Common questions
Is Flat Rate Math safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 25 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Rust on your computer.
What can I use instead?

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 request fixed bid: $84,000 total, $2,800 per request hire: $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.
