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-distributed-trace-decoder-waterfall-visualizer": {
      "name": "distributed-trace-decoder-waterfall-visualizer",
      "description": "Decode Jaeger, Zipkin, or OpenTelemetry trace JSON and render span timing, dependencies, and error hotspots as an interactive waterfall report",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=distributed-trace-decoder-waterfall-visualizer",
      "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": "distributed-trace-decoder-waterfall-visualizer",
    "arguments": {
  "traceJson": "{\n  \"data\": [\n    {\n      \"processes\": {\n        \"p1\": {\n          \"serviceName\": \"api-gateway\"\n        },\n        \"p2\": {\n          \"serviceName\": \"payment-service\"\n        }\n      },\n      \"spans\": [\n        {\n          \"traceID\": \"trace-1\",\n          \"spanID\": \"1\",\n          \"processID\": \"p1\",\n          \"operationName\": \"POST /checkout\",\n          \"startTime\": 1000000,\n          \"duration\": 320000,\n          \"references\": [],\n          \"tags\": []\n        },\n        {\n          \"traceID\": \"trace-1\",\n          \"spanID\": \"2\",\n          \"processID\": \"p2\",\n          \"operationName\": \"charge-card\",\n          \"startTime\": 1080000,\n          \"duration\": 180000,\n          \"references\": [\n            {\n              \"refType\": \"CHILD_OF\",\n              \"spanID\": \"1\"\n            }\n          ],\n          \"tags\": [\n            {\n              \"key\": \"error\",\n              \"value\": true\n            }\n          ]\n        }\n      ]\n    }\n  ]\n}",
