This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Classmarker account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Classmarker with - [OpenAI Agents SDK](https://composio.dev/toolkits/classmarker/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/classmarker/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/classmarker/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/classmarker/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/classmarker/framework/codex) - [OpenClaw](https://composio.dev/toolkits/classmarker/framework/openclaw) - [Hermes](https://composio.dev/toolkits/classmarker/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/classmarker/framework/google-adk) - [LangChain](https://composio.dev/toolkits/classmarker/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/classmarker/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/classmarker/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/classmarker/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/classmarker/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/classmarker/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/classmarker/framework/autogen) ## TL;DR ### How Atomic Agent connects to Classmarker Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Classmarker to Atomic Agent ### Connect Classmarker to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Classmarker. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Classmarker account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Classmarker MCP server, and what's possible with it? The Classmarker MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Classmarker account. It provides structured and secure access to your quiz management tools, so your agent can create tests, manage users and groups, add questions, and control access codes—without manual intervention. - Automated user and group management: Let your agent create new users, add them to groups, or delete users and groups for streamlined participant organization. - Dynamic question and category creation: Instruct your agent to add new questions or categories to your exams, helping you build tests faster and keep content organized. - Access code and permissions control: Enable your agent to generate, assign, or delete access codes for specific exams, giving or revoking test access instantly as needed. - Test link and API key management: Allow your agent to manage test links or revoke API keys to maintain secure and up-to-date exam distribution. - Efficient data cleanup: Ask your agent to remove users, groups, test links, or access codes, keeping your Classmarker account tidy and up to date with minimal effort. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CLASSMARKER_CREATE_ACCESS_LIST_ITEM` | Create Access List Item | Tool to add one or more access codes to an access list. Use after obtaining a valid access_list_id to grant exam access. | | `CLASSMARKER_CREATE_CATEGORY` | Create a new question category | Tool to create a new question category. Use after confirming the parent category ID. | | `CLASSMARKER_CREATE_GROUP` | Create Group | Tool to create a new group. Use when you need to organize users into a specific group after planning your user structure. | | `CLASSMARKER_CREATE_QUESTION` | Create Question | Tool to create a new question with specified text, type, and category in ClassMarker. Supports multiplechoice, multipleresponse, truefalse, and essay question types. | | `CLASSMARKER_CREATE_USER` | Create ClassMarker User | Tool to create a new user in ClassMarker. Use after gathering user details to provision accounts. Provide user info and optional group assignments. Returns the complete API response. | | `CLASSMARKER_DELETE_ACCESS_LIST_ITEM` | Delete Access List Item | Removes one or more access codes from a ClassMarker access list. Access lists are used to control exam access by requiring users to provide unique identifiers (e.g., email addresses, employee IDs, student numbers). Each code can be used a limited number of times per exam, and codes are recorded with exam results. To use this action: 1. First call GET_ALL_GROUPS_LINKS_EXAMS to find available access list IDs 2. Provide the access_list_id and the list of codes to remove 3. Up to 100 codes can be removed per request Note: This action is idempotent - deleting codes that don't exist will not cause an error. | | `CLASSMARKER_DELETE_API_KEY` | Delete API Key | Tool to delete an API key by its ID. Use when you need to revoke an API key immediately. | | `CLASSMARKER_DELETE_GROUP` | Delete Group | Tool to delete a group by its ID. Use when you need to remove a group from ClassMarker. | | `CLASSMARKER_DELETE_TEST_LINK` | Delete Test Link | Deletes a specific link assignment from a test/exam in ClassMarker. Links are unique URLs that provide access to tests. This action is idempotent - deleting a non-existent link returns success. Use this when you need to remove a link from a test to revoke access via that specific URL. | | `CLASSMARKER_DELETE_USER` | Delete User | Tool to delete a specific user by ID. Use when you need to remove a user from ClassMarker after verifying the user's identity. | | `CLASSMARKER_DELETE_WEBHOOK` | Delete Webhook | Deletes a webhook listener from your ClassMarker account. This action removes a webhook configuration that was previously set up to receive real-time exam results. The ClassMarker API is idempotent - attempting to delete a non-existent webhook will return success without error. Webhook IDs are typically obtained from the ClassMarker web interface (My Account > Webhooks / API Keys) or through other webhook management tools if available. Note: This is a destructive operation and cannot be undone through the API. | | `CLASSMARKER_GET_GROUP_DETAILS` | Get Group Details | Retrieve detailed information about a specific group by ID. Returns group name and assigned tests. Note: This fetches all accessible groups and filters for the specified group_id, as ClassMarker API doesn't provide a direct single-group endpoint. | | `CLASSMARKER_GET_INITIAL_FINISHED_AFTER_TIMESTAMP` | Get Initial Finished After Timestamp | Compute the initial finishedAfterTimestamp for paginating ClassMarker test results. Use this action when you need to retrieve recent test results for the first time and don't have a previous 'next_finished_after_timestamp' value. This returns a Unix timestamp set to 2 weeks ago, which is the ClassMarker API's default starting point for result pagination. **When to use this:** - Starting a new pagination sequence for test results - You don't have a stored 'next_finished_after_timestamp' from a previous request **When NOT to use this:** - You have a 'next_finished_after_timestamp' from a previous response - use that value instead - For subsequent pagination requests - use the timestamp from the last successful response **Important:** ClassMarker API requires the finishedAfterTimestamp to be less than 3 months old. This action ensures compliance by setting it to 2 weeks ago. | | `CLASSMARKER_GET_QUESTION` | Get Question | Tool to retrieve a specific question by its ID. Use when you need detailed information of a question after confirming the question_id. | | `CLASSMARKER_GET_RECENT_RESULTS_GROUP_EXAM` | Get Recent Results For Group Exam | Tool to fetch recent test results for a specific group and exam. Use after determining a UNIX timestamp to retrieve only results finished after that time for the group and exam. | | `CLASSMARKER_GET_RECENT_RESULTS_LINK_EXAM` | Get Recent Results Link Exam | Fetch recent exam results for a specific link and test combination. Use CLASSMARKER_GET_ALL_GROUPS_LINKS_EXAMS first to obtain valid link_id and test_id values. This endpoint returns paginated results based on finishedAfterTimestamp for efficient incremental data retrieval. Supports up to 200 results per request. | | `CLASSMARKER_GET_TEST_DETAILS` | Get Test Details | Retrieves detailed information for a specific test (exam) including its name and all assignment contexts. Returns a list of groups and/or links where the test is assigned, with their IDs, names, and URL identifiers. Use when you need to find where a specific test is deployed or to get the complete deployment context for a test. Returns 'no_results' status if test ID doesn't exist. | | `CLASSMARKER_GET_USER_DETAILS` | Get User Details | Tool to retrieve detailed information about a specific user. Use after you have the user's ID and need the full user profile. | | `CLASSMARKER_LIST_CATEGORIES` | List Question Categories | Retrieves all question categories organized in a hierarchical structure. Returns parent categories with their nested sub-categories. Use this to browse available categories before creating questions or filtering content. | | `CLASSMARKER_LIST_CERTIFICATES` | List Certificates | Tool to list all certificates. Use when you need to retrieve all certificates available in the account. | | `CLASSMARKER_LIST_QUESTIONS` | List Questions | Retrieve a paginated list of questions from your question bank. Returns up to 200 questions per page. Use the optional 'page' parameter to navigate through multiple pages. Each question includes type, content, points, options, correct answers, and metadata. | | `CLASSMARKER_LIST_RECENT_RESULTS_FOR_GROUPS` | List Recent Results For Groups | Retrieve recent exam results for all groups in your ClassMarker account. Returns results from the last 2 weeks by default, or from a specified timestamp (must be within 3 months). Use this to fetch user performance data including scores, pass/fail status, and certificates. | | `CLASSMARKER_LIST_RECENT_RESULTS_FOR_LINKS` | List Recent Results for Links | Retrieves recent test results from ALL links accessible to your API key. Returns results completed after a specified timestamp (defaults to 2 weeks ago). Supports pagination for large result sets (max 200 per request). Use the next_finished_after_timestamp from the response for subsequent requests to fetch newer results without duplicates. Ideal for syncing or monitoring exam completions across all your test links. | | `CLASSMARKER_LIST_USERS` | List Users | Tool to list all users. Use when you need to retrieve every user in your account after confirming authentication. | | `CLASSMARKER_LIST_WEBHOOKS` | List Webhooks | Tool to retrieve all configured webhooks. Use when you need to programmatically list your webhook configurations. | | `CLASSMARKER_PUT_CATEGORY` | Update Sub-Category | Tool to update an existing sub-category. Use when you need to rename or move a sub-category after confirming its IDs. | | `CLASSMARKER_PUT_PARENT_CATEGORY` | Update an existing parent category | Tool to update an existing parent category. Use after confirming the parent category ID. | | `CLASSMARKER_PUT_QUESTION` | Update Question | Updates an existing question in the ClassMarker question bank. IMPORTANT CONSTRAINTS: - Cannot change the question_type of an existing question (must match original) - random_answers is only valid for multiplechoice and multipleresponse types - grade_style is only valid for multipleresponse type - options and correct_options are required for multiplechoice, multipleresponse, and truefalse - essay questions cannot have options, correct_options, or grade_style Set verify_only=True to validate changes without applying them. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Classmarker from Atomic Agent With your account connected, ask Atomic Agent to work with Classmarker in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Classmarker MCP server, the agents and LLMs can only access a fixed set of Classmarker tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Classmarker and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Classmarker tools. ### Can I manage the permissions and scopes for Classmarker while using Tool Router? Yes, absolutely. You can configure which Classmarker scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Classmarker data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
