Building and Running

Build the project:

npm run build

Run the server:

# Start local server (direct MCP communication)
npx dataforseo-mcp-server

# Start HTTP server
npx dataforseo-mcp-server http

HTTP Server Configuration

The server runs on port 3000 by default and supports both Basic Authentication and environment variable-based authentication.

To start the HTTP server, run:

npm run http

Authentication Methods

1. Basic Authentication

   • Send requests with Basic Auth header:

   Authorization: Basic <base64-encoded-credentials>

   • Credentials format: username:password

2. Environment Variables

   • If no Basic Auth is provided, the server will use credentials from environment variables:

   export DATAFORSEO_USERNAME=your_username
   export DATAFORSEO_PASSWORD=your_password

Cloudflare Worker Deployment

The DataForSEO MCP Server can be deployed as a Cloudflare Worker for serverless, edge-distributed access to DataForSEO APIs.

Worker Features

• Edge Distribution: Deploy globally across Cloudflare's edge network

• Serverless: No server management required

• Auto-scaling: Handles traffic spikes automatically

• MCP Protocol Support: Compatible with both Streamable HTTP and SSE transports

• Environment Variables: Secure credential management through Cloudflare dashboard

Quick Start

1. Install Wrangler CLI:

   npm install -g wrangler

2. Configure Worker:

   # Login to Cloudflare
   wrangler login
   
   # Set environment variables
   wrangler secret put DATAFORSEO_USERNAME
   wrangler secret put DATAFORSEO_PASSWORD

3. Deploy Worker:

   # Build and deploy
   npm run build
   wrangler deploy --main build/index-worker.js

Implementation Options

You can either:

1. Add a new tool to an existing module

2. Create a completely new module

Adding a New Tool

Here's how to add a new tool to any new or pre-existing module:

// src/code/modules/your-module/tools/your-tool.tool.ts
import { BaseTool } from '../../base.tool';
import { DataForSEOClient } from '../../../client/dataforseo.client';
import { z } from 'zod';

export class YourTool extends BaseTool {
  constructor(private client: DataForSEOClient) {
    super(client);
    // DataForSEO API returns extensive data with many fields, which can be overwhelming
    // for AI agents to process. We select only the most relevant fields to ensure
    // efficient and focused responses.
    this.fields = [
      'title',           // Example: Include the title field
      'description',     // Example: Include the description field
      'url',            // Example: Include the URL field
      // Add more fields as needed
    ];
  }

  getName() {
    return 'your-tool-name';
  }

  getDescription() {
    return 'Description of what your tool does';
  }

  getParams(): z.ZodRawShape {
    return {
      // Required parameters
      keyword: z.string().describe('The keyword to search for'),
      location: z.string().describe('Location in format "City,Region,Country" or just "Country"'),
      
      // Optional parameters
      fields: z.array(z.string()).optional().describe('Specific fields to return in the response. If not specified, all fields will be returned'),
      language: z.string().optional().describe('Language code (e.g., "en")'),
    };
  }

  async handle(params: any) {
    try {
      // Make the API call
      const response = await this.client.makeRequest({
        endpoint: '/v3/dataforseo_endpoint_path',
        method: 'POST',
        body: [{
          // Your request parameters
          keyword: params.keyword,
          location: params.location,
          language: params.language,
        }],
      });

      // Validate the response for errors
      this.validateResponse(response);

      //if the main data array is specified in tasks[0].result[:] field
      const result = this.handleDirectResult(response);
      //if main data array specified in tasks[0].result[0].items field
      const result = this.handleItemsResult(response);
      // Format and return the response
      return this.formatResponse(result);
    } catch (error) {
      // Handle and format any errors
      return this.formatErrorResponse(error);
    }
  }
}

Creating a New Module

1. Create a new directory under src/core/modules/ for your module:

mkdir -p src/core/modules/your-module-name

2. Create module files:

// src/core/modules/your-module-name/your-module-name.module.ts
import { BaseModule } from '../base.module';
import { DataForSEOClient } from '../../client/dataforseo.client';
import { YourTool } from './tools/your-tool.tool';

export class YourModuleNameModule extends BaseModule {
  constructor(private client: DataForSEOClient) {
    super();
  }

  getTools() {
    return {
      'your-tool-name': new YourTool(this.client),
    };
  }
}

3. Register your module in src/core/config/modules.config.ts:

export const AVAILABLE_MODULES = [
  'SERP',
  'KEYWORDS_DATA',
  'ONPAGE',
  'DATAFORSEO_LABS',
  'BACKLINKS',
  'BUSINESS_DATA',
  'DOMAIN_ANALYTICS',
  'CONTENT_ANALYSIS',
  'YOUR_MODULE_NAME'  // Add your module name here
] as const;

4. Initialize your module in src/main/index.ts:

if (isModuleEnabled('YOUR_MODULE_NAME', enabledModules)) {
  modules.push(new YourModuleNameModule(dataForSEOClient));
}

Field Configuration

The MCP server supports field filtering to customize which data fields are returned in API responses. This helps reduce response size and focus on the most relevant data for your use case.

Configuration File Format

Create a JSON configuration file with the following structure:

{
  "supported_fields": {
    "tool_name": ["field1", "field2", "field3"],
    "another_tool": ["field1", "field2"]
  }
}

Using Field Configuration

Pass the configuration file using the --configuration parameter:

# With npm
npm run cli -- http --configuration field-config.json

# With npx
npx dataforseo-mcp-server http --configuration field-config.json

# Local mode
npx dataforseo-mcp-server local --configuration field-config.json

Configuration Behavior

• If a tool is configured: Only the specified fields will be returned in the response

• If a tool is not configured: All available fields will be returned (default behavior)

• If no configuration file is provided: All tools return all available fields

Example Configuration File

The repository includes an example configuration file field-config.example.json with optimized field selections for common tools:

{
  "supported_fields": {
    "backlinks_backlinks": [
      "id",
      "items.anchor",
      "items.backlink_spam_score",
      "items.dofollow",
      "items.domain_from",
      "items.domain_from_country",
      "items.domain_from_ip",
      "items.domain_from_platform_type",
      "items.domain_from_rank",
      "items.domain_to",
      "items.first_seen",
      "items.is_broken",
      "items.is_new",
      "items.item_type",
      "items.last_seen",
      "items.links_count",
      "items.original",
      "items.page_from_encoding",
      "items.page_from_external_links",
      "items.page_from_internal_links",
      "items.page_from_language",
      "items.page_from_rank",
      "items.page_from_size",
      "items.page_from_status_code",
      "items.page_from_title",
      "items.prev_seen",
      "items.rank",
      "items.ranked_keywords_info.page_from_keywords_count_top_10",
      "items.ranked_keywords_info.page_from_keywords_count_top_100",
      "items.ranked_keywords_info.page_from_keywords_count_top_3",
      "items.semantic_location",
      "items.text_post",
      "items.text_pre",
      "items.tld_from",
      "items.type",
      "items.url_from",
      "items.url_from_https",
      "items.url_to",
      "items.url_to_https",
      "items.url_to_spam_score",
      "items.url_to_status_code",
      "status_code",
      "status_message"
    ],
    ...
  }
}

Nested Field Support

The configuration supports nested field paths using dot notation:

• "rating.value" - Access the value field within the rating object

• "items.demography.age.keyword" - Access deeply nested fields

• "meta.description" - Access nested object properties

Field Discovery

To discover available fields for any tool:

1. Run the tool without field configuration to see the full response

2. Identify the fields you need from the API response

3. Add those field paths to your configuration file

Creating Your Own Configuration

1. Copy the example file:

cp field-config.example.json my-config.json

2. Modify the field selections based on your needs

3. Use your custom configuration:

npx dataforseo-mcp-server http --configuration my-config.json
