[](https://www.npmjs.com/package/@atlasprzetargow/mcp)
[](./LICENSE)

## What is this?

The [Model Context Protocol (MCP)](https://modelcontextprotocol.io) lets AI assistants connect to external tools and data. This server exposes the Atlas Przetargów API to any MCP client, giving your AI assistant the ability to:

- **Search Polish public tenders** by keyword, CPV category, location, value, or deadline
- **Get full tender details** including buyer, CPV codes, estimated value, deadlines, optional AI-generated summary
- **Profile any procuring entity (zamawiający)** by NIP — including who wins their contracts most often
- **Profile any contractor (wykonawca)** by NIP — including which buyers they win from
- **Analyze market statistics** for any CPV category (count, median value, avg offers, avg deadline)
- **Compare provinces and cities** in procurement volume
- **Access a glossary** of 90+ Polish public procurement terms
- **Use guided workflows** (prompts) for tender analysis, buyer due diligence, and opportunity discovery

## Quick start (Claude Desktop)

### Option A — via `npx` (recommended, no install)

Edit your Claude Desktop config file:

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

Add:

```json
{
  "mcpServers": {
    "atlas-przetargow": {
      "command": "npx",
      "args": ["-y", "@atlasprzetargow/mcp"]
    }
  }
}
```

Restart Claude Desktop. The Atlas tools will appear in the tools panel.

### Option B — global install

```bash
npm install -g @atlasprzetargow/mcp
```

Then in `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "atlas-przetargow": {
      "command": "atlas-przetargow-mcp"
    }
  }
}
```

## Usage examples (in Claude Desktop)

> **"Find active construction tenders in Warsaw with budget 500k–5M PLN and show me the top 5"**

## Development

```bash
git clone https://github.com/atlasprzetargow/mcp-server.git
cd mcp-server
npm install
npm run build
npm run smoke   # runs all tools against production API

# Test locally in Claude Desktop:
# Point the "command" in claude_desktop_config.json to the absolute path of dist/index.js:
# "command": "node", "args": ["/abs/path/to/mcp-server/dist/index.js"]
```

## Rate limits & fair use

Atlas Przetargów API has a per-IP rate limit (30 req/min for LLM endpoints, more for public ones). The MCP server automatically retries 429 responses with exponential backoff.

If you hit rate limits frequently (e.g. in production automations), please reach out via [atlasprzetargow.pl/kontakt](https://atlasprzetargow.pl/kontakt) for higher-tier access.
