Stability & Change Management30
- Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_power ¿Puedo bajar la potencia contratada? ~200
Decide whether the user can lower their contracted power (potencia contratada) and how much they would save per year. Compares the power they pay for against the maximum their meter actually recorded, leaving a safety margin, and works out the payback period against the one-off fee for changing it. This is the single most common way to cut a Spanish electricity bill without changing supplier.
| Name | Type | Req | Description |
|---|---|---|---|
| file_path | string | – | Absolute path to the invoice file on this machine (PDF, PNG, JPG, WEBP). The file is read locally and never uploaded anywhere. |
| invoice | object | – | The `invoice` object returned by a previous read_invoice call. Pass this to analyse the same invoice again without re-reading the file, which is much faster. |
| qr_url | string | – | An already-decoded CNMC comparator URL (https://comparador.cnmc.gob.es/comparador/QRE?...). Use this when the QR has been read elsewhere. |
No output schema declared.
No examples provided.
explain_concept Explicar un concepto de la factura ~209
Explain one concept of a Spanish electricity bill in plain Spanish, ready to relay to the user. Pass an invoice as well and the explanation comes back with that invoice’s own figures for the fields involved. Call list_concepts, or read the cnmc://glossary resource, to see the available concepts.
| Name | Type | Req | Description |
|---|---|---|---|
| concept | string | yes | The concept to explain, for example termino_potencia or impuesto_electricidad. |
| file_path | string | – | Absolute path to the invoice file on this machine (PDF, PNG, JPG, WEBP). The file is read locally and never uploaded anywhere. |
| invoice | object | – | The `invoice` object returned by a previous read_invoice call. Pass this to analyse the same invoice again without re-reading the file, which is much faster. |
| qr_url | string | – | An already-decoded CNMC comparator URL (https://comparador.cnmc.gob.es/comparador/QRE?...). Use this when the QR has been read elsewhere. |
No output schema declared.
No examples provided.
list_concepts Listar conceptos explicables ~30
List every invoice concept explain_concept can describe, with its id and Spanish title. Takes no arguments.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
read_invoice Leer factura de la luz ~214
Read a Spanish electricity invoice and return everything it says, in structured form. Decodes the CNMC QR code from a PDF or image on this machine, then returns the supply point, the contract and what it means, the billing period, contracted and demanded power, consumption, prices, the amounts billed, an averaged monthly estimate, a Spanish summary you can relay to the user, and warnings about anything uncertain. Start here for any question about an invoice.
| Name | Type | Req | Description |
|---|---|---|---|
| file_path | string | – | Absolute path to the invoice file on this machine (PDF, PNG, JPG, WEBP). The file is read locally and never uploaded anywhere. |
| invoice | object | – | The `invoice` object returned by a previous read_invoice call. Pass this to analyse the same invoice again without re-reading the file, which is much faster. |
| qr_url | string | – | An already-decoded CNMC comparator URL (https://comparador.cnmc.gob.es/comparador/QRE?...). Use this when the QR has been read elsewhere. |
No output schema declared.
No examples provided.
simulate_power_change Simular un cambio de potencia ~223
Work out the annual saving for a specific pair of contracted powers, rather than the recommended one. Use it to answer "and if I set it to 3 kW?". Warns when the proposal is below the power the meter actually recorded, which would trip the breaker.
| Name | Type | Req | Description |
|---|---|---|---|
| file_path | string | – | Absolute path to the invoice file on this machine (PDF, PNG, JPG, WEBP). The file is read locally and never uploaded anywhere. |
| invoice | object | – | The `invoice` object returned by a previous read_invoice call. Pass this to analyse the same invoice again without re-reading the file, which is much faster. |
| p1_kw | number | yes | Proposed contracted power for P1 (punta), in kW. |
| p2_kw | number | yes | Proposed contracted power for P2 (valle), in kW. |
| qr_url | string | – | An already-decoded CNMC comparator URL (https://comparador.cnmc.gob.es/comparador/QRE?...). Use this when the QR has been read elsewhere. |
