What it does
PostCode Check is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

2 tools offered to AI assistants
validate_postcode· Check whether a postal code has a valid format for a country and return its normalized form (uppercase, official space or hyphen), a format example and the country name. Example: country "NL", code "1234ab" → valid true, normalized "1234 ABlist_countries· List every supported country and territory with its ISO code, English name, whether it uses postal codes, a format example and the local name for the code (zip, eircode, PIN…). Read-only. Same data as GET /v1/countries.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
