askacharge.com MCP server

Let an AI agent operate a network of EV charge points.

askacharge.com is a CSMS — a Charging Station Management System — for electric vehicle charging: OCPP 1.6J and 2.0.1 to the hardware, tariffs and billing, QR and RFID driver payments, OCPI 2.2 roaming between operators, and fiscal invoicing. This repository documents its remote MCP server, which exposes that platform to any Model Context Protocol client.

Nothing to install. It is a hosted endpoint:

https://askacharge.com/askacharge/api/mcp

Transport is JSON-RPC 2.0 over HTTP POST (streamable-http). Protocol versions accepted: 2025-06-18, 2025-03-26, 2024-11-05. GET returns 405 on purpose — there is no SSE stream.

Why this exists

Charge point operators spend their day on questions an agent can answer directly: which chargers are offline right now, what did site X earn last month, is it cheap enough to charge at this hour, reboot the one that stopped responding. The REST API has always been able to do that. MCP is what makes it usable by an agent without anyone writing an integration first — the value is not the protocol, it is the description of when to use each tool and what happens if you get it wrong.

Authentication

One header, the brand's API key, created from the panel under API keys:

Authorization: Bearer ask_live_...

X-Api-Key: ask_live_... works too.

The key's scopes decide which tools you can see. A read-only key never gets shown askacharge_parar_carga. A key restricted to one location (commands:write@hotel-madrid) sees the command tools and receives a 403 when it aims them at a charger somewhere else. A key belongs to one brand and reaches only that brand's data.

The 21 tools

Read

Tool	What it answers
`askacharge_listar_cargadores`	Every charge point with OCPP status, location and last contact
`askacharge_ver_cargador`	One charger in detail: connectors, power, access mode, status
`askacharge_estado_en_vivo`	Right now: chargers connected, sessions running, power being drawn
`askacharge_resumen`	Period KPIs — energy, revenue, net margin, sessions, customers
`askacharge_listar_sesiones`	Charging session history with energy, revenue and cost
`askacharge_listar_incidencias`	Open faults per charger
`askacharge_listar_tarifas`	Tariff groups: per kWh, per hour, per session, PVPC or free
`askacharge_precio_pvpc_hoy`	Today's hour-by-hour Spanish PVPC electricity price
`askacharge_listar_clientes`	Fleet customers with their tariff and monthly consumption
`askacharge_limites_de_potencia`	kW ceiling per location and load-balancing strategy
`askacharge_traza_de_actividad`	What the brand's API keys did: writes and rejected attempts

OCPP commands — these act on physical hardware

Tool	What it does
`askacharge_arrancar_carga`	Remote start (OCPP `RemoteStartTransaction`)
`askacharge_parar_carga`	Remote stop (OCPP `RemoteStopTransaction`) — cuts a live session
`askacharge_reiniciar_cargador`	Reboot, soft or hard (OCPP `Reset`)
`askacharge_cambiar_disponibilidad`	Put a charger in or out of service (OCPP `ChangeAvailability`)
`askacharge_diagnosticos`	Ask the charger to upload its diagnostics file (OCPP `GetDiagnostics`)

Write

Tool	What it does
`askacharge_crear_cargador`	Register a charge point
`askacharge_crear_tarifa`	Create a tariff group (`per_kwh`, `per_hour`, `per_session`, `pvpc_margin`, `free`…)
`askacharge_crear_cliente`	Register a fleet customer
`askacharge_crear_tag_rfid`	Authorise an RFID tag on the brand

Escape hatch

Tool	What it does
`askacharge_llamar_api`	Call any of the platform's 438 API operations, under the same permission checks

It does not reimplement the product

Every tool runs against askacharge.com's own REST API with the same key, so it passes through the same scopes, the same audit trail, the same rate limit and the same idempotency handling. If a tool could ever do something the API forbids, that is a bug in the server, not a feature. The envelope itself is not what gets logged — the concrete operation it triggered is.

Using it

Claude Code

claude mcp add --transport http askacharge https://askacharge.com/askacharge/api/mcp \
  --header "Authorization: Bearer ask_live_..."

Clients that take a JSON config

{
  "mcpServers": {
    "askacharge": {
      "type": "http",
      "url": "https://askacharge.com/askacharge/api/mcp",
      "headers": { "Authorization": "Bearer ask_live_..." }
    }
  }
}

Raw, to check it is alive

curl -s -X POST https://askacharge.com/askacharge/api/mcp \
  -H "Authorization: Bearer ask_live_..." \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Without a key you get a JSON-RPC error telling you so, which is also a fine way to confirm the endpoint is reachable.

Getting a key

Create an account at askacharge.com — 30-day trial, no card — then API keys in the panel. Pricing is a flat €20/month with unlimited chargers and no software commission per session; the whole list, including what does carry a percentage, is at askacharge.com/askacharge/en/pricing.html.

Honest limits

Tool names and descriptions are in Spanish. The platform's first market is Spain and the Basque Country. Models handle it without trouble, but you should know before you wire it in.
Scoping a key by location restricts what it can act on, not what it can read. A listing still returns the whole brand. This is documented behaviour, not an oversight.
There is no separate sandbox. To try things without consequences, create a brand in trial mode.
No SSE stream. Request/response only.

En español

Servidor MCP remoto de askacharge.com, la plataforma de gestión de cargadores de vehículo eléctrico (CSMS) con OCPP 1.6J/2.0.1, roaming OCPI 2.2, pago por QR y facturación fiscal (Verifactu y TicketBAI/Batuz).

Endpoint: https://askacharge.com/askacharge/api/mcp. No hay nada que instalar. Se autentica con la API key de la marca en Authorization: Bearer, y los scopes de esa key deciden qué herramientas se ven: una key de solo lectura nunca ve las de parar una carga, y una acotada por ubicación (commands:write@hotel-madrid) recibe un 403 si apunta a un cargador de otra sede.

Son 21 herramientas —cargadores, estado en vivo, sesiones, tarifas, PVPC, clientes, límites de potencia, comandos OCPP y altas— más askacharge_llamar_api, que abre las 438 operaciones de la API con el mismo control de permisos. Ninguna reimplementa lógica de negocio: todas se ejecutan contra la propia API REST, con los mismos scopes, la misma traza y el mismo límite de uso.
