Veteran dev's GSC Wizard MCP does the heavy lifting in ClickHouse, LLM gets conclusions only
DutchSEOnerd · reddit · 2026-09-25
A developer with 30 years of website building experience (including sites with 50M+ URLs) shares the architecture behind GSC Wizard, a Search Console MCP built on a core principle: server-side analysis is the entire point.
- Search Console analysis can't fit in a chat context window, so heavy lifting runs server-side in ClickHouse
- The model only receives conclusions, not raw data — framed as why he "stopped letting LLMs do arithmetic"
- He (admittedly biased) calls it the best Search Console MCP available in 2026
