# PDFgen

> PDFgen generates PDFs from HTML, Markdown, saved templates, or plain-English prompts. Use it from AI agents through the PDFgen MCP server (tool: `generate_pdf`) or from code through the REST API (`POST https://pdfgen.com/api/v1/generate`). Every request needs an API key (`pdfg_live_...`); the free plan includes 30 PDFs a month.

To give an agent a PDF tool, add this to its MCP client config:

```json
{
  "mcpServers": {
    "pdfgen": {
      "command": "npx",
      "args": ["-y", "@pdfgen/mcp"],
      "env": { "PDFGEN_API_KEY": "pdfg_live_xxx" }
    }
  }
}
```
