Overview

AI-generated overview

Remote MCP server for FinFam's free financial calculators (rent vs buy, mortgage, retirement) and its twice-daily money-news digest.

What you can do
  • Search financial calculators by natural-language question or topic
  • Inspect a calculator's input/output contract, field types, defaults and hints
  • Run a calculation with supplied field values
  • Read the formulas of calculators published as open source
  • Fetch the current FinFam Pulse money-news digest
  • Search past Pulse editions by topic, including their story cards and sources
When to use it
Useful when a user asks a personal-finance question that a calculator answers better than prose, such as rent versus buy or mortgage and retirement scenarios, or asks what is happening in markets and the economy right now.
Requirements
A remote streamable HTTP endpoint; no package, environment variables or headers are declared, and no authentication is declared.
Before you install
Calculations send the user's financial inputs (amounts, rates, counts) to a third-party service. Pulse content and calculator results come from FinFam and should be treated as informational, not financial advice.

Installation

In SourceWeft

  1. Open FinFam Financial Calculators 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/app.finfam%2Fcalculators/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
