name and all assignment | | **Get user details** `classmarker_get_user_details` | Retrieve detailed information about a specific user | | **List categories** `classmarker_list_categories` | Retrieves all question categories organized in a hierarchical structure | | **List certificates** `classmarker_list_certificates` | List all certificates | | **List questions** `classmarker_list_questions` | Retrieve a paginated list of questions from your question bank | | **List recent results for groups** `classmarker_list_recent_results_for_groups` | Retrieve recent exam results for all groups in your ClassMarker account | | **List recent results for links** `classmarker_list_recent_results_for_links` | Retrieves recent test results from ALL links accessible to your API key | | **List users** `classmarker_list_users` | List all users | | **List webhooks** `classmarker_list_webhooks` | Retrieve all configured webhooks | | **Create access list item** `classmarker_create_access_list_item` | Add one or more access codes to an access list | | **Create category** `classmarker_create_category` | Create a new question category | | **Create group** `classmarker_create_group` | Create a new group | | **Create question** `classmarker_create_question` | Create a new question with specified text, type, and category in ClassMarker | | **Create user** `classmarker_create_user` | Create a new user in ClassMarker | | **Put category** `classmarker_put_category` | Update an existing sub-category | | **Put parent category** `classmarker_put_parent_category` | Update an existing parent category | | **Put question** `classmarker_put_question` | Updates an existing question in the ClassMarker question bank | ## Example prompts **Get Group Details** > Pull the relevant data from Classmarker, summarize it in plain English, and point out anything that needs attention. **Get Initial Finished After Timestamp** > Pull the relevant data from Classmarker, summarize it in plain English, and point out anything that needs attention. **Get Question** > Pull the relevant data from Classmarker, summarize it in plain English, and point out anything that needs attention. **Get Recent Results Group Exam** > Pull the relevant data from Classmarker, 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 OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Classmarker working from chat. | | Manual | ClawLink | |---|---|---| | **Credential handling** | Collect, validate, store, and rotate the Classmarker API key yourself, then make sure every tool call uses the right account. | Users complete the hosted ClawLink setup once and the connected Classmarker 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 Classmarker. | 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 Classmarker actions to the runtime in a format your agent can reliably use. | 28 tools for Classmarker are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Classmarker 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 Classmarker in the browser, and the 28 tools above work from chat. There is no SDK and no config file, and the Classmarker key you paste at setup is stored server-side rather than kept in your environment. Choosing between them?

Make sure Classmarker 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 Classmarker 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 Classmarker tools Classmarker 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 Classmarker 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. ### Classmarker 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 Classmarker has the right scopes or account access. A valid key can still be too limited for some reads or writes. ### Is there a OpenClaw Classmarker integration? Yes. ClawLink is the fastest way to connect OpenClaw to Classmarker: link your Classmarker account once in the browser and OpenClaw can call the Classmarker API through 28 ready-made tools — no custom code or token handling. ### How do I add Classmarker to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Classmarker skill from ClawHub, then you click Connect in the dashboard to authorize Classmarker. OpenClaw calls the tools from the next message — no config files, and the Classmarker key you paste is stored server-side instead of in your environment. ### How long does it take to connect Classmarker to OpenClaw? About two minutes. Sign in, click Connect next to Classmarker in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Classmarker 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 Classmarker working from chat. ### OpenClaw installed the Classmarker skill but can't call the tools The ClawHub skill teaches OpenClaw about Classmarker, but the calls run through the ClawLink plugin and your connected account. Make sure Classmarker 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 - [GitHub](https://claw-link.dev/openclaw/github) — Manage repositories, issues, pull requests, and workflows - [Connect PagerDuty](https://claw-link.dev/openclaw/pagerduty) — Manage incidents, on-call schedules, and services - [Connect SafetyCulture](https://claw-link.dev/openclaw/safetyculture) — SafetyCulture (formerly iAuditor) is a workplace operations platform that enables teams to conduct digital inspections, manage audits, track issues, schedule tasks, and maintain compliance through mobile and web applications.
