How do I install the wiring diagram mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `VOLTPLAN_API_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Wiring Diagram MCP Server?

MCP server that generates 12V/24V/48V wiring diagrams and sizes wires, fuses, batteries, solar arrays, and inverters for campers, boats, and off-grid systems.

What the server does

An MCP server that gives Claude (or any MCP-compatible AI) domain expertise in 12V / 24V / 48V electrical systems — sizing the bank, picking the wire gauge, recommending the fuse, and generating a complete wiring diagram. For boats, campers, vans, and off-grid builds.

Issues, ideas, and pull requests welcome on GitHub.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
calculate_power_budget	Daily energy draw from a list of loads (Wh, Ah, peak power)
calculate_battery_bank	Bank size for given consumption + autonomy + DoD
calculate_battery_config	Series/parallel arrangement to hit a target voltage and capacity
calculate_solar_size	Panel wattage to recharge daily, accounting for sun hours and losses
calculate_wire_gauge	AWG / mm² for current and run length, with fuse recommendation
calculate_inverter_size	Inverter wattage for AC loads, with surge headroom and DC current draw
calculate_charging_time	Time from X% to Y% SoC, with bulk and absorption phases
generate_wiring_diagram	Complete schematic as SVG or PNG, auto-fused and protected
list_component_types	Component reference and example configs for diagram building
