## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: cheapest_window (idempotentHint); list_zones (idempotentHint); get_carbon (idempotentHint); …
- pass `tools.token_cost`: about 953 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 953 tokens to load them all
- tool set hash: 254246f50f13a062b0f190b0bfa12bb6
- badge: [![protogrid quality](https://protogrid.dev/badge/com.voltcast/voltcast.svg)](https://protogrid.dev/servers/com.voltcast/voltcast)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `cheapest_window`: Rank household action windows by cost using current Voltcast curves and optional user-supplied variable tariff inputs. Experimental carbon/balanced modes use a disclosed trailing historical production-mix profile—not a forward carbon forecast—and support no emissions-reduction claim.
- `get_carbon`: Carbon intensity (gCO2eq/kWh) and green score (0-100 low-carbon share) derived from the live generation mix.
- `get_forecast`: Probabilistic price forecast up to 7 days ahead. Returns the P50 curve and any uncertainty bands included in the connected account. Accuracy is published daily at voltcast.com/accuracy.
- `get_prices`: Day-ahead electricity prices in each zone's native currency and native market resolution. Connect an existing Voltcast account to access account-scoped data.
- `get_realtime_prices`: Explicitly labeled real-time market prices (currently WEIM), kept separate from day-ahead curves. Requires an API key.
- `get_renewables`: Day-ahead wind and solar generation forecasts: the TSO official forecast and Voltcast model with uncertainty bands, realized generation, and disclosed head-to-head verification. Requires the corresponding existing account entitlement.
- `list_zones`: List all supported European bidding zones with codes, names, and capabilities. No auth required.
