Den Archi MCP server

What it does

den is an MCP server that provides curated Korean AEC (architecture, engineering, construction) expertise, connecting building codes, laws, and professional practice knowledge into a single graph. It answers not just where information is written, but why regulations exist, what order processes follow, and how concepts differ from each other, refusing to answer when it lacks grounding.

• Look up specific building code requirements with their clause references, such as indoor fire hydrant height or parking space dimensions.
• Understand the causal reasoning behind construction practices and regulations, like why concrete requires curing or what physical principles drive durability.
• Determine the correct sequence and dependencies for construction processes, such as reinforced concrete structural stages with parallel and sequential steps clearly marked.

Tools this server exposes

Tool	Does
answer_why	Explains causal relationships behind regulations and construction phenomena using connected pathways in the knowledge graph.
scenario	Provides construction process sequences with dependencies and ordering constraints.
compare	Contrasts two construction methods, concepts, or specifications side-by-side.
enumerate	Lists categories, components, or classifications of a construction topic.
site_context	Converts geographic information into relevant climate and regulatory conditions.
review_plan	Checks floor plans against applicable building codes and regulations.
emotional_palette	Describes the sequence of spatial experiences and atmosphere transitions through a space.
path_between	Shows connections between two concepts or predecessors and successors of a single concept.
traverse	Explores adjacent relationships and connections within the knowledge graph.
k_snippets	Retrieves specific figures, clauses, and original text from Korean building standards and laws.
evidence_for	Confirms the grounds supporting a causal relationship between two connected elements.
define	Provides definitions for construction and regulatory terminology.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
