Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

{ "mcpServers": { "prozorro": { "command": "prozorro-mcp-server", "env": { "PROZORRO_API_TOKEN": "your-api-token-here", "PROZORRO_SERVICE_URL": "mcp-api-url-here" } } } }

Restart Claude Desktop and you're ready to use the server!

Note: On Linux/macOS, if you encounter permission issues, you may need to use sudo npm install -g prozorro-mcp-server or configure npm to use a user directory.

Method 2: Install from GitHub

Install globally via npm from GitHub:

npm install -g git+https://github.com/VladyslavMykhailyshyn/prozorro-mcp-server.git

Add to Claude Desktop configuration:

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{ "mcpServers": { "prozorro": { "command": "prozorro-mcp-server", "env": { "PROZORRO_API_TOKEN": "your-api-token-here", "PROZORRO_SERVICE_URL": "mcp-api-url-here" } } } }

Restart Claude Desktop - The server will be ready to use!

Method 3: Local Development Installation

Clone the repository:

git clone https://github.com/VladyslavMykhailyshyn/prozorro-mcp-server.git cd prozorro-mcp-server

Install dependencies:

npm install

Build the project:

npm run build

Add to Claude Desktop configuration (use absolute path):

{ "mcpServers": { "prozorro": { "command": "node", "args": ["/absolute/path/to/prozorro-mcp-server/build/index.js"], "env": { "PROZORRO_API_TOKEN": "your-api-token-here", "PROZORRO_SERVICE_URL": "https://prozorro.gov.ua" } } } }

Configuration

The server requires specific environment variables to function correctly. You can set these in the Claude Desktop configuration or in a .env file for local development.

Variable	Description	Required	Example
`PROZORRO_API_TOKEN`	Your Bearer token for the Prozorro API	Yes	`Bearer abc123...`
`PROZORRO_SERVICE_URL`	Base URL for the API	Yes	`https://mcp-service-url....`

Common Usage Workflows

Workflow 1: Search Tenders by Organization

1. Use search_tenders with EDRPOUCode to find all tenders from a specific organization 2. Review the returned tender details including dates, amounts, and status 3. Filter results by date range if needed

Workflow 2: Find Recent Tenders

1. Use search_tenders with dateFrom and dateTo parameters 2. Optionally filter by organization name using legalName 3. Limit results for better performance

Troubleshooting

Server not appearing in Claude Desktop

Check that the path in claude_desktop_config.json is correct
Ensure you've built the project with npm run build
Verify that Node.js is installed (version 18 or higher required)
Restart Claude Desktop
Check Claude Desktop logs for errors

API Request Failures

Verify your PROZORRO_API_TOKEN is valid and not expired
Check that PROZORRO_SERVICE_URL is correct
The Prozorro API may have rate limits - consider adding delays between requests
Network connectivity to prozorro.gov.ua is required
Some tenders might be temporarily unavailable

Authentication Errors

Ensure your API token includes the Bearer prefix if required
Check that your token has the necessary permissions
Verify the token hasn't expired
