Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Check how fresh the data is for each of the 10 sources. Returns a JSON array of sources with latest_observation timestamp, age_seconds, and a status classification: "fresh" (<1h), "stale" (<24h), or "offline" (>24h). Use this to check if a specific data source is currently delivering data.
This tool takes no arguments.
This tool isn't marked read-only, so it may change something on the server or in an account you connected.

}Get latest environmental readings near a location. Args: lat: Latitude in WGS84 (e.g. 51.92 for Rotterdam) lon: Longitude in WGS84 (e.g. 4.47 for Rotterdam) radius_km: Search radius in kilometers (default 10, max 50) parameter: Optional filter by parameter name or alias (e.g. "pm2_5", "temperature", "pm25", "no2"). Use get_parameters() to see all valid names and aliases. limit: Maximum number of readings to return (default 100, max 500) Returns JSON with readings array. Each reading includes parameter, value, unit, timestamp, station_name, coordinates, source, and source_attribution.

| lat* | number | |

}List all 35 available environmental parameters with units and aliases. Returns a JSON array of parameters. Each entry includes name, display_name, unit (UCUM), definition_url (CF Conventions), and aliases (alternative names you can use in get_latest_readings). No FROST query needed — this is an in-memory lookup.

}List all environmental data sources with station counts and geographic coverage. Returns a JSON array of sources, each with name, station_count, datastream_count, and source_attribution fields.

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 14, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
