mcp.json

{
  "mcpServers": {
    "elysiatools-pdf-to-json-structure-explorer": {
      "name": "pdf-to-json-structure-explorer",
      "description": "Extract structured OpenDataLoader JSON from a PDF and browse headings, paragraphs, tables, lists, pages, and bounding boxes in an explorer view",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=pdf-to-json-structure-explorer",

      "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-to-json-structure-explorer",
    "arguments": {
  "pdfFile": "/public/samples/pdf/brand-guidelines-pdf-example1.pdf",
  "useStructTree": true,
  "sanitizeSensitiveData": false,
  "pages": "",
  "nodeFilter": "all",
  "searchTerm": ""
}
  }
}

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.
