Overview

AI-generated overview

Remote MCP tool that computes resale selling fees, net profit, ROI and break-even sale price for a given purchase and sale price.

What you can do
  • Calculate resale economics from a purchase price and sale price
  • Return selling fee, net profit, ROI and break-even sale price in one call
  • Round results to two decimals, with ROI null for a zero purchase price and break-even null when the fee is 100 percent or more
When to use it
Useful when you want an assistant to quickly check whether a resale or flip is profitable, compare margins across items, or find the sale price at which a listing breaks even.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. Network access to the hosted endpoint is needed.
Before you install
The registry description calls it a paid tool, so using it may involve cost; confirm pricing before relying on it. Calculations are simple arithmetic on the prices you supply, so verify the fee assumptions match your marketplace.

Installation

In SourceWeft

  1. Open Resale Margin Calculator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.weromon%2Fresale-margin-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
