The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
browse_business_category unknown never probed
Lists public directory entries in one business category, optionally narrowed to a locality/postcode/canton. Use search_swiss_directory instead for a free-text query.
{ "type": "object", "required": [ "category" ], "properties": { "lang": { "enum": [ "de", "fr", "it", "en" ], "type": "string", "description": "Response language: de, fr, it, or en. Defaults to de." }, "limit": { "type": "integer", "default": 10, "maximum": 20, "minimum": 1, "description": "Maximum number of results, 1-20." }, "category": { "type": "string", "maxLength": 200, "minLength": 1, "description": "The business category slug (e.g. \"restaurant\", \"coiffeur\", \"sanitaer\"). Valid slugs are the slug values in categories, as returned by get_directory_entry, or a top-level group slug such as \"bau-handwerk\"." }, "location": { "type": "string", "maxLength": 200, "description": "Locality, postcode, or canton (e.g. \"Baden\", \"5400\", \"ZH\") to narrow the category to. Always put a place name here." } }, "additionalProperties": false }arguments 37 linesreverse_phone_lookup unknown never probed
Looks up the public directory entry (or entries) associated with a Swiss phone number. Accepts national ("079 123 45 67"), E.164 ("+41791234567"), or compact notation. Returns an empty result list when the number has no findable public listing.
{ "type": "object", "required": [ "phone_number" ], "properties": { "lang": { "enum": [ "de", "fr", "it", "en" ], "type": "string", "description": "Response language: de, fr, it, or en. Defaults to de." }, "phone_number": { "type": "string", "maxLength": 40, "minLength": 1, "description": "The phone number to look up, in any common Swiss notation (national, E.164, or compact)." } }, "additionalProperties": false }arguments 25 linessearch_swiss_directory unknown never probed
Full-text search over the Swiss public phone/business directory (1820.ch). Matches ALL words in query, so a short keyword works best; put any place name in location, not query. For "business type X in place Y", browse_business_category with a category slug is an alternative. Use get_directory_entry for phone numbers and opening hours of a specific result.
{ "type": "object", "required": [ "query" ], "properties": { "lang": { "enum": [ "de", "fr", "it", "en" ], "type": "string", "description": "Response language: de, fr, it, or en. Defaults to de." }, "limit": { "type": "integer", "default": 10, "maximum": 20, "minimum": 1, "description": "Maximum number of results, 1-20." }, "query": { "type": "string", "maxLength": 200, "minLength": 1, "description": "One short keyword: a person's or company name, or ONE business type (e.g. \"Müller\", \"Migros\", \"Coiffeur\"). Every word must match, so no sentences or extra adjectives. Never put a place name here — use location instead." }, "location": { "type": "string", "maxLength": 200, "description": "Locality, postcode, or canton (e.g. \"Baden\", \"5400\", \"ZH\") to narrow the search. Always put a place name here, never in query." }, "entry_type": { "enum": [ "person", "business", "all" ], "type": "string", "default": "all", "description": "Restrict results to person, business, or all entries." } }, "additionalProperties": false }arguments 47 linesget_directory_entry unknown never probed
Fetches the full public detail for one directory entry by its entry_id (public_id), including phone numbers, opening hours, and links when the entry has them. Use get_directory_entry for phone numbers and opening hours; use search_swiss_directory or browse_business_category to find an entry_id first.
{ "type": "object", "required": [ "entry_id" ], "properties": { "lang": { "enum": [ "de", "fr", "it", "en" ], "type": "string", "description": "Response language: de, fr, it, or en. Defaults to de." }, "entry_id": { "type": "string", "maxLength": 32, "minLength": 1, "description": "The entry's public_id, as returned by search_swiss_directory, browse_business_category, or reverse_phone_lookup." } }, "additionalProperties": false }arguments 25 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
