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 ClickHouse account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate ClickHouse with - [ChatGPT](https://composio.dev/toolkits/clickhouse/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/clickhouse/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/clickhouse/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/clickhouse/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/clickhouse/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/clickhouse/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/clickhouse/framework/codex) - [Grok Build](https://composio.dev/toolkits/clickhouse/framework/grok-build) - [Cursor](https://composio.dev/toolkits/clickhouse/framework/cursor) - [VS Code](https://composio.dev/toolkits/clickhouse/framework/vscode) - [OpenCode](https://composio.dev/toolkits/clickhouse/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/clickhouse/framework/openclaw) - [Hermes](https://composio.dev/toolkits/clickhouse/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/clickhouse/framework/google-adk) - [LangChain](https://composio.dev/toolkits/clickhouse/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/clickhouse/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/clickhouse/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/clickhouse/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/clickhouse/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/clickhouse/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/clickhouse/framework/autogen) ## TL;DR ### How Atomic Agent connects to ClickHouse 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 ClickHouse to Atomic Agent ### Connect ClickHouse 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 ClickHouse. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your ClickHouse 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 ClickHouse MCP server, and what's possible with it? The ClickHouse MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your ClickHouse account. It provides structured and secure access so your agent can perform ClickHouse operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CLICKHOUSE_EXECUTE_QUERY` | Execute ClickHouse Query | Execute a SQL query in ClickHouse and return the results. This is the primary action for querying data from ClickHouse databases. | | `CLICKHOUSE_GET_DATABASE_SCHEMA` | Get Database Schema | Get comprehensive schema overview of an entire database including all tables and optionally their column definitions. Essential for AI agents to understand the complete database structure in a single call. | | `CLICKHOUSE_GET_PLAY_INTERFACE` | Get ClickHouse Play Interface | Get the ClickHouse Play web user interface for interactive query execution. Returns HTML page with Monaco Editor for writing queries and visualizing results. | | `CLICKHOUSE_GET_TABLE_SCHEMA` | Get Table Schema | Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. This is essential for AI agents to understand table structure before constructing queries. | | `CLICKHOUSE_LIST_DATABASES` | List ClickHouse Databases | List all databases in the ClickHouse instance. Useful for discovering available databases before querying tables. | | `CLICKHOUSE_LIST_TABLES` | List ClickHouse Tables | List tables in ClickHouse databases. Returns information about tables including their engine, size, and row count. | ## 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 ClickHouse from Atomic Agent With your account connected, ask Atomic Agent to work with ClickHouse in natural language. You can connect more apps through the same Composio integration as you need them.

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