Effective Renal Plasma Flow Calculator (PAH Clearance)

Estimate ERPF from PAH clearance (C = U·V/P, normal ~500–700 mL/min), plus true RPF, renal blood flow from Hct, and filtration fraction from GFR. Not medical advice.

Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'http://127.0.0.1:3003/en/api/tools/renal-plasma-flow' \
  -H 'Content-Type: application/json' \
  -d '{"uPah":6.5,"pPah":0.01,"vFlow":1,"extraction":0.9,"hct":0.45,"gfr":125,"decimalPlaces":1}'

API reference

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

Endpoint

HTTP

POST http://127.0.0.1:3003/en/api/tools/renal-plasma-flow

Parameters

Name	Type	Required	Description
uPah	number	Yes	Urine PAH concentration. Must use the same units as plasma PAH.
pPah	number	Yes	Plasma PAH concentration in the linear (non-saturating) range.
vFlow	number	Yes	Urine flow rate in mL/min.
extraction	number	No	PAH extraction ratio E (fraction removed in one renal pass). Default 0.90.
hct	number	No

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-renal-plasma-flow": {
      "name": "renal-plasma-flow",
      "description": "Estimate ERPF from PAH clearance (C = U·V/P, normal ~500–700 mL/min), plus true RPF, renal blood flow from Hct, and filtration fraction from GFR. Not medical advice.",

      "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": "renal-plasma-flow",
    "arguments": {
  "uPah": 6.5,
  "pPah": 0.01,
  "vFlow": 1,
  "extraction": 0.9,
  "hct": 0.45,
  "gfr": 125,
  "decimalPlaces": 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).
