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 Memberstack account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Memberstack with - [OpenAI Agents SDK](https://composio.dev/toolkits/memberstack/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/memberstack/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/memberstack/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/memberstack/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/memberstack/framework/codex) - [OpenClaw](https://composio.dev/toolkits/memberstack/framework/openclaw) - [Hermes](https://composio.dev/toolkits/memberstack/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/memberstack/framework/google-adk) - [LangChain](https://composio.dev/toolkits/memberstack/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/memberstack/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/memberstack/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/memberstack/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/memberstack/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/memberstack/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/memberstack/framework/autogen) ## TL;DR ### How Atomic Agent connects to Memberstack 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 Memberstack to Atomic Agent ### Connect Memberstack 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 Memberstack. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Memberstack 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 Memberstack MCP server, and what's possible with it? The Memberstack MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Memberstack account. It provides structured and secure access to your member management system, so your agent can perform actions like creating members, updating profiles, managing plans, and retrieving membership data on your behalf. - Automated member creation and onboarding: Instantly add new users to your platform with customizable fields, plans, and metadata—no manual input needed. - Profile updates and member management: Let your agent update member details, modify custom fields, or change emails and metadata as your users grow or their needs change. - Membership plan handling: Effortlessly list available plans, assign plans to members, or remove free plans when subscriptions change. - Member lookup and insights: Retrieve individual member profiles by ID or email, or fetch a paginated list of all your members for deeper analysis and automation. - Secure member deletion: Ensure compliance and data hygiene by directing your agent to safely delete members who no longer require access. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `MEMBERSTACK_CREATE_MEMBER` | Create Member | Tool to create a new member in your application. Use after gathering email, password, optional plans, custom fields, metadata, and redirect. | | `MEMBERSTACK_DELETE_MEMBER` | Delete Member | Tool to permanently delete a member from your application. Use after confirming you no longer need the member's data and have the member ID. | | `MEMBERSTACK_GET_MEMBER` | Get Member | Tool to retrieve a specific member by ID or email. Use when you need to fetch member profile details for a given identifier (ID or email). Example: "Get member mem_sb_12345". | | `MEMBERSTACK_LIST_DATA_TABLES` | List Data Tables | Tool to retrieve all data tables in your Memberstack application. Returns table metadata including keys, field definitions, and access control rules. | | `MEMBERSTACK_LIST_MEMBERS` | List Members | Tool to retrieve a paginated list of all members in your application. Use when you need to iterate through members with cursor-based pagination. | | `MEMBERSTACK_LIST_PLANS` | List Plans | Tool to list all available membership plans. Use when you need to retrieve plan IDs and details before assigning or comparing plans. | | `MEMBERSTACK_REMOVE_FREE_PLAN` | Remove Free Plan | Tool to remove a free plan from an existing member. Use after confirming the member's subscription status. Example: "Remove free plan pln_sb_67890 from member mem_sb_12345". | | `MEMBERSTACK_UPDATE_MEMBER` | Update Member | Tool to update an existing member's information. Use when you have a member ID and need to modify their email, customFields, metaData, JSON data, or loginRedirect. | ## 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 Memberstack from Atomic Agent With your account connected, ask Atomic Agent to work with Memberstack in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Memberstack MCP server, the agents and LLMs can only access a fixed set of Memberstack tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Memberstack 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 Memberstack tools. ### Can I manage the permissions and scopes for Memberstack while using Tool Router? Yes, absolutely. You can configure which Memberstack 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 Memberstack data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
