pound.one missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

adjust
adjust_for_inflation
Compare GBP purchasing power between years, with prices, wages and housing context. RPI covers 1948 onwards; CPI covers 1988 onwards. "now" means the latest stored observation, not a live price.
calculate
calculate_take_home
Employee income tax and National Insurance for 2026/27, or the gross salary needed for a target net income. England, Wales and Northern Ireland only; Scotland is unsupported. Excludes pensions, student loans, benefits and other income. Includes a historical UK taxpayer income rank.
compare
compare_public_spending
Express a GBP amount as a share and duration of a stored 2025-26 public budget, with comparisons against other budgets. The NHS comparison uses England's DHSC day-to-day budget as a proxy. These are illustrative averages, not live spending rates.

pound.one — questions

Answers built from our own checks of this server.

What can pound.one do?
It exposes 3 tools, read directly from the server on our last check. Among them: adjust_for_inflation, calculate_take_home, compare_public_spending. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is pound.one working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 172 ms. The bar chart above shows every period we have measured.
How do I connect pound.one?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does pound.one need an API key?
No. pound.one completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is pound.one?
It answers our handshake in 172 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
