Overview

AI-generated overview

A free, no-auth remote MCP server offering 16 small read-only calculators for business, pricing, ads, app store, and Japan trip questions.

What it does
Exposes 16 deterministic, read-only tools over streamable HTTP, including business idea scoring, price headroom, 30-day cash checks, email list value, hotel OTA commission, SaaS self-hosting savings, open-source SaaS alternatives, Google/Meta ads notice risk, App Store 4.2/4.3 precheck, faceless YouTube reality check, AI infrastructure bottlenecks, viral attention patterns, and Japan trip planning. Several tools are quizzes or option listings. Every tool is also available as a plain JSON HTTP API with OpenAPI 3.1 descriptions.
When to use it
Useful when an assistant needs quick rules-of-thumb estimates or checklists for founder, pricing, marketing, app store, or travel questions, without setting up accounts or keys. Best for exploratory or educational answers rather than authoritative financial, legal, or investment decisions.
Requirements
Nothing to install or authenticate: connect to the remote streamable HTTP endpoint. No API key, account, or environment variables are declared. Network access to the endpoint is required; stdio-only clients need an npx bridge.
Before you install
Results are explicitly rules of thumb and educational estimates, not financial, legal, or investment advice, and each result carries a disclaimer. All tools are described as read-only and idempotent, so no data is written or deleted. Requests go to a third-party hosted endpoint, so avoid sending sensitive business or personal data.
