How to Use BigQuery MCP Server

BigQuery MCP Server represents a significant advancement in how developers interact with their data. This innovative tool functions as an intelligent bridge between AI assistants like Claude and your BigQuery datasets, enabling natural language interactions with complex database structures. By implementing the Model Context Protocol (MCP), BigQuery MCP Server eliminates the traditional barriers between AI models and data storage systems.

At its core, BigQuery MCP Server transforms how you access and analyze data by allowing you to query your BigQuery datasets through conversational language rather than writing SQL statements manually. This capability dramatically reduces the technical expertise required to extract insights from your data and accelerates the data exploration process. Consider this typical interaction:

You: "What were our top 10 customers by revenue last quarter?"
Claude: *queries your BigQuery database and presents formatted results with analysis*

The server supports a comprehensive range of capabilities that make data interaction more intuitive:

Setting Up BigQuery MCP Server for Seamless AI Data Integration

Implementing BigQuery MCP Server requires minimal configuration while providing significant benefits for data analysis and API development. The setup process follows a straightforward path that can be completed in minutes, enabling you to quickly begin interacting with your data through natural language.

Prerequisites for BigQuery MCP Server Installation

Before beginning the installation process, ensure you have:

Installation Options for BigQuery MCP Server

The installation process offers two approaches to accommodate different user preferences and requirements:

Option 1: Quick Installation via Smithery (Recommended)

For most users, the Smithery method provides the simplest path to implementation:

npx @smithery/cli install @ergut/mcp-bigquery-server --client claude

During this streamlined installation process, you'll be prompted for:

Once configured, Smithery automatically updates your Claude Desktop configuration and restarts the application, creating a seamless setup experience.

Option 2: Manual Configuration

For users requiring more control over the installation process:

Authenticate with Google Cloud using one of these methods:

For development environments:

gcloud auth application-default login

For production environments:

# Use a service account key file with the --key-file parameter

Configure Claude Desktop by adding to your claude_desktop_config.json:

{
"mcpServers": {
 "bigquery": {
   "command": "npx",
   "args": [
     "-y",
     "@ergut/mcp-bigquery-server",
     "--project-id",
     "your-project-id",
     "--location",
     "us-central1"
   ]
 }
}
}

When using a service account, include the --key-file parameter pointing to your key file location.

Permissions and Security Considerations

BigQuery MCP Server requires specific permissions to function correctly while maintaining data security:

These permission sets ensure the server can read data and execute queries while preventing any modifications to your datasets. This read-only approach maintains data integrity while still enabling comprehensive analysis capabilities.

For production environments, consider these additional security practices:

Once configured, verify your installation by asking Claude a simple question about your data, such as "What tables are available in my BigQuery project?" The system should respond with an accurate list of tables from your project, confirming successful implementation.

Enhancing API Development with Apidog MCP Server Integration

While BigQuery MCP Server focuses on database interactions, Apidog MCP Server takes a different approach by connecting your API specifications directly to AI-powered IDEs. This integration enables AI assistants to understand your API structure, accelerating development and improving code quality through context-aware assistance.

Apidog MCP Server allows developers to leverage AI assistants for generating or modifying code based on API specifications, searching through specification content, and performing various development tasks with a deep understanding of your API structure. This capability transforms how developers interact with their APIs, making development more efficient and reducing the learning curve for complex API structures.

The server works by reading and caching API specification data on your local machine, making it available to AI assistants through a standardized interface. Developers can then instruct the AI on specific tasks related to their API specifications, such as generating code for specific endpoints, updating DTOs based on schema changes, adding documentation comments, or creating MVC code structures.

Setting up Apidog MCP Server requires Node.js (version 18 or higher) and an IDE that supports MCP, such as Cursor or VS Code with the Cline plugin. The server supports three different data sources:

  1. Apidog projects
  2. Online API documentation published by Apidog
  3. Swagger/OpenAPI files

For Apidog project integration, you'll need to obtain an API access token and your project ID.

creating API access token at Apidog
obtaining project ID at Apidog

With these credentials, you can configure your MCP-compatible IDE to connect to your Apidog project.

In Cursor, for example, you would add a configuration like:

{
  "mcpServers": {
    "API specification": {
      "command": "npx",
      "args": [
        "-y",
        "apidog-mcp-server@latest",
        "--project=<project-id>"
      ],
      "env": {
        "APIDOG_ACCESS_TOKEN": "<access-token>"
      }
    }
  }
}

This configuration enables your AI assistant to access and understand your API specifications, allowing for more intelligent code generation and assistance.

Streamlining Development Workflows with Apidog MCP for API Specifications

Apidog MCP Server significantly enhances development workflows by providing AI assistants with comprehensive knowledge of your API specifications. This integration enables developers to work more efficiently, with the AI understanding the structure, endpoints, parameters, and schemas defined in your API.

When working with Apidog MCP Server , developers can simply instruct the AI to perform tasks related to their API specifications. For example, you might ask the AI to:

The AI assistant, with access to your API specifications through the MCP server, can then generate accurate, context-aware code that aligns perfectly with your API structure. This eliminates the need to constantly reference documentation or switch between tools when implementing API-related functionality.

Conclusion

The integration of MCP servers into development workflows represents a significant advancement in how developers interact with data and API specifications. BigQuery MCP Server enables natural language interactions with database systems, while Apidog MCP Server transforms API development by connecting specifications directly to AI assistants.
