Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 321 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name dryos.

  • Pass
    Lists tools

    tools/list returned 5 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 321 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 321 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 26 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-09-18T01:07:52.067828Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 5

column_values

The distinct values of one text column, most rows first — what a filter can be. Args: slug: The stream. column: A text column from describe_stream (not the entity — use find_entities). where: Filters as `column=value`, the same as query_stream's. search: `column:text`, a case-insensitive substring. limit: At most this many (1–500).

Discovered
describe_stream

One stream in full: every column, the primary key, the source and its health. Also what changed in the collector recently — a change in the collector is a change in the data, and a step in a series may be one. Args: slug: The stream, e.g. ercot-realtime-lmp (list_streams names them).

Discovered
find_entities

Look up the nodes, zones, stations or fuels in a stream, with how far back each goes. Use it before query_stream: names are verbatim and never to be guessed. `facets` counts the entities by type. Args: slug: The stream. search: Case-insensitive substring of the entity name ("HOUSTON", "HB_", "KAUS"). entity_type: Only one type — HUB, LOAD_ZONE, RESOURCE_NODE, INTERFACE… limit: At most this many (1–2000).

Discovered
list_streams

Every stream Dryos collects, with its entity column and headline measure. Args: domain: Energy, Weather or Property. operator: A grid operator — ERCOT, MISO, PJM, SPP, CAISO, NYISO or ISO-NE. search: A word matched against the slug, name and tagline ("lmp", "wind", "permits").

Discovered
query_stream

Read rows from a stream — raw (newest first), each entity's newest, or a rollup. The result carries `restUrl`: this same request as a plain GET on the public REST API, ready to put in an app. Args: slug: The stream. node: The entity, whatever the stream calls it (node, zone, station, fuel). System-level streams have none. start: Inclusive, ISO-8601 or relative to now (-24h, -7d). UTC. end: Exclusive, same forms. interval: Bucket size — 5m, 15m, 1h, 1d, 7d, or all for one bucket. Absent means raw rows. agg: How a bucket is reduced. by: What a rollup splits by: a text column, or none for one series. Default the entity. where: Filters as column=value on text columns. Repeat a column for OR. search: column:text, a case-insensitive substring. vintages: latest is each interval's newest forecast; all keeps every publication. stamp: noon labels a daily bucket at noon UTC so its date reads right in US zones. newest: One reading per entity — each one's most recent interval, so "the price at every hub right now" is one call. Not with interval. limit: At most this many rows (1–2000).
