Category Data and Analytics
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-energy-charts). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 3 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1022 tokens (~170/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
electricity_price ~117
Day-ahead spot electricity prices for a bidding zone over a date range. Returns {unix_seconds, price, unit}; the price array is timestamp-aligned to unix_seconds. Prices in EUR/MWh.
| Name | Type | Req | Description |
|---|---|---|---|
| bzn | string | yes | Bidding-zone code, e.g. "DE-LU", "FR", "AT", "ES". |
| end | string | – | Optional end date, YYYY-MM-DD. Defaults to today. |
| start | string | – | Optional start date, YYYY-MM-DD. Defaults to 7 days ago. |
No output schema declared.
No examples provided.
generation_mix ~195
The CURRENT ELECTRICITY GENERATION MIX BY FUEL for a European country — how much power is coming from solar, wind, nuclear, gas, coal, hydro, biomass right now, with each fuel's MW and percentage share. Answers "what is Germany's generation mix", "how much of France's electricity is nuclear", "Germany power generation by source", "what fuels are generating electricity in <country>". Accepts a country NAME ("Germany", "France") or 2-letter code. Also returns renewable vs fossil vs nuclear totals. Source: Fraunhofer ISE energy-charts, keyless.
| Name | Type | Req | Description |
|---|---|---|---|
| at | string | – | Optional date YYYY-MM-DD for a historical mix (defaults to the latest available data). |
