Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'https://api.elysiatools.com/en/api/tools/tide-and-lunar-distance-predictor' \
  -H 'Content-Type: application/json' \
  -d '{"moonAgeDays":0.2,"lunarDistanceKm":363300,"declinationDeg":5,"baselineRange":1}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/tide-and-lunar-distance-predictor

Parameters

Name	Type	Required	Description
moonAgeDays	number	Yes	0 = new moon; about 14.77 = full moon.
lunarDistanceKm	number	Yes	Perigee is about 363,300 km; apogee is about 405,500 km.
declinationDeg	number	Yes	Use a signed value; the absolute value affects this simplified model.
baselineRange	number	Yes	Typical local range used only to express the result in metres.

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-tide-and-lunar-distance-predictor": {
      "name": "tide-and-lunar-distance-predictor",
      "description": "Estimate spring/neap tide forcing and lunar-distance amplification with a transparent offline planning model.",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=tide-and-lunar-distance-predictor",
      "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": "tide-and-lunar-distance-predictor",
    "arguments": {
  "moonAgeDays": 0.2,
  "lunarDistanceKm": 363300,
  "declinationDeg": 5,
  "baselineRange": 1
}
  }
}

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).
