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 Coinmarketcal account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Coinmarketcal with - [OpenAI Agents SDK](https://composio.dev/toolkits/coinmarketcal/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/coinmarketcal/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/coinmarketcal/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/coinmarketcal/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/coinmarketcal/framework/codex) - [OpenClaw](https://composio.dev/toolkits/coinmarketcal/framework/openclaw) - [Hermes](https://composio.dev/toolkits/coinmarketcal/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/coinmarketcal/framework/google-adk) - [LangChain](https://composio.dev/toolkits/coinmarketcal/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/coinmarketcal/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/coinmarketcal/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/coinmarketcal/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/coinmarketcal/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/coinmarketcal/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/coinmarketcal/framework/autogen) ## TL;DR ### How Atomic Agent connects to Coinmarketcal 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 Coinmarketcal to Atomic Agent ### Connect Coinmarketcal 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 Coinmarketcal. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Coinmarketcal 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 Coinmarketcal MCP server, and what's possible with it? The Coinmarketcal MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coinmarketcal account. It provides structured and secure access to the Coinmarketcal crypto events calendar, so your agent can perform actions like fetching upcoming cryptocurrency events, discovering new project launches, and tracking market-impacting announcements on your behalf. - Fetch upcoming crypto events: Ask your agent to retrieve a list of scheduled events, announcements, or coin releases that could impact the crypto markets. - Discover project launches and updates: Stay on top of new token launches, hard forks, or upgrade announcements directly from Coinmarketcal’s trusted community-driven calendar. - Track market-impacting news: Let your agent monitor important developments and milestone events for specific coins or across the entire crypto ecosystem. - Stay informed on trending events: Quickly surface the most anticipated or discussed crypto events, enabling smarter trading and investment decisions. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `COINMARKETCAL_LIST_COINS` | List Coins | Tool to retrieve list of all available coins/cryptocurrencies in CoinMarketCal database. Use when you need to fetch coin information including IDs, names, symbols, and event counts. | | `COINMARKETCAL_LIST_EVENT_CATEGORIES` | List Event Categories | Tool to list all event categories. Use when you need to fetch available event categories. | | `COINMARKETCAL_LIST_EVENTS` | List Cryptocurrency Events | Tool to retrieve list of cryptocurrency events. Use when you need to fetch upcoming or past crypto events filtered by date range, coins, categories, or other criteria. Note: Cannot retrieve events before 25/11/2017. The can_occur_before field is important as some events may happen before their stated date. | ## 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 Coinmarketcal from Atomic Agent With your account connected, ask Atomic Agent to work with Coinmarketcal in natural language. You can connect more apps through the same Composio integration as you need them.

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