Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to reliness.co.uk, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server offering nine everyday calculators: tips, BMI, calories, age, grades, GPA, leap year, batting average and date formatting.

What you can do: Compute money and health figures: tip amount and total, BMI in metric or imperial units, and daily calorie needs with protein, carb and fat grams
Work with education numbers: convert a percentage to a letter grade and average grade points into a GPA
Handle dates: calculate age from a birth date, and reformat dates and times with strftime codes while rejecting impossible dates
Run small utility checks: leap year test and baseball batting average at a chosen precision
When to use it: Useful when you want an assistant to produce quick, formula-backed everyday numbers — a tip split, a BMI or calorie estimate, a GPA, an age or a reformatted date — without doing the arithmetic itself.
Requirements: A remote streamable HTTP endpoint; no local install. No account is required for the free daily allowance. An optional Authorization header with a bearer key, obtained from the provider's key endpoint, raises the allowance.

Before you install

Each tool call costs one credit, and the free daily allowance is limited; a key is needed for heavier use. The optional Authorization header carries a secret key. Health figures such as BMI and calorie intake are generic formula outputs, not medical advice.

Installation

In SourceWeft

Open UK Data: Everyday calculators in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/uk.co.reliness%2Feveryday-calculators/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
