Connect VoltPlan Wiring Diagrams and your agent gets 9 tools, among them calculate_battery_bank, calculate_battery_config, calculate_charging_time. It answers at https://mcp.voltplan.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 21 October 2026, succeeded.
Generate 12V/24V/48V wiring diagrams and size wires, fuses, batteries, solar, and inverters.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
calculate_battery_bank | Calculate the recommended battery bank size based on daily energy consumption. Accounts for days of autonomy (how many days without charging) and depth of discharge. Returns required capacity, number of batteries, and wiring configuration. Inputs: dailyConsumptionWh, daysOfAutonomy, depthOfDischargePercent, systemVoltage, singleBatteryAh, singleBatteryVoltage |
calculate_battery_config | Determine how to arrange batteries in series and/or parallel to achieve a target voltage and capacity. Returns the number of batteries needed, the wiring configuration (e.g. 2S3P), and step-by-step wiring instructions. Inputs: targetVoltage, targetCapacityAh, singleBatteryVoltage, singleBatteryAh |
calculate_charging_time | Estimate how long it takes to charge a battery bank from a given state of charge to a target level. Accounts for the bulk charging phase (constant current, up to ~80% SoC) and the slower absorption phase (tapering current, 80-100% SoC). Wor Inputs: batteryCapacityAh, batteryVoltage, currentStateOfChargePercent, targetStateOfChargePercent, chargePowerWatts, chargeCurrentAmps |
calculate_inverter_size | Calculate the recommended inverter size for running AC loads from a DC battery system. Accounts for continuous power, startup surge power (motors typically surge 2-3x), and includes a 25% headroom for the continuous rating. Returns the reco Inputs: systemVoltage, loads |
calculate_power_budget | Calculate total daily energy consumption from a list of electrical loads. Each load specifies its power draw, how many hours per day it runs, and quantity. Returns total daily energy (Wh and Ah), peak power draw, and average power. This is Inputs: systemVoltage, loads |
calculate_solar_size | Calculate the required solar panel wattage to cover daily energy consumption. Accounts for peak sun hours at the location and system efficiency losses (MPPT conversion, wiring, temperature derating). Returns required wattage and common pane Inputs: dailyConsumptionWh, peakSunHours, systemEfficiency |
calculate_wire_gauge | Calculate the recommended wire gauge / cable cross-section for a DC circuit. Considers both ampacity (current carrying capacity) and voltage drop to recommend the optimal cable size. Also returns total resistance, power loss, and a fuse rec Inputs: voltage, current, power, cableLengthM, maxVoltageDropPercent, temperatureCelsius |
generate_wiring_diagram | Generate an electrical wiring diagram for campers, boats, or off-grid setups. Returns a complete schematic with batteries, chargers, protection components, and loads. Protection components (shunt, main switch, low-voltage cutoff) are auto-g Inputs: systemName, batteries, loads, chargers, format |
list_component_types | List all available component types and example configurations for building wiring diagrams. Use this to understand what parameters are needed before calling generate_wiring_diagram. |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.voltplan.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.yuzu-hub. Endpoint host: mcp.voltplan.app. ARD identifier: urn:air:io.github.yuzu-hub:mcp:wiring-diagram-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
