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 Linkup account to Antigravity IDE via Composio Connect, so it can find recent articles on quantum computing breakthroughs, summarize top news about generative AI today, get sourced answer about electric vehicle market trends, and more without ever putting your account credentials at risk. ## Also integrate Linkup with - [ChatGPT](https://composio.dev/toolkits/linkup/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/linkup/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/linkup/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/linkup/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/linkup/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/linkup/framework/codex) - [Cursor](https://composio.dev/toolkits/linkup/framework/cursor) - [VS Code](https://composio.dev/toolkits/linkup/framework/vscode) - [OpenCode](https://composio.dev/toolkits/linkup/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/linkup/framework/openclaw) - [Hermes](https://composio.dev/toolkits/linkup/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/linkup/framework/cli) - [Google ADK](https://composio.dev/toolkits/linkup/framework/google-adk) - [LangChain](https://composio.dev/toolkits/linkup/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/linkup/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/linkup/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/linkup/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/linkup/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 Linkup to Antigravity ### Connect Linkup 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 Linkup MCP server, and what's possible with it? The Linkup MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linkup account. It provides structured and secure access to enterprise-grade web search and natural language answering, so your agent can perform actions like retrieving relevant information, answering questions, summarizing sources, and surfacing insights from the web on your behalf. - Natural language question answering: Ask your agent complex or open-ended questions and get concise, sourced natural language answers pulled from web data. - Structured web search and insights retrieval: Let your agent perform deep searches on any topic and return structured insights, detailed summaries, or raw search results as needed. - Source-backed information synthesis: Get responses that include not just answers but citations to the original web sources, making it easy to verify and explore further. - Customizable search depth and output: Have the agent adjust search precision, control answer format (summary, structured, or detailed search results), and even include images if your use case needs them. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LINKUP_CREATE_RESPONSE` | Create Response | Proxy endpoint for OpenAI-compatible response generation. Used when the OpenAI client's base URL is set to Linkup. Supports 'linkup-standard' for faster results and 'linkup-deep' for more comprehensive results. | | `LINKUP_FETCH_WEBPAGE` | Fetch Webpage | Fetch and retrieve a markdown representation of a webpage from a given URL. Supports optional JavaScript rendering for single-page applications, raw HTML extraction, and image extraction from the webpage content. Use this when you need to extract clean, structured content from web pages. | | `LINKUP_GET_CREDITS_BALANCE` | Get Credits Balance | Tool to retrieve the current credits balance for your Linkup account. Returns the number of credits remaining that can be used for search and fetch operations. | | `LINKUP_SEARCH` | Search Linkup | Search the web and retrieve insights using Linkup's API. This action provides three output modes: natural language answers with sources (sourcedAnswer), raw search context (searchResults), or custom structured JSON (structured). Supports filtering by date range and domains, with optional image results. Standard depth uses 1 credit, deep search uses 10 credits. Only indexes publicly available web content; private repositories and internal endpoints return no results. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Linkup 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 Linkup to Antigravity using Composio Connect.

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