Overview

AI-generated overview

A remote MCP server about the Dutch word "tachtien" (uncountably many): look up the word, get examples and mentions, and rewrite vague amounts as tachtien.

What you can do
  • Look up the word: syllables, part of speech, IPA, definition and origin
  • Get example dialogues, all of them or one at random
  • List external mentions from Twitter, press or Cityguys with title, source and URL
  • Rewrite a text so vague large amounts and estimates of 50 or more become tachtien, with the replacement count and positions
  • Judge whether a given amount counts as tachtien and get a playful reason
  • Prompts and a Markdown resource expose the full entry
When to use it
Useful when you want a quick, self-contained novelty server for Dutch language play: explaining the word tachtien, generating example sentences, or rewriting Dutch or English texts so vague large amounts read as tachtien. It is a single-word joke site, not a general translation or dictionary service.
Requirements
Nothing to install: it is a remote Streamable HTTP endpoint with no authentication. Add the endpoint URL to an MCP client such as Claude, Cursor or ChatGPT; whether custom MCP servers can be added in ChatGPT depends on the plan and workspace settings. Network access is required.
Before you install
Text passed to the rewrite tool is sent to the remote server, so avoid pasting confidential content. The server is stateless and needs no credentials, but it is a third-party hosted service whose availability and content are outside your control. Answers are in Dutch.

Installation

In SourceWeft

  1. Open Tachtien 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/nl.tachtien%2Ftachtien/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

Examples

Ask Claude, or any MCP client, things like these. The answers are in Dutch, like the content.

  • "What does the Dutch word tachtien mean, how do you pronounce it, and where does it come from?" uses define: ontelbaar veel, IPA tɑxtin, a slip of the tongue from 2014, with sources.
  • "Rewrite this message with tachtien: 'Gisteren heel veel kopstootjes gedronken met ongeveer honderd man, en vandaag 3 aspirines.'" uses tachtienify: "Gisteren tachtien kopstootjes gedronken met tachtien man, en vandaag 3 aspirines." The exact 3 stays, because it was counted.
  • "I have more than 50 unread emails. Does that count as tachtien? And what about exactly 80?" uses is_tachtien: more than 50 is tachtien, because nobody counted; 80 is not, that is tachtig.
  • "Where has tachtien been mentioned in the press?" uses mentions with source: "press": four articles with links.

Tools

ToolInputReturns

examplesrandom?: booleanexample dialogues, or one at random
mentionssource?: "twitter" | "press" | "cityguys"external mentions with title, source and URL

Estimates ("ongeveer honderd", "zo'n 60", "~200", "100+") and lower bounds ("meer dan 50", "ruim honderd") are tachtien from 50 up, because nobody counted them. Exact numbers, smaller estimates and years ("rond 2014") are not.

Prompts

herschrijftekst: stringruns tachtienify on the server, then asks the model to fix the grammar
zinonderwerp?: stringasks for a new example sentence in the style of the site

Resource tachtien://entry is the whole entry as Markdown. Content is Dutch, as on the site; tool descriptions are English.

The first deploy creates the mcp.tachtien.nl DNS record and certificate, provided the tachtien.nl zone is in the same Cloudflare account.

Tools

define

Zoek tachtien op / Look up tachtien

Define the Dutch word 'tachtien' (a cardinal number meaning 'ontelbaar veel', uncountably many): syllables, part of speech, IPA pronunciation, definition and origin, as on tachtien.nl. Content is in Dutch.

Takes no parameters.

examples

Voorbeeldzinnen / Example sentences

Example sentences that use 'tachtien', in Dutch. Each example is a short dialogue of one or more lines.

Parametersrandom

mentions

Vermeldingen / Mentions

External mentions of 'tachtien' (tweets, press and Cityguys articles) with title, source and URL. The url is null for a mention without a link.

Parameterssource

tachtienify

Vervang vage aantallen / Replace vague amounts

Rewrite a text so that vague large amounts in Dutch or English ('heel veel', 'honderden', 'a lot of', 'countless', ...) and large estimates ('ongeveer honderd', '~200', '100+') become 'tachtien'. Exact numbers, small estimates and years are left alone. Returns the new text, the number of replacements and each replaced phrase with its index in the input.

Parameterstextrequired

is_tachtien

Is het tachtien? / Is it tachtien?

Judge whether an amount counts as 'tachtien' (uncountably many) and give a tongue-in-cheek reason in Dutch. Exact numbers never do (18 is achttien, 80 is tachtig, also inside a phrase like '18 biertjes'). Vague amounts like 'heel veel' or 'geen idee' do, and so do estimates of 50 or more, lower bounds included ('ongeveer honderd', 'meer dan 50', '100+'), because nobody counted; negation ('niet heel veel') makes either false.
