MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-pdf-rasterize-pages": {
      "name": "pdf-rasterize-pages",
      "description": "Render PDF pages into high-fidelity image sequences (PNG/JPG/WebP) with configurable DPI and page range",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=pdf-rasterize-pages",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "pdf-rasterize-pages",
    "arguments": {
  "pdfFile": "/public/samples/pdf/sample-multipage.pdf",
  "pageRange": "1,3,5-6",
  "dpi": 300,
  "format": "png",
  "jpegQuality": 92,
  "webpQuality": 90,
  "outputMode": "zip",
  "filePrefix": "report_png"
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
