Open Index
UK public data by area: house prices, crime, deprivation, schools and more, each figure cited.
What it does
Open Index 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) and are not a test of the tool.

5 tools offered to AI assistants
search_places· Find UK places (nations, regions, councils, constituencies, towns, wards, neighbourhoods) and postcodes by name, with each one's official code, level and page URL. Also lists matching data layers.get_place· Published figures for one UK area: key figures by default, or every figure in one topic. Each figure has its period, publication date, rank, comparisons, source and a link to the figure on its page.get_ranking· Councils ranked on one measure across the UK, a nation or an English region, for the latest period. Measures each nation makes its own way (such as deprivation) are ranked within one nation only.compare_places· Two UK areas of the same level side by side on the same published figures, each with its own period and source. Key figures by default.lookup_postcode· The areas a Great Britain postcode sits in (council, constituency, ward, neighbourhood and more) with their codes and pages. A district (E8) or sector (E8 1) gives its councils. Northern Ireland postcodes are not available.
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
