@okaneland/mcp
A small Model Context Protocol server that gives AI agents two things from Okane Land:
| Tool | What it does |
|---|---|
get_ai_tool_prices | Current, human-verified pricing for 100+ AI tools solo builders use, with what's free, what a real month costs, the gotcha, and the last-verified date. Fetched live from the maintained price index. |
calculate_ai_margin | Turns an AI product's MRR into what you actually keep after the token bill, card fees, failed payments, refunds, and tax, plus the break-even price and usage cap. |
It runs on the user's machine over stdio, so there is nothing to host. get_ai_tool_prices fetches the public /api/v1/prices.json at call time, so the data is always as fresh as the site's monthly re-verification.
Install
Add it to your MCP client's config (Claude Desktop, Cursor, Windsurf, and others use the same shape):
{
"mcpServers": {
"okaneland": {
"command": "npx",
"args": ["-y", "@okaneland/mcp"]
}
}
}
Restart the client. The two tools appear in any agent you run there.
Example
You: I want a $20/mo AI writing tool on Claude Sonnet. What do similar tools charge, and would $20 keep money at 500 users?
The agent calls get_ai_tool_prices and calculate_ai_margin, then answers from real data: comparable tools charge more, and at 500 users on a Sonnet-class blend you keep about $3,260/mo (33%), staying profitable down to a $12.25 price or up to 3.3M tokens per user.
Tool reference
get_ai_tool_prices
Inputs (all optional): category, query, id, limit. Returns the matching tool rows plus the index's updated date, method, and source page.
calculate_ai_margin
Inputs: pricePerMonth, payingCustomers, blendedTokenPricePerM, tokensPerUserM, and optional monthlyChurnPct (6.1), intlCardPct (40), vatPct (0), failedPaymentsPct (9), refundsPct (3). Returns gross, tokenBill, cardFees, failedPayments, refunds, tax, keep, keepPct, perCustomerKeep, customersReplacedMonthly, breakEvenPrice, breakEvenTokensPerUserM, and tokenCostExceedsPrice.
Privacy
The server fetches only the public price index over HTTPS and sends nothing about you. The margin calculation runs entirely locally.
Develop
npm install
npm run build # tsc -> dist/
npm test # unit tests pin the margin math to the web calculator
npm run smoke # spins up the server, runs the MCP handshake, calls both tools
The margin math in src/margin.ts is a port of Okane Land's margin calculator; src/margin.test.ts pins its known-good outputs so the two cannot silently drift.
