Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-json-pointer": {
      "name": "json-pointer",
      "description": "Navigate and extract values from JSON using JSON Pointer (RFC 6901)",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=json-pointer",
      "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": "json-pointer",
    "arguments": {
  "jsonData": "{\"user\": {\"name\": \"John\", \"age\": 30}, \"items\": [1, 2, 3]}",
  "pointerPath": "e.g., /user/name or /items/0",
  "operation": "get"
}
  }
}

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).
