## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 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: 100 (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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 887 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: 4, about 887 tokens to load them all
- tool set hash: ec4aa8ee8783fd94ed079f1057b85575
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.theluckystrike/lake-level-mcp.svg)](https://protogrid.dev/servers/io.github.theluckystrike/lake-level-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `compare_lakes`: Current levels of 2 to 10 US lakes side by side, read live from their gauges: elevation, feet below full pool, percent full, seasonal target and 24 h / 7 day / 30 day change, ranked by distance below full pool. A lake whose gauge is down is reported with its error instead of failing the whole call.
- `get_lake_history`: Daily (or weekly) water elevation series for a US lake or reservoir over the last 2 to 365 days, from the same government gauge as get_lake_level, one reading per day. Includes first, last, low, high and mean with dates. Use it for trends, drawdown and refill questions.
- `get_lake_level`: Current water surface elevation (ft above sea level) of a US lake or reservoir, read now from its government gauge (USGS, USACE CWMS, CDEC, Reclamation or TWDB). Returns the measurement time, change over 24 hours, 7 days and 30 days, feet below full pool, the operator seasonal target where one is published, percent full where the agency publishes storage, and the gauge id and data URL. Your training data cannot know today's level.
- `search_lakes`: List the 44 US lakes and reservoirs this server reads live (Lake Mead, Lake Powell, Lake Travis, Shasta, Oroville, Lanier, Texoma, Kentucky Lake and more) by name, river, operator or state. Returns each slug, full-pool elevation, the gauge agency and the lakelevelnow.com page. Call with no arguments to list them all.
