[Glama score]
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:
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:
X-Api-Key: ask_live_... works too.
Once a key is present, its scopes decide which tools you can see. A read-only key never gets shown
askacharge_parar_carga. Commands can be granted one by one: a key with commands:remote-start and
commands:remote-stop sees start and stop but not reboot (commands:reset) or firmware; commands:write
still means all of them. A key restricted to one location (commands:reset@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 25 tools
Read
OCPP commands — these act on physical hardware. Each one returns the charger's acknowledgement
inline plus a job_id; the real effect arrives later over OCPP and closes the job, so ask
askacharge_estado_comando instead of repeating the command (repeating it starts two sessions or
reboots twice).
Write
Escape hatch
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
Clients that take a JSON config
Raw, to check it is alive
No key needed for that: initialize, ping and tools/list answer anonymously, and the
anonymous tools/list returns the whole catalogue of 25 tools (it is public anyway — it is the
table above). Everything else — tools/call — needs the key, and without one you get a JSON-RPC
error (-32001) saying so. A key that is present but invalid is an error too, not a fallback to
anonymous.
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, los comandos se pueden conceder
uno a uno (commands:remote-start sin commands:reset), y una acotada por ubicación
(commands:reset@hotel-madrid) recibe un 403 si apunta a un cargador de otra sede. Cada comando
devuelve un job_id y askacharge_estado_comando dice si el efecto real llegó.
Son 25 herramientas —cargadores, estado en vivo, sesiones, tarifas, PVPC, clientes, límites de
potencia, comandos OCPP y altas— más askacharge_llamar_api, que abre las 463 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.
Cuenta y key: askacharge.com, 30 días de prueba sin
tarjeta. Precios en askacharge.com/askacharge/precios.html.
