Running the server is a container command; getting the APsystems App ID and Secret means writing to their support team and explaining what you want the data for. Once you have them the coverage is genuinely deep — per-channel inverter telemetry and minutely ECU data, not just a daily total — so it rewards a system with more than one string.
A Go server wrapping the APsystems OpenAPI, so a client can read your solar installation's monitoring data: system-level energy totals, per-ECU and per-inverter telemetry, meter flows and battery state. It handles the APsystems HMAC-SHA256 signature protocol for you, retries on rate limits, and can optionally serve a dark-themed web dashboard alongside the MCP endpoint.
- 16 tools covering the APsystems API endpoints
- System: `get_system_details`, `get_system_summary` for today/month/year/lifetime kWh, `get_system_energy` by period, `get_inverters`, `get_meters`
- ECUs: `get_ecu_summary` and `get_ecu_energy`, which supports minutely telemetry
- Inverters: `get_inverter_summary` per channel, `get_inverter_energy` with DC power, current, voltage and AC telemetry, `get_inverter_batch_energy` for every inverter under one ECU in a single call
- Meters: `get_meter_summary` for consumed, exported, imported and produced totals, plus `get_meter_period`
- Storage: `get_storage_latest` for live state of charge and charge/discharge power, `get_storage_summary`, `get_storage_period`
- An optional web dashboard with Chart.js energy visualisations, enabled with `APS_DASHBOARD=true`
APsystems OpenAPI credentials — `APS_APP_ID`, `APS_APP_SECRET` — plus `APS_SYS_ID`, your system ID from the EMA app under Settings → Account Details. Getting API access means emailing APsystems support with who you are and what you plan to do, which is the slow step. Run it with Go from source, or use the published container `docker.io/mehdijrgr/apsystems-mcp-server`. Transport is stdio by default; set `APS_MCP_TRANSPORT=sse` with `APS_MCP_SSE_ADDR` to serve remote clients over HTTP instead.
