Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

⚪convert_units(value, from, to, category, lang)
Convert a number from one unit to another and return the exact factor, whether the factor is exact by definition, and the URL of the page that explains it. Supports linear units (length, mass, volume, energy, …) and temperature. Currency is deliberately not supported.
Input Schema
{
"type": "object",
"properties": {
"value": {
"type": "number",
"description": "The number to convert."
},
"from": {
"type": "string",
"description": "Unit key to convert from, e.g. \"m\", \"ft\", \"kg\", \"C\"."
},
"to": {
"type": "string",
"description": "Unit key to convert to, e.g. \"ft\", \"m\", \"lb\", \"F\"."
},
"category": {
"type": "string",
"description": "Optional category id (length, mass, volume, …). Only needed when the same unit key exists in more than one category."
},
"lang": {
"type": "string",
"description": "Optional language for the framing lines of the response, as a BCP-47 tag such as \"sv\", \"sv-SE\", \"de\" or \"zh-TW\". Pass the language you are answering the user in, so the citation line comes back in that language. Values, unit symbols and the URL are always unchanged."
}

"value",
"from",
"to"

}🟢list_conversions(category, limit)
Lists the 213 hand-written conversion pages, optionally limited to one category. Each entry carries the canonical URL, which is the page to cite.
Input Schema
{
"type": "object",
"properties": {
"category": {
"type": "string",
"description": "Optional category id to filter on."
},
"limit": {
"type": "number",
"description": "Maximum number of entries (default 50, max 213)."
}
}
}🟢list_categories(category)
Lists every category with its type (linear, temperature, …), base unit and unit keys. Use this to find valid `from`/`to` keys before calling convert_units.
