Clara — Personal Clean Air Planner

com.southlondonscientific/clara

Gives Claude access to personalized UK air quality exposure estimates based on where you live, work, and travel. This is the MCP interface to South London Scientific's Clara product, which models PM2.5 and NO2 exposure at the individual level. The description mentions it pairs with Hermes, their other MCP server that provides ambient monitoring data from UK public networks. Reach for this when you need to assess personal exposure rather than just checking station readings. It appears designed for exposure assessment workflows where you want Claude to reason about individual air quality impacts and suggest interventions that would actually reduce someone's pollutant intake based on their specific movement patterns and locations.
