Overview

AI-generated overview

Lets an assistant search the Swiss public phone and business directory, browse business categories, and look up the owner of a Swiss phone number.

What you can do
It provides four tools over the public 1820.ch Swiss directory. search_swiss_directory runs full-text searches matching all words in a query, with place names given separately. browse_business_category lists entries in a business category, optionally narrowed by locality, postcode or canton. get_directory_entry returns full public details for one entry, including phone numbers, opening hours and links. reverse_phone_lookup finds the public listing or listings tied to a Swiss phone number in national, E.164 or compact form.
When to use it
Useful when an assistant needs to find a Swiss business or person's public listing, check opening hours or contact details, or identify who a Swiss phone number belongs to. It suits directory-style lookups rather than general web search.
Requirements
A remote MCP endpoint at mcp.1820.ch over streamable HTTP; no package installation, account, API key or environment variable is declared. Network access to the endpoint is needed.
Before you install
Reverse phone lookup sends the number to a third-party directory service, and results are limited to publicly listed numbers. Directory data may be incomplete or out of date, so verify contact details before relying on them.

Installation

In SourceWeft

  1. Open 1820.ch – Telefonbuch Schweiz in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ch.1820%2Ftelefonbuch/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

4

browse_business_category

Browse a business category

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.

Parameterslanglimitcategoryrequiredlocation

get_directory_entry

Get a directory entry

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.

Parameterslangentry_idrequired

reverse_phone_lookup

Reverse phone lookup

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.

Parameterslangphone_numberrequired

search_swiss_directory

Search the Swiss directory

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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
