UsefulAPI hosts a collection of hosted MCP servers that let MCP clients connect to third-party services such as Linear, Slack-like chat tools, billing, email, analytics, and observability products. Each server is provided as a hosted endpoint with its own README and MCP registry record, so users authorize once and use it without local installation.
From the registry: Calculate sales tax & VAT, record transactions and refunds, manage products and customers.
This server lives in a monorepo. The README covers the whole collection, so we can't extract a single canonical install. This README is for the usefulapi collection of hosted MCP servers, including Numeral as a subfolder entry. It does not provide Numeral-specific installation/config details here; each server has its own README and server.json under servers/numeral/.
