Install it

  • Hosted endpoint: not open for this server yet - use the .mcpb bundle or build from source below. The other 46 servers in the suite are already hosted.
  • Claude Desktop, one click: download the .mcpb bundle
  • From source: git clone https://github.com/theluckystrike/mcp-servers then build servers/loan-calculator.
  • npm: the package mcp-loan-calculator is staged and publishes shortly; the .mcpb bundle is the supported install until then.

Tools it exposes

The tool list is published in the server manifest (server.json) and the repository README.

Pricing

Free to run locally, forever. The Pro licence is $19, one time, lifetime — it changes only the hosted endpoint’s saved-report cap, never the tools. All 58 servers together are $39 as a bundle instead of $1102 bought one at a time.
