Nothing serious here today

Today is the operative word: we check Docker Facts every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

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

image

check_image_tag

Does this image:tag exist, how big is it, and which platforms does it cover? Use this before writing a FROM line or a compose file. On a hit it returns size, platforms, arm64/amd64 support and the digest. On a miss it says whether the IMAGE exists but the tag is wrong, and lists real tags newest first so the caller can correct itself. Defaults to tag "latest" when none is given.

get_image_info

Repository facts: official status, pulls, stars, whether it is archived. Use to judge whether an image is the canonical one and still maintained. Archived images still pull but receive no security patches.

list_image_tags

Real tags for an image, most recently updated first. Use when choosing a tag rather than verifying one. Each entry carries size and platform list, so a choice can be made without a second call.

Docker Facts — questions

Answers built from our own checks of this server.

What can Docker Facts do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_image_tag, get_image_info, list_image_tags. 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 Docker Facts 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 183 ms. The bar chart above shows every period we have measured.

How do I connect Docker Facts?

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 Docker Facts need an API key?

No. Docker Facts 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 Docker Facts?

It answers our handshake in 183 ms on average, which is faster than 69% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
