+# Google Cloud BigQuery
+
+Cursor plugin that connects agents to [Google Cloud BigQuery](https://docs.cloud.google.com/bigquery/docs/use-bigquery-mcp) through Google Cloud BigQuery's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Explore datasets and tables and run SQL queries.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Google Cloud BigQuery**.
+3. Click **Install**, then complete the Google Cloud BigQuery sign-in prompt.
+
+Or run `/add-plugin google-cloud-bigquery` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "google-cloud-bigquery": {
+      "type": "http",
+      "url": "https://bigquery.googleapis.com/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth. Cursor prompts for Google Cloud BigQuery sign-in when the plugin connects — there is no client ID or personal access token to configure.
+
+## Before you connect
+
+You need a Google Cloud project with the BigQuery API enabled, and your Google account needs the MCP Tool User role (`roles/mcp.toolUser`) plus BigQuery Job User and Data Viewer on that project.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Explore | List datasets and tables and read their metadata and schemas |
+| Query | Run read-only SQL, including BigQuery ML functions |
+| Write | Run DML and DDL when the account allows it |
+| Jobs | Poll results and cancel running query jobs |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- Queries are billed to the project id passed to the tool.
+- Admins can block the write-capable `execute_sql` tool with an IAM deny policy while leaving read-only queries available.
+- Grok also offers this connector with service-identity auth; this plugin configures only the user OAuth flow.
+
+## Docs
+
+- Use the BigQuery MCP server: https://docs.cloud.google.com/bigquery/docs/use-bigquery-mcp
+- Tools reference: https://docs.cloud.google.com/bigquery/docs/reference/mcp
+- Server URL: https://bigquery.googleapis.com/mcp
