DWDS MCP — German Digital Dictionary.

What can you do with Dwds?

  • snippet(query) — dictionary entry summary for a German word (part of speech, base lemma, link to full entry). Exact lemmas only.
  • dwds_frequency(query) — how common a German word is: absolute hit count + per-million frequency in the DWDS reference corpus.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Environment variables

  • PIPEWORX_API_KEY secret Optional Pipeworx API key. Without it calls are anonymous and capped daily; a free key raises the cap.

@pipeworx/dwds

DWDS MCP — German Digital Dictionary (Digitales Wörterbuch der deutschen Sprache). Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1855+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

  • snippet(query) — dictionary entry summary for a German word (part of speech, base lemma, link to full entry). Exact lemmas only.
  • dwds_frequency(query) — how common a German word is: absolute hit count + per-million frequency in the DWDS reference corpus.

Auth

None — keyless.

Removed tools

  • lemma — removed 2026-08-07. Called /api/lemma/, which 404s for every input; the endpoint was never documented and never worked. No keyless lemmatizer replacement exists (/wb/snippet, dwdsmor, wb/lemma all fail on inflected forms).
  • corpus_concordance / kwic — removed 2026-08-31 (fleet #729). DWDS retired its public corpus-concordance / KWIC API; corpus search moved to the access-restricted "dstar" platform (ddc.dwds.de), which no longer serves JSON. No keyless replacement exists. For raw corpus example sentences, search manually at https://www.dwds.de.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "dwds": {
      "url": "https://gateway.pipeworx.io/dwds/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/dwds/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1855+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/snippet \
  -H 'Content-Type: application/json' \
  -d '{"query":"Haus"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/snippet. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "dwds": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-dwds"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-dwds

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Dwds data" })

The gateway picks the right tool and fills the arguments automatically.

Frequently asked questions

What is Dwds?

DWDS MCP — German Digital Dictionary.

How do I install Dwds?

It runs as a remote server. In Claude Code: claude mcp add --transport http dwds 'https://gateway.pipeworx.io/dwds/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Dwds need an API key?

Yes. It expects PIPEWORX_API_KEY, which you set in its configuration.

Is Dwds open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains Dwds?

It is published by pipeworx-io. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
