Flat Rate Math

[Flat Rate Math MCP server]

flatratemath MCP server

A Model Context Protocol server that prices three ways of paying for software work on one number: total cost per delivered request. It is the stdio version of the flatratemath CLI, one Python file, standard library only, nothing to install.

Tools

cost_per_request prices a single lane. Give it a mode (bid for a one-time fixed price, salary for a fully loaded monthly hire, flat for a monthly subscription), the dollar rate, the months the work stays alive, and the number of discrete requests you expect to submit.

compare_lanes takes up to three lanes and ranks them by cost per request. An $84,000 fixed bid, an $18,290/month hire, and a $5,995/month flat subscription over 12 months and 30 requests come back as:

flat sub: $71,940 total, $2,398 per requestfixed bid: $84,000 total, $2,800 per requesthire: $219,480 total, $7,316 per request

The flat lane in that example is a real one: the unlimited development subscription at Poket Dev. I kept redrawing the same spreadsheet for clients choosing between those lanes, so the math exists as a CLI and now as a server an agent can call.

Install

Clone the repo and point your MCP client at the file:

git clone https://github.com/scrapertweeter3-prog/mcp-flatratemath

Client command: python3 /path/to/mcp-flatratemath/server.py

The wire side is JSON-RPC 2.0 over stdio, one JSON object per line (newline-delimited JSON, the MCP stdio transport). Handshakes answered: initialize, ping, tools/list, tools/call.
