The underground agent wraps 68 MCP tools behind a single MCP server (vault-model-mcp). Tools are grouped here by category. The agent is in Phase 7 of active development — the catalog grows as new equipment classes ship.
Vault assembly — 5 tools
Create vaults, add conduit ports, install equipment, export complete vault models.
Conduit routing — 7 tools
Segment creation, conduit runs, conductor placement, bends, trench profiles. Wall-face and elevation placement on padmount enclosures; auto-connect picks optimal port pairs.
Fill & pulling — 7 tools
NEC conduit fill percentage, three-cable jam detection (D/d 2.8–3.2 danger zone), pulling tension through bends, intermediate vault placement when tension exceeds limits.
Ampacity & thermal — 4 tools
Neher-McGrath calculations with soil, depth, and grouping corrections. Emergency ratings and voltage drop.
Sizing & clearances — 5 tools
Vault selection, OSHA / NEC 110.34 working space, bending radius, pad-mount clearances.
Network topology — 8 tools
Unified overhead + underground circuit graphs. Shortest path, alternate feeds, single points of failure. This is where the two domains cross — risers stitch the OH and UG graphs together.
Riser transitions — 3 tools
Dead load calculations, conduit sizing, termination and arrester specs.
What-if studies — 9 tools
Overhead-to-underground conversion, voltage cutover, reconductoring, storm hardening, wildfire risk scoring, circuit reconfiguration.
Fault & protection — 4 tools
Cable fault withstand (ICEA), concentric neutral duty, arc flash (IEEE 1584).
Duct bank design — 4 tools
Layout optimization, multi-circuit derating, concrete encasement, trench dimensions.
