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 Passslot account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Passslot with - [OpenAI Agents SDK](https://composio.dev/toolkits/passslot/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/passslot/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/passslot/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/passslot/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/passslot/framework/codex) - [OpenClaw](https://composio.dev/toolkits/passslot/framework/openclaw) - [Hermes](https://composio.dev/toolkits/passslot/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/passslot/framework/google-adk) - [LangChain](https://composio.dev/toolkits/passslot/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/passslot/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/passslot/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/passslot/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/passslot/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/passslot/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/passslot/framework/autogen) ## TL;DR ### How Atomic Agent connects to Passslot 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 Passslot to Atomic Agent ### Connect Passslot 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 Passslot. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Passslot 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 Passslot MCP server, and what's possible with it? The Passslot MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Passslot account. It provides structured and secure access to your Apple Wallet passes, so your agent can retrieve, search, and organize passes, as well as discover available pass types on your behalf. - Comprehensive pass listing: Instantly fetch descriptions and details for all wallet passes you've created, allowing for easy review and management. - Filtered retrieval by pass type: Direct your agent to list passes filtered by a specific pass type, making it simple to track event tickets, coupons, or membership cards separately. - Pass type discovery: Have your agent retrieve all available pass type identifiers, helping you understand what categories and templates you can use for new passes. - Organized pass management: Let your agent sort, paginate, and organize your digital passes, so you can quickly find and manage exactly what you need. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `PASSSLOT_CREATE_SCANNER` | Create Scanner | Tool to create a new scanner in Passslot. Use when you need to create a PassVerifier or Browser type scanner. Your app key must have full access to manage scanners. If fullAccess is false, provide allowedTemplates array. | | `PASSSLOT_DELETE_SCANNER` | Delete Scanner | Tool to delete a scanner by ID. Use when you need to remove a scanner from the system. Requires full access app key to manage scanners. | | `PASSSLOT_GET_PASSES_BY_PASS_TYPE` | Get Passes by Pass Type | Tool to list Wallet passes, optionally filtered by a Pass Type ID. If passtype_id is provided, returns passes for that specific pass type. If passtype_id is not provided, returns all passes. | | `PASSSLOT_GET_PASS_TYPES` | Get Pass Types | Tool to list all available pass types. Use when you need to retrieve supported pass-type identifiers before creating passes. | | `PASSSLOT_GET_SCANNER` | Get Scanner | Tool to retrieve details of a specific scanner. Use when you need to get information about a scanner by its ID. Requires app key with full access to manage scanners. | | `PASSSLOT_LIST_SCANNERS` | List Scanners | Tool to retrieve a list of all scanners. Use when you need to list all configured scanners. Your app key must have full access to manage scanners. | | `PASSSLOT_LIST_TEMPLATES` | List Templates | Tool to retrieve a list of all pass templates. Use when you need to see available templates for creating passes. | | `PASSSLOT_UPDATE_SCANNER` | Update Scanner | Tool to update a scanner's configuration. Only name, fullAccess, and allowedTemplates can be updated. Use when you need to modify scanner permissions or rename a scanner. Your app key must have full access to manage scanners. | ## 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 Passslot from Atomic Agent With your account connected, ask Atomic Agent to work with Passslot in natural language. You can connect more apps through the same Composio integration as you need them.

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