# Voyage and Consumption MCP Server

A TypeScript-based server for handling voyage and consumption operations, vessel position tracking, and weather data management.

## Features

- Document parsing and processing
- Casefile management
- Vendor search and contact information
- Purchase requisition handling
- Expense tracking
- Budget management
- Typesense integration for search
- MongoDB integration for data storage

## Prerequisites

- Node.js (v18 or higher)
- MongoDB
- Typesense
- OpenAI API key
- LlamaParse API key
- Perplexity API key

## Configuration

You can configure the server in three ways:

### 1. Environment-Specific Configuration Files

The server now supports environment-specific configuration files. Create a file named `.env.{environment}` where `{environment}` matches your NODE_ENV value:

```
.env.development  # Used when NODE_ENV=development (default)
.env.production   # Used when NODE_ENV=production
.env.staging      # Used when NODE_ENV=staging
.env              # Fallback if no environment-specific file is found
```

To use a specific environment:

```bash
NODE_ENV=production node dist/index.js
```

See the `env.production.example` file for a template of production environment variables.

### 2. Environment Variables (.env file)

Create a `.env` file in the root directory:

```env
MONGO_URI=mongodb://localhost:27017
DB_NAME=mcp_voyage
TYPESENSE_HOST=localhost
TYPESENSE_PORT=8108
TYPESENSE_PROTOCOL=http
TYPESENSE_API_KEY=your_typesense_api_key
OPENAI_API_KEY=your_openai_api_key
LLAMA_API_KEY=your_llama_api_key
VENDOR_MODEL=gpt-4
S3_API_TOKEN=your_s3_api_token
S3_GENERATE_HTML_URL=your_s3_generate_html_url
LLAMA_PARSE_URL=your_llama_parse_url
PERPLEXITY_API_KEY=your_perplexity_api_key
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret
GOOGLE_REDIRECT_URI=your_google_redirect_uri
GOOGLE_API_KEY=your_google_api_key
GOOGLE_SEARCH_ENGINE_ID=your_google_search_engine_id
COHERE_API_KEY=your_cohere_api_key
COMPANY_NAME=your_company_name
# API Configuration
SNAPSHOT_URL=https://dev-api.siya.com/v1.0/vessel-info/qna-snapshot
JWT_TOKEN=your_jwt_token_here
```

### 3. Command Line Arguments

Command line arguments will override values from the `.env` file:

```bash
node dist/index.js \
  --mongo-uri mongodb://localhost:27017 \
  --db-name mcp_voyage \
  --typesense-host localhost \
  --typesense-port 8108 \
  --typesense-protocol http \
  --typesense-api-key your_api_key \

  --llama-api-key your_llama_key \
  --vendor-model gpt-4 \
  --s3-api-token your_s3_token \
  --perplexity-api-key your_perplexity_key \
  --company-name your_company_name
```
