Overview

AI-generated overview

Remote BusCalc endpoint offering 33 bounded business, trade and financial calculation tools plus attributed public data lookups.

What you can do
  • Run business cost and pricing worksheets: cost per mile, markup vs margin, portion cost, hourly rate, equipment ownership, break-even, loan payments
  • Analyze decisions, sensitivity, uncertainty, value of information, statistics, probability, linear algebra and unit checks
  • Compute financial mathematics, lease economics, emergency contracting margins, fuel and energy costs
  • Look up public reference data: precious metal quotes, NWS weather and alerts, EIA and ECB prices, BLS, USDA and Census series, FEMA and flood sources
  • Convert measurements and time durations
When to use it
Useful when an assistant needs reproducible, formula-backed business arithmetic with stated assumptions and receipts, or quick lookups of official US and ECB reference data, rather than open-ended estimation.
Requirements
Remote streamable HTTP endpoint at buscalc.com; no authentication, environment variables or headers declared. Some lookup tools depend on third-party public data services (Gold API, NWS, EIA, ECB, BLS, USDA, Census, OpenFEMA, USGS).
Before you install
Lookup tools send requests to third-party public data providers. Results are unsigned calculation receipts, not certification, and quotes are dated snapshots that may be stale or revised. No trade execution, purchases or private project data; inputs must be supplied by the user rather than invented.

Installation

In SourceWeft

  1. Open BusCalc — Business & Trade Calculations 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/com.buscalc%2Fcalculations/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
