Common questions

Is Plutocalcdesigner MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.5.1) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

Plutocalc Designer MCP Server

MCP server for the Plutocalc Designer REST API, providing access to water and wastewater treatment system design tools through the Model Context Protocol.

Registry Name: io.github.danpeig/plutocalcdesigner-mcp

Version: 2.5.1

MCP server URL: https://www.plutocalc.com/designer/mcp

OpenAPI specs: https://www.plutocalc.com/designer/server/openapi.json

About Plutocalc Designer

Plutocalc Designer is an online engineering tool for sizing water and wastewater treatment systems. Engineers select a design model, fill in a calculation template, and run the computation to receive a completed template with design results. Learn more at https://www.plutocalc.com/designer.


Using Plutocalc Designer from your AI platform

There are three ways of connecting Plutocalc Designer to AI applications:

  • Connecting via the MCP server (recommended)
  • Connecting directly to the API using OpenAPI specs (alternative)
  • Hosting your own instance of the MCP server (for developers)
Connecting via the MCP server (automatic)

The easiest way to use Plutocalc Designer with your AI assistant is through the MCP Registry:

  1. In Claude Desktop or your MCP-compatible client, search for:
   plutocalcdesigner-mcp

or

   io.github.danpeig/plutocalcdesigner-mcp
  1. Click "Add" or "Install" - The server will be automatically configured.
  1. Start using it! Ask your AI assistant:
  • "List available wastewater treatment models"
  • "Get the template for the stripping tower"
  • "Help me design a biological treatment system"
Connecting via the MCP server (manual)

If you need to configure manually, add this to your MCP client configuration:

For Claude Desktop (claude_desktop_config.json):

{

"mcpServers": { "plutocalcdesigner": { "url": "https://www.plutocalc.com/designer/mcp", "transport": "http" } } }

For other MCP clients:

  • Server URL: https://www.plutocalc.com/designer/mcp
  • Transport Type: HTTP
  • Name: plutocalcdesigner (or any name you prefer)
Connecting directly to the API using the OpenAPI specifications

Another way to connect AI models to Plutocalc Designer is use the API directly. In this case, the model can retrieve instructions from the OpenAPI json specifications available at https://www.plutocalc.com/designer/server/openapi.json

A more detailed description of the API with instructions and examples, suitable for humans or LLMs, can be found in: https://www.plutocalc.com/designer/api.html

Hosting the MCP server

This method hosts the MCP server only, not the Plutocalc Designer. The local server requires internet connectivity to connect to the Plutocalc Designer API.

Use this method if you are facing connectivity issues with Plutocalc Designer MCP server or for development purposes.

# Clone the repository

git clone https://github.com/danpeig/plutocalcdesigner-mcp.git cd plutocalcdesigner-mcp

Install dependencies

npm install

Start the server

npm start

The server will start on port 3003 by default (configurable via `PORT` environment variable).

If you need to check if the server is working, see TEST_CLIENT_README.md for detailed instructions.
