## Description
BigQuery database integration with schema inspection and query capabilities

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "mcp-server-bigquery": {
    "command": "npx",
    "args": ["-y","@smithery/cli"],
    "env": {
      "BIGQUERY_PROJECT": "",
      "BIGQUERY_LOCATION": "",
      "BIGQUERY_DATASETS": "",
      "BIGQUERY_KEY_FILE": "",
      "BIGQUERY_TIMEOUT": ""
    }
  }
}
```

**Requires environment variables:** `BIGQUERY_PROJECT`, `BIGQUERY_LOCATION`, `BIGQUERY_DATASETS`, `BIGQUERY_KEY_FILE`, `BIGQUERY_TIMEOUT` — the values above are empty placeholders; fill in real credentials before running (see the repository for what each one is for).

# BigQuery MCP server

[![smithery badge](https://smithery.ai/badge/mcp-server-bigquery)](https://smithery.ai/server/mcp-server-bigquery)

A Model Context Protocol server that provides access to BigQuery. This server enables LLMs to inspect database schemas and execute queries.

## Components

### Tools

The server implements one tool:

- `execute-query`: Executes a SQL query using BigQuery dialect
- `list-tables`: Lists all tables in the BigQuery database
- `describe-table`: Describes the schema of a specific table

## Configuration

The server can be configured either with command line arguments or environment variables.

| Argument     | Environment Variable | Required | Description                                                                                                                                                                                                                                                                                                                                                    |
| ------------ | -------------------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `--project`  | `BIGQUERY_PROJECT`   | Yes      | The GCP project ID.                                                                                                                                                                                                                                                                                                                                            |

| `--dataset`  | `BIGQUERY_DATASETS`  | No       | Only take specific BigQuery datasets into consideration. Several datasets can be specified by repeating the argument (e.g. `--dataset my_dataset_1 --dataset my_dataset_2`) or by joining them with a comma in the environment variable (e.g. `BIGQUERY_DATASETS=my_dataset_1,my_dataset_2`). If not provided, all datasets in the project will be considered. |
| `--key-file` | `BIGQUERY_KEY_FILE`  | No       | Path to a service account key file for BigQuery.

```

### Claude Desktop

On MacOS: `~/Library/Application\ Support/Claude/claude_desktop_config.json`  
On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "bigquery": {
      "command": "uvx",
      "args": ["mcp-server-bigquery"],
      "env": {
        "BIGQUERY_PROJECT": "{{GCP_PROJECT_ID}}",
        "BIGQUERY_LOCATION": "{{GCP_LOCATION}}"
      }
    }
  }
}
```

## Cursor

1. Open Cursor Settings → MCP
2. Click Add new global MCP server
3. Add an entry for the BigQuery MCP, following the pattern below:

```json
{
  "mcpServers": {
    "bigquery": {
      "command": "uvx",
      "args": ["mcp-server-bigquery"],
      "env": {
        "BIGQUERY_PROJECT": "{{GCP_PROJECT_ID}}",
        "BIGQUERY_LOCATION": "{{GCP_LOCATION}}"
      }
    }
  }
}
```
