  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name weatherlink-mcp.

  • Pass
    Lists tools

    tools/list returned 7 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 57 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 57 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.

    Every tool description is at least 20 characters.

  • Pass

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    9 of 9 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A 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.

Capabilities

Tools 7

weatherlink_get_current_conditions

Get the latest weather observation for one station, per sensor (for example temperature, humidity, wind and rain). How recent the record is depends on the access level: Pro+ gives the most recent record, Pro the most recent 5-minute record. WeatherLink v2: GET /v2/current/{station-id}.

Discovered
weatherlink_get_et_report

Get the evapotranspiration (ET) data for one WeatherLink Live station. Only WeatherLink Live stations report ET. WeatherLink v2: GET /v2/report/et/{station-id}.

Discovered
weatherlink_get_historic_data

Get historic weather records for one station between two Unix times. The window can be at most 24 hours (86400 seconds). Each record's timestamp is the END of its recording interval. Access depends on the subscription level (Basic has no historic data). WeatherLink v2: GET /v2/historic/{station-id}.

Discovered
weatherlink_get_sensor_activity

Get the last reporting time of sensors, to find sensors that stopped reporting. Leave sensor_ids empty for every sensor. WeatherLink v2: GET /v2/sensor-activity (or /v2/sensor-activity/{sensor-ids}).

Discovered
weatherlink_list_nodes

List the nodes your API Key can access, with their metadata. WeatherLink v2: GET /v2/nodes (or /v2/nodes/{node-ids}).

Discovered
weatherlink_list_sensors

List the sensors your API Key can access, with their metadata. WeatherLink v2: GET /v2/sensors (or /v2/sensors/{sensor-ids}).

Discovered
weatherlink_list_stations

List the weather stations your API Key can access, with their metadata. Start here to find a station id. WeatherLink v2: GET /v2/stations (or /v2/stations/{station-ids}).
