MTender MCP OCDS Server

An MCP (Model Context Protocol) server for accessing Moldova's public procurement data through the MTender API.

Overview

This server provides access to the MTender public procurement system of Moldova, which implements the Open Contracting Data Standard (OCDS). It allows AI assistants to search for tenders, access tender details, budget information, funding sources, and analyze tender documents.

Code Structure

The server is organized into a modular structure for better maintainability:

mtender-server/
├── src/
│   ├── index.ts                  # Main entry point
│   ├── api/
│   │   └── mtender-client.ts     # MTender API client with axios
│   ├── handlers/
│   │   ├── resources.ts          # Resource handlers
│   │   ├── tools.ts              # Tool handlers
│   │   └── utils.ts              # Shared handler utilities
│   └── utils/
│       └── logger.ts             # Logging utility
├── build/                        # Compiled JavaScript
├── logs/                         # Log files
├── Dockerfile                    # Docker configuration
├── docker-compose.yml           # Docker Compose configuration
└── .dockerignore                # Docker ignore file

This modular structure makes the code easier to maintain, understand, and extend.

OCDS Schema Coverage

This MCP server provides comprehensive access to the MTender API, which implements the Open Contracting Data Standard. Here's the coverage of the OCDS schema:

OCDS Component	Support Level	Notes
Release Packages	✅ Full	Supported through direct API access
Records	✅ Full	Supported through direct API access
Planning Section	✅ Full	Accessible through budget endpoints
Tender Section	✅ Full	Core tender data fully supported
Award Section	✅ Full	Included in tender responses
Contract Section	✅ Full	Included in tender responses
Implementation Section	⚠️ Partial	Limited by MTender API capabilities
Organizations/Parties	✅ Full	Included in all responses
Items	✅ Full	Included in tender, award, contract sections
Values	✅ Full	Monetary values with currency information
Periods	✅ Full	Date ranges for various process stages
Documents	✅ Full	Document references and content extraction
Milestones	✅ Full	Process milestones included in responses
Transactions	⚠️ Partial	Limited by MTender API capabilities
Amendments	✅ Full	Changes to processes are tracked
Related Processes	✅ Full	Links between related contracting processes

The server provides a complete interface to all data available through the MTender API, making it a full-featured OCDS client within the constraints of the underlying API.

Note on Partial Support: The Implementation Section and Transactions are marked as partial because the MTender system in Moldova currently does not include data for the implementation stage of the contracting process. The MTender API only covers four stages: planning, tender, award, and contract, but does not include contract implementation data. This is a limitation of the underlying API, not of this MCP server.

Installation

From GitHub

You can clone the repository directly from GitHub:

git clone https://github.com/yoda-digital/mcp-mtender-server.git
cd mcp-mtender-server
npm install
npm run build

Manual Installation

1. Clone this repository
2. Install dependencies:

   npm install
   

3. Build the server:

   npm run build
   

4. (Optional) Make the server globally available:

   npm link
   

Docker Setup

The MTender OCDS Server can be run in a Docker container, which provides an isolated and consistent environment.

Building the Docker Image

To build the Docker image:

cd mtender-server
docker build -t mtender-mcp-server .

Running with Docker

To run the server using Docker:

docker run -v $(pwd)/logs:/app/logs mtender-mcp-server

This command mounts the local logs directory to the container's logs directory, ensuring that logs are persisted on the host machine.

Using Docker Compose

For a more convenient setup, you can use Docker Compose:

cd mtender-server
docker-compose up -d

This will build the image if it doesn't exist and start the container in detached mode.

To stop the container:

docker-compose down

Docker Configuration

The Docker setup includes:

• Multi-stage build for smaller image size
• Alpine-based Node.js image for minimal footprint
• Production-optimized dependencies
• Volume mounting for logs persistence
• Environment variable configuration

Usage

Running the Server

node build/index.js

Or if you've linked it globally:

mtender-server

Testing

There are several ways to test the server:

Testing the MTender API Directly

The simple-test.js script tests the MTender API directly without using the MCP server:

node simple-test.js

This is useful for understanding the API structure and verifying that the API is accessible.

Testing the MCP Server

The mcp-test.js script demonstrates how to use the server programmatically:

node mcp-test.js

This script shows how to:

• Connect to the server
• List available resource templates and resources
• List available tools
• Search for tenders
• Get tender details
• Fetch and analyze tender documents

Interactive Testing with MCP Inspector

The MCP Inspector is a tool for testing MCP servers interactively:

npm run inspector

This will launch the MCP Inspector connected to this server, allowing you to test the resources and tools through a web interface.

Integrating with MCP Clients

A configuration template file (mcp-config-template.json) is provided to help you integrate this server with MCP clients like Claude Desktop or VSCode with the Cline extension.

For Claude Desktop:

1. Edit ~/Library/Application Support/Claude/claude_desktop_config.json (on macOS) or the equivalent path on your operating system.
2. Add the configuration from the template to the mcpServers object in the config file (replace /path/to/mtender-server with the actual path to your server).
3. Restart Claude Desktop.

For VSCode with Cline:

1. Edit /home/user/.config/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json (just a refference example,example on Linux) or the equivalent path on your operating system.
2. Add the configuration from the template to the mcpServers object in the config file (replace /path/to/mtender-server with the actual path to your server).
3. Restart VSCode.

Once integrated, you can access MTender data through natural language queries in your MCP client.

Development

Adding New Features

The modular structure makes it easy to add new features:

1. For new resources, update the handlers/resources.ts file
2. For new tools, update the handlers/tools.ts file
3. For API client changes, modify the api/mtender-client.ts file
4. For logging improvements, update the utils/logger.ts file

Contributing

Contributions to the MTender OCDS Server are welcome! You can contribute by:

1. Forking the GitHub repository
2. Creating a feature branch
3. Making your changes
4. Submitting a pull request

Logging

The server includes a comprehensive logging system that writes to files in the logs/ directory. This is useful for debugging and monitoring the server's operation.

Known Limitations

• Resource Timeouts: When accessing resources directly, you may encounter timeout issues due to the large amount of data being processed. This is especially true for the mtender://latest-tenders resource. The tools functionality (search_tenders, get_tender, etc.) works reliably and is the recommended way to access the data.

Example Queries

Here are some example queries you can use with Claude once the server is connected:

• "Show me the latest tenders from MTender"
• "Get details for tender ocds-b3wdp1-MD-1613996912600"
• "Find budget information for ocds-b3wdp1-MD-1613996472664"
• "What is the funding source for tender ocds-b3wdp1-MD-1613996912600?"
• "Search for tenders from January 2023 to June 2023"
• "Show me a summary of tender ocds-b3wdp1-MD-1613996912600"
• "Analyze tender ocds-b3wdp1-MD-1613996912600 and focus on the awards and contracts sections"
• "Find tenders with a limit of 10 results"
• "Analyze the tender documents for ocds-b3wdp1-MD-1613996912600"
