Input parameters: - `country` (string, required): 2-letter lowercase country code, e.g. "de", "fr", "es". - `time_step` (string): Granularity of the capacity series. Default "yearly". ### `renewable_share` (~296 tokens) Renewable share of a country's electricity LOAD, as a percent — how much of demand wind, solar, hydro and biomass are covering, now or over a past date range. Answers "what share of Germany's electricity is renewable right now", "how renewable was France's grid in July", "which days last month did renewables cover most of the load". Accepts a country NAME ("Germany") or 2-letter code, or "eu"/"all" for the EU aggregate. Returns the latest MEASURED reading with its timestamp, a min/avg/max summary for the window, and a per-day breakdown; 15-minute readings are included for windows of 3 days or less. Values are percent OF LOAD and legitimately exceed 100 when a country generates more renewable power than it consumes and exports the surplus. Measured settled data, not a forecast. Keyless.

Energy Charts scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the Energy Charts MCP server expose? Energy Charts exposes 6 tools: generation_mix, public_power, electricity_price, total_power, installed_power, renewable_share. Their descriptions and schemas cost roughly 968 tokens of context every time the server is loaded. ### Is the Energy Charts MCP server still maintained? Energy Charts is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ### What licence is the Energy Charts MCP server under? Energy Charts declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls. ### What did VerifyMCP test on the Energy Charts MCP server? VerifyMCP ran 16 checks on Energy Charts, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested.
