Most metals and crypto servers proxy a live quote; this one accumulates a daily record in your own DynamoDB, which is what makes range questions answerable at all — at the cost of deploying the Lambda and table into your AWS account first and letting them collect. The projection tool is a separate idea bolted on: a quick withdrawal-rate scenario with optional random returns, not a Monte Carlo simulation.
An MCP server over a price history you host yourself. A scheduled Lambda pulls gold, silver, palladium, copper, bitcoin and ether prices from a public API each weekday evening and writes them to DynamoDB under a date index; the server reads that history back, so "what did copper do last month" is a date-range query rather than a single live quote. A second tool is unrelated to metals: it projects a starting principal over thirty years at a growth rate you set, withdrawing a percentage each year, optionally with random annual returns and with withdrawals skipped after a losing year.
- Prices for gold, silver, palladium, copper, bitcoin or ether by name, for a date range or for the most recent record
- A history that accumulates from the day you deploy, indexed by date rather than by timestamp
- A thirty-year projection table: starting balance, withdrawal, balance after withdrawal, growth rate, growth amount and ending balance for each year
- Random annual growth as an option, so the projection reads as a scenario rather than a straight line
- Withdrawals skipped in the year following a negative one, when you ask for that rule
The server is the front end; the data lives in AWS resources you deploy yourself. That means an AWS account, the AWS and SAM command-line tools, and a deploy of the included template — two Lambda functions, a DynamoDB table, and an EventBridge rule that runs on weekdays at 22:00 UTC. Until that stack exists and has run at least once, the price tool has nothing to read. Python 3.10 or newer runs the server, and there is no key of the project's own to obtain.
