Orca AI MCP Server

A Model Context Protocol (MCP) server that integrates with Orca AI's HUNT Platform API for finding information about people, companies, and other entities.

About Orca AI

Orca AI is a leading provider of investigative intelligence and due diligence solutions. The HUNT platform provides access to comprehensive datasets for person and entity research across multiple authoritative sources.

This MCP server connects to the Orca AI API to enable AI assistants to search and retrieve information from the HUNT platform directly within their workflows.

Features

• Dynamic Configuration: Directory-based configuration using local .orcaai.json files

• HUNT API Integration: Search across authoritative datasets for people, companies, and entities

• Flexible Authentication: API key-based authentication with environment variable fallback

• Context-Aware: Automatically detects and switches between different configurations

• Robust Error Handling: Built-in retry logic with exponential backoff

npm install
npm run build

Configuration

Local Configuration (Recommended)

Create a .orcaai.json file in your working directory:

{
  "apiUrl": "https://api.orcaai.io",
  "apiToken": "your-orca-ai-api-key-here",
  "settings": {
    "timeout": 30000,
    "retries": 3
  },
  "tools": {
    "hunt": true
  }
}

Environment Variables

Alternatively, use environment variables:

export ORCA_API_TOKEN="your-orca-ai-api-key"
export ORCA_API_URL="https://api.orcaai.io"
export ORCA_TIMEOUT="30000"
export ORCA_RETRIES="3"
export ORCA_TOOLS_HUNT="true"

Available Tools

HUNT Search

• get_hunt_results: Search across datasets for people, companies, and entities

  • Required: query - Search string (person name, company name, etc.)

  • Optional: nextToken - Pagination token for subsequent pages (v0.2 API)

Context Detection

• detect_orca_context: Detect current configuration and verify API connectivity

Authentication

This MCP server requires an Orca AI API key:

1. API Key Format: 40 alphanumeric characters

2. Header Used: x-api-key

3. Endpoint: https://api.orcaai.io

API Endpoints Used

• v0.2 HUNT API: POST /v0.2/hunt (default, supports pagination, max 100 results per page)

Usage Examples

Basic Person Search

// Search for a person
const results = await callTool("get_hunt_results", {
  query: "Vladimir Putin"
});

Company Search

// Search for a company
const results = await callTool("get_hunt_results", {
  query: "Microsoft Corporation"
});

Paginated Search

// Get first page
const page1 = await callTool("get_hunt_results", {
  query: "John Smith"
});

// Get next page using returned token
const page2 = await callTool("get_hunt_results", {
  query: "John Smith",
  nextToken: "returned-token-from-page1"
});

Configuration Check

// Verify your configuration
const context = await callTool("detect_orca_context");

Response Format

HUNT search results include:

• query: Original search query

• nextToken: Pagination token (v0.2 only)

• huntDocuments: Array of matching records containing:

  • primaryName: Main identified name

  • names: Array of alternative names

  • dataset: Source dataset information

  • rawData: Unstructured text about the record

  • values: Array of relevant values/attributes

  • tabularData: Structured data fields

Development

Available Scripts

• npm run dev - Start development server with hot reload

• npm run build - Build the project

• npm run start - Start the built server

• npm run test - Run tests

• npm run type-check - Check TypeScript types

• npm run clean - Clean build directory

Testing the Server

# Build and start the server
npm run build
npm start

# In another terminal, test with Claude Code
# The server runs on stdio and communicates via MCP protocol

How to Start and Use

Step 1: Configure Your API Key

# Copy the example configuration
cp .orcaai.json.example .orcaai.json

# Edit .orcaai.json and add your API key

Step 2: Build the Server

npm run build

Step 3: Configure Claude Code

Add the server to your Claude Code MCP configuration:

{
  "mcpServers": {
    "orca-ai": {
      "command": "node",
      "args": ["dist/index.js"]
    }
  }
}

Step 4: Restart Claude Code

Restart Claude Code to load the MCP server.

Step 5: Use the Tools

Ask Claude Code to:

• "Search for information about [person/company] using Orca AI"

• "Check my Orca AI configuration"

• "Search the HUNT platform for [query]"

Error Handling

The server handles common API errors:

• 401 Unauthorized: Invalid or missing API key

• 400 Bad Request: Invalid query parameters

• 429 Rate Limited: Too many requests

• 5xx Server Errors: Automatic retry with exponential backoff

Troubleshooting

Common Issues

1. "No configuration found"

   • Ensure .orcaai.json exists with valid API key

   • Check environment variables are set correctly

2. "Authentication failed"

   • Verify your API key is 40 characters and valid

   • Ensure no extra spaces in configuration

3. "Rate limit exceeded"

   • Wait before making another request

   • Consider implementing delays between requests

4. Server not starting

   • Run npm run build first

   • Check Node.js version (requires 18+)

   • Verify all dependencies installed: npm install
