Baby Age 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.

Available tools 5

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

baby

get_baby_age

Get a baby's exact age from a birth date - years, months, weeks, days, totals, zodiac sign, birthstone, the current and next milestone, and special-day dates (100 days, first birthday, 1000 days). Use for any 'how old is the baby' question instead of computing it yourself.

birthstone

get_birthstone

Get the full birthstone guide for a birth date's month: every stone (some months have three) with colors, hardness, sources and story, plus meaning for the baby, keepsake ideas, a safety note, the month's zodiac signs, quick answers, and a guide link. Always pass on the safety note with keepsake ideas.

milestone

get_milestone_dates

Get the exact calendar date of all 25 baby milestones for a given birth date (monthly, special days, and birthdays), each with days_left and whether it is reached. Use this to add baby milestones to a calendar.

milestones

list_milestones

List the 25 baby milestone types this tool knows (name, emoji, day offset from birth, group). No birth date needed. Use get_milestone_dates to turn these into real dates.

zodiac

get_zodiac_sign

Get the zodiac sign (Western astrology) for a birth date, with element, nickname, date range, and a guide link.

Baby Age — questions

Answers built from our own checks of this server.

What can Baby Age do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_baby_age, get_birthstone, get_milestone_dates, get_zodiac_sign, list_milestones. 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 Baby Age working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 403 ms. The bar chart above shows every period we have measured.

How do I connect Baby Age?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Baby Age need an API key?

No. Baby Age completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Baby Age?

It answers our handshake in 403 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Baby Age open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at babyagecalculator.com, which runs on its operator's own terms.
