+title: Model Context Protocol (MCP)
+---
+
+Connect AI assistants to Bytebase using the Model Context Protocol.
+
+## Prerequisites
+
+- [Configure external URL](/get-started/self-host/external-url) if you haven't already.
+
+- OAuth authentication is required on first connection. Ensure you have appropriate Bytebase permissions.
+
+## Setup
+
+Navigate to **Integration** > **MCP** in your Bytebase console. Choose one of the following options:
+
+### Option 1: JSON Configuration
+
+Add this JSON to your MCP client configuration file:
+
+```json
+{
+  "mcpServers": {
+    "bytebase": {
+      "type": "http",
+      "url": "{https://your-bytebase-url.com}/mcp"
+    }
+  }
+}
+```
+
+### Option 2: CLI Commands
+
+Alternatively, use the CLI command shown on the MCP integration page for your preferred tool (Claude Code, Codex, Copilot CLI, Gemini CLI, or VS Code).
+
+## Usage
+
+Once connected, try asking your AI assistant:
+
+- "List all projects in my Bytebase instance"
+- "Show me the schema for database X"
+- "Generate a migration script to add a users table"
