RackArchitect MCP

Connect or update a batch of up to 128 power and network cables between mounted device ports in the active rack, computing 3D Catmull-Rom splines, commercial length bins, and PoE or power budgets. Each entry in 'cables[]' upserts in place by 'cable_id' while leaving all other cables and mounted equipment untouched, pushes a recoverable undo snapshot, and persists rack.yaml atomically; port, speed, PoE, or clearance violations return status 'INVALID' with remediation_suggestions instead of throwing. Within each cable, endpoint 'face' is required only on pass-through couplers such as patch panels exposing identical 'port_id' values on both faces, 'preferred_portal_u' applies only to front-to-rear transitions, and 'vlan_id' or 'ip_cidr' annotate logical network links. Use when both endpoint devices are mounted inside the rack; use disconnect_cables to remove cables, or plan_external_endpoints to terminate incoming building cable drops on a patch panel.

Validate and register a custom hardware blueprint into the active catalog so unlisted equipment can be mounted. Pass the entire specification inside the top-level 'blueprint' object: 'blueprint.slug' must use lowercase kebab-case, ports may combine explicit 'ports[]' with repeating 'port_groups[]' macros whose coordinates fit strictly within 'blueprint.geometry' without overlapping, and 'slots[]' applies only when 'mount_type' is 'modular-carrier' whereas 'slot_compatibility' applies to 'sub-module'. Persists YAML to the local custom-catalog folder in stdio mode or session memory on remote servers, overwrites same-slug custom entries without touching mounted rack state or undo history, and returns status 'INVALID' instead of throwing on validation errors. Use only after search_catalog confirms hardware is unlisted; use mount_equipment instead to place an already registered blueprint into the rack.

Remove specific cables by identifier or strip all cables attached to a mounted device or modular carrier from the active rack, then re-evaluate PoE budgets and plug clearances. Supply a non-empty 'cable_ids' list, 'instance_id', or both to disconnect their union; 'instance_id' matches both 'from' and 'to' endpoints across a carrier and its child sub-modules while leaving external patch-panel drops intact, whereas omitting both or passing only an empty list returns status 'INVALID' with a PORT_NOT_FOUND issue and zero mutations. Valid calls push an undo snapshot, persist rack.yaml atomically, and return removed IDs, remaining cable count, and updated validation results, succeeding idempotently when targeted IDs are already absent. Use when rewiring ports while keeping hardware mounted; use connect_cables to add or replace cables, or modify_equipment with action 'remove' to delete a device and its cables.

Generate 2D elevation and wiring SVGs, a Markdown BOM, a binary 3D GLB scene, and parametric OpenSCAD or watertight STL 3D-print models for the active rack project. Omitting 'formats' exports all six types; 'carrier-scad' and 'carrier-stl' emit one file per mounted modular carrier, switch cradle, or printable cover panel and emit zero files when none are mounted, while 'output_dir' resolves relative paths within the project directory and creates missing folders. Local stdio execution writes deterministic filenames—elevation.svg, wiring-schematic.svg, BOM.md, rack-scene.glb, and <slug>.scad or <slug>.stl—overwriting same-named files in place, whereas hosted remote sessions stream in-memory HTTPS download URLs; neither mode mutates rack state or undo history. Use after validate_rack confirms a valid layout; use validate_rack instead for read-only validation and ASCII elevation inspection without generating export files.

Retrieve the complete hardware specification, millimeter port coordinates, electrical and PoE ratings, and carrier slot geometry for a single catalog blueprint. The 'slug' parameter requires a case-sensitive exact match in lowercase kebab-case vendor-model-variant format against the built-in or session custom catalog; partial substrings or uppercase characters do not match. Returns the full blueprint in one unpaginated payload with repeating port_groups pre-expanded into up to 256 flat ports[] entries, or returns status 'INVALID' with a BLUEPRINT_NOT_FOUND issue and candidate slugs instead of throwing. Use when you already know the target slug and need exact port_id or slot_id values for mount_equipment or connect_cables; use search_catalog instead to discover unknown slugs by criteria.

Initialize a new rack project and destructively reset the active rack.yaml state to an empty enclosure with the specified width standard, U height, and rail depth. Overwrites the current enclosure and clears all mounted devices, child sub-modules, cables, and external endpoints, while pushing the previous project state onto the in-memory undo stack for recovery via undo_redo. 'project_name' sets the title used in exported schematics and BOMs, 'rail_depth_mm' plus 'rear_clearance_mm' bounds total +Z chassis and rear plug depth before wall collision, and 'front_door_clearance_mm' is enforced only when 'enclosure_type' has a closed front door. Use when starting a rack design from scratch or changing enclosure dimensions; use validate_rack to inspect the current rack, or modify_equipment to move or remove individual devices.

Move, rename, or destructively remove an existing mounted device or child sub-module in the active rack, recalculate 3D cable splines, and re-run 5-stage validation. 'instance_id' resolves across top-level devices and carrier sub-modules, and required fields depend on 'action': 'move' updates 'u_position' and 'face' on rackmount gear or 'slot_id' and optional 'parent_carrier_id' across carriers for sub-modules with primary fields taking precedence over 'new_*' aliases, 'rename' updates or clears 'hostname', and 'remove' cascades to child sub-modules plus attached cables and external endpoints when 'remove_connected_cables' is true. Pushes the prior state onto the undo stack and updates rack.yaml atomically, or returns status 'INVALID' without mutating state when 'instance_id' or a target carrier is unknown. Use to update or delete a mounted instance; use mount_equipment to add new hardware, or disconnect_cables to remove cables while keeping devices mounted.

Mount a new hardware device instance onto a rack unit or into a modular carrier bay in the active rack.yaml project and run 5-stage validation. 'instance_id' must be unique across both top-level devices and nested sub-modules, 'blueprint_slug' must reference an existing catalog or custom slug, and placement uses two mutually exclusive modes: 'u_position' with optional 'face' where the device's full U span fits within 1..u_height, or 'parent_carrier_id' plus a compatible 'slot_id' for sub-modules. Precondition errors such as duplicate 'instance_id', unknown 'blueprint_slug', or missing carriers return status 'INVALID' without mutating state, whereas 3D collision or PoE issues persist the mount, push an undo snapshot, and return remediation_suggestions. Use to add a new device instance; use modify_equipment to move, rename, or remove an existing instance, or plan_external_endpoints for off-rack room cable drops.

Terminate external building or room cable drops onto the rear RJ45 ports of a mounted patch panel without consuming rack U slots, and optionally auto-create labeled Cat6A front patch cables to a mounted switch. 'groups[]' batch-generates drops first—with 'custom_labels[]' overriding numbered 'label_prefix' entries per index—followed by 'endpoints[]', allocating sequential free rear ports from 'start_port_number' and sequential free switch RJ45 ports from 'auto_connect_switch_start_port'. Setting 'clear_existing' destructively removes prior external drops on 'patch_panel_instance_id' and their front patch cables before allocation, while unmounted patch-panel or switch IDs return status 'INVALID' without mutating state. Use for off-rack building wiring entering the enclosure; never mount room endpoints via mount_equipment, and use connect_cables for purely internal rack-to-rack links.

Search and filter the local hardware catalog to discover compatible rackmount devices, modular carriers, and sub-modules before mounting. All supplied filters combine with logical AND: 'form_factor' and its alias 'mount_type' accept width shorthands '10inch', '19inch', and '6inch' that match both direct rackmount gear and modular carriers, 'accepted_slot_type' matches both carrier bays and compatible sub-modules, and 'max_depth_mm' bounds chassis depth excluding plug clearance. Returns all matches from the bounded catalog in one unpaginated response sorted in deterministic registration order, with built-in blueprints followed by custom blueprints. Call with no arguments to list the full catalog; use get_device_blueprint to inspect expanded port coordinates for a known slug, or define_custom_blueprint to register unlisted hardware.

Traverse the per-project in-memory history ring buffer of up to 50 snapshots to revert the latest rack mutation or reapply a reverted mutation, updating rack.yaml atomically. Setting 'action' to 'undo' steps backward across rack-state mutations—excluding catalog-only define_custom_blueprint calls and read-only tools—and pushes the displaced state onto the redo stack, whereas 'redo' is available only immediately after 'undo' because any new rack mutation flushes the redo stack. Calling either action when its target stack is empty is a safe no-op returning applied=false without throwing. Use to roll back an unintended batch change or accidental init_rack reset; use modify_equipment or disconnect_cables instead to edit specific items without reverting intermediate steps.

Inspect the active rack.yaml state and run all 5 deterministic validation stages covering mechanical bounds, 3D depth and plug clearances, PoE and power budgets, cable compatibility, and thermal limits. Takes no parameters, performs zero state or undo-stack mutations, and returns the ASCII front and rear elevation diagram, power utilization summary, and all diagnostic issues with remediation_suggestions. Sets status to 'INVALID' instead of throwing whenever any validation ERROR is present. Use to inspect currently mounted equipment or verify zero errors before exporting; use export_deliverables instead to generate SVG, BOM, GLB, or 3D-print files.
