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 Linkup account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Linkup with - [ChatGPT](https://composio.dev/toolkits/linkup/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/linkup/framework/antigravity) - [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) - [Grok Build](https://composio.dev/toolkits/linkup/framework/grok-build) - [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) - [Pi](https://composio.dev/toolkits/linkup/framework/pi-agent) - [DeepSeek Harness](https://composio.dev/toolkits/linkup/framework/deepseek) - [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) - [Pydantic AI](https://composio.dev/toolkits/linkup/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/linkup/framework/autogen) ## TL;DR ### How Atomic Agent connects to Linkup 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 Linkup to Atomic Agent ### Connect Linkup 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 Linkup. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Linkup 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 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. ## 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 Linkup from Atomic Agent With your account connected, ask Atomic Agent to work with Linkup in natural language. You can connect more apps through the same Composio integration as you need them.

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 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 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)
