With its recent AI makeover, it can do more than just help you write code. You can connect your applications to it and let LLMs automate many of the mundane tasks in your workflow. In this guide, I will explain how to connect ClickHouse with VS Code in the most secure and robust way possible via Composio. ## Also integrate ClickHouse with - [ChatGPT](https://composio.dev/toolkits/clickhouse/framework/chatgpt) - [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) - [Cursor](https://composio.dev/toolkits/clickhouse/framework/cursor) - [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) - [CLI](https://composio.dev/toolkits/clickhouse/framework/cli) - [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) ## 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 its 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 ClickHouse to VS Code ### Integrate ClickHouse MCP with VS Code ### 1. Install with one click Click the button below to add Composio to VS Code. You will be prompted to authorize. This requires VS Code 1.99+ with GitHub Copilot. [+Install in VS Code](vscode:mcp/install?%7B%22name%22%3A%22composio%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fconnect.composio.dev%2Fmcp%22%7D) ### 2. Or add manually Open or create .vscode/mcp.json in your project root and add the following configuration: ```bash { "servers": { "composio": { "type": "http", "url": "https://connect.composio.dev/mcp" } } } ``` ## 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_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. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, VS Code can access the ClickHouse MCP server via Composio to run the app actions you authorize, directly from your coding workflow. ## Complete Code None listed. ## Conclusion ### Way Forward Now that ClickHouse is connected, extend your setup by connecting the other apps you already use every day, so your agent can run true cross-app workflows end to end. - Connect Calendar to turn threads into scheduled meetings automatically. - Connect Slack or Teams to post summaries, approvals, and alerts where your team works. - Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs. - Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps. - Connect HubSpot or Salesforce to log customer context, update records, and draft follow-ups. Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation. ## How to build ClickHouse MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/clickhouse/framework/chatgpt) - [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) - [Cursor](https://composio.dev/toolkits/clickhouse/framework/cursor) - [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) - [CLI](https://composio.dev/toolkits/clickhouse/framework/cli) - [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) ## Related Toolkits - [Firecrawl](https://composio.dev/toolkits/firecrawl) - Firecrawl automates large-scale web crawling and data extraction.

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 VS Code? Yes, you can. VS Code 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) · [Composio docs](https://docs.composio.dev/llms.txt)
