It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity. In this guide, I will explain the easiest and most secure way to connect your Gumroad account to Antigravity IDE via Composio Connect, so it can show all sales from the past week, list active subscriptions for your e-book, get your Gumroad profile details, and more without ever putting your account credentials at risk. ## Also integrate Gumroad with - [ChatGPT](https://composio.dev/toolkits/gumroad/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/gumroad/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/gumroad/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/gumroad/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/gumroad/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/gumroad/framework/codex) - [Cursor](https://composio.dev/toolkits/gumroad/framework/cursor) - [VS Code](https://composio.dev/toolkits/gumroad/framework/vscode) - [OpenCode](https://composio.dev/toolkits/gumroad/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/gumroad/framework/openclaw) - [Hermes](https://composio.dev/toolkits/gumroad/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/gumroad/framework/cli) - [Google ADK](https://composio.dev/toolkits/gumroad/framework/google-adk) - [LangChain](https://composio.dev/toolkits/gumroad/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/gumroad/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/gumroad/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/gumroad/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/gumroad/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Gumroad to Antigravity ### Connect Gumroad to Antigravity Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute. ### 1. Open the MCP Config Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor. ### 2. Get your API key Go to the [Composio Dashboard](https://dashboard.composio.dev/~/org/connect/clients/) and copy your API key. ### 3. Add Composio to mcp_config.json Paste the following configuration into the file: ```bash { "mcpServers": { "remote-composio": { "serverUrl": "https://connect.composio.dev/mcp", "headers": { "x-consumer-api-key": "your-composio-api-key" } } } } ``` ## What is the Gumroad MCP server, and what's possible with it? The Gumroad MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gumroad account. It provides structured and secure access to your Gumroad business data, so your agent can review sales, manage subscriptions, handle webhook resources, and retrieve user profile details on your behalf. - Sales data insights: Instantly pull reports on all successful sales, with options to filter by date, product, or customer email for real-time business tracking. - Subscription management: Let your agent list, review, and manage all active resource subscriptions, making it easy to keep tabs on recurring customers and memberships. - User profile retrieval: Fetch up-to-date profile details for your Gumroad account, giving your agent context for personalized actions or reporting. - Webhook automation: Subscribe or unsubscribe from Gumroad resources to receive real-time event notifications, enabling seamless integration with your automation workflows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `GUMROAD_GET_RESOURCE_SUBSCRIPTIONS` | Get Resource Subscriptions | Tool to show all active subscriptions of the user for the input resource. Use when you need to review existing webhooks before adding a new one. | | `GUMROAD_GET_SALES` | Get Sales | Tool to retrieve all successful sales by the authenticated user; excludes failed charges, abandoned carts, and page views — conversion rates cannot be derived from this data. Use when you need to list your Gumroad sales, optionally filtering by email, date range, product, or pagination. For high sales volumes, combine product_id and/or after/before filters with page to avoid large unfiltered result sets. | | `GUMROAD_GET_USER` | Get User | Tool to retrieve the authenticated user's data. Use when you need the current user's profile details after authentication. | | `GUMROAD_LIST_PRODUCTS` | List Products | Tool to retrieve all products for the authenticated Gumroad account. Use when you need product IDs for downstream operations like license verification, subscriber retrieval, or offer-code management. | | `GUMROAD_SUBSCRIBE_TO_RESOURCE` | Subscribe to Resource | Tool to subscribe to a resource. Use when you need to receive real-time event webhooks after creating your webhook endpoint. | | `GUMROAD_UNSUBSCRIBE_FROM_RESOURCE` | Unsubscribe From Resource | Tool to unsubscribe from a resource. Use after verifying the subscription ID exists to remove webhook. | | `GUMROAD_VERIFY_LICENSE` | Verify License | Tool to verify a Gumroad license key against a specific product. Use when you need to check if a license key is valid, check usage count, or verify membership entitlement for software licensing or gated content. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Gumroad MCP server via Composio to run actions that you authorize directly from the agent panel. ## Complete Code None listed. ## Conclusion ### Conclusion You have successfully connected Gumroad to Antigravity using Composio Connect. Your agent can now use Gumroad securely without exposing credentials in prompts or local scripts. ## How to build Gumroad MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/gumroad/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/gumroad/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/gumroad/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/gumroad/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/gumroad/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/gumroad/framework/codex) - [Cursor](https://composio.dev/toolkits/gumroad/framework/cursor) - [VS Code](https://composio.dev/toolkits/gumroad/framework/vscode) - [OpenCode](https://composio.dev/toolkits/gumroad/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/gumroad/framework/openclaw) - [Hermes](https://composio.dev/toolkits/gumroad/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/gumroad/framework/cli) - [Google ADK](https://composio.dev/toolkits/gumroad/framework/google-adk) - [LangChain](https://composio.dev/toolkits/gumroad/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/gumroad/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/gumroad/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/gumroad/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/gumroad/framework/crew-ai) ## Related Toolkits - [Addresszen](https://composio.dev/toolkits/addresszen) - Addresszen is a real-time address autocomplete and verification service.

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