Search and cite the Russian Orthodox patristic corpus (azbyka.ru) from any MCP-capable agent. Indexes ~2,100 works by 86 Church Fathers and ascetic writers (726K paragraphs, 1.98M bge-m3 embedding windows) in a Postgres + pgvector backend. Ships: - HTTP MCP server with 6 tools: read_passage, lexical_search, semantic_search, list_authors, list_works, expand_concept (Church-Slavonic / archaic synonym expansion). - "teo-search" subagent — restricted to search tools, returns candidate citations with snippets so the main agent can't quote without verifying. - "theology-router" skill — auto-activates on patristic/theological questions and enforces the search-then-read pattern. All passages return verbatim with canonical slugs of the form author/work/chapter/paragraph, linked back to azbyka.ru. Self-hostable — swap the MCP URL to your own backend.
