Dutch Fluency Discovery MCP

Anonymous, read-only discovery over the public Dutch Fluency library: podcast transcripts, articles and learning products already published on www.dutchfluency.com.

Two services, different jobs

Service	Endpoint	Use it for	Do not use it for
Dutch Fluency Learning MCP	`https://mcp.dutchfluency.com/mcp`	Grammar checking, KNM and NT2 practice, adaptive CEFR assessment, certificates, a learner's own progress	General content search
Dutch Fluency Discovery MCP	`https://discover.dutchfluency.com/mcp`	Public search, retrieval, citations, learning paths, product discovery	Accounts, purchases, learner progress, grading

Calling the wrong one is the common mistake. To find and cite Dutch content, use Discovery. To practise, be graded, or check a certificate, use Learning.

Connecting

Both speak MCP Streamable HTTP. POST JSON-RPC to the endpoint with:

Content-Type: application/json
Accept: application/json, text/event-stream

Both media types are required by the transport; sending only one is refused with 406. The advertised endpoint takes POST directly and never redirects.

Verified working: Claude Code, which completed initialize and a tool call against this endpoint. Other Streamable HTTP clients are expected to work but are not claimed here, because they have not been tested.

Tools

dfl_search_library: full-text search across public transcripts, articles and products
dfl_get_resource: retrieve one resource by stable id or canonical URL
dfl_browse_topics: aggregate topics with representative citations
dfl_recommend_learning_path: build an ordered path for a stated goal
dfl_find_learning_product: match a goal to a learning product

REST and descriptions

Privacy and availability

Anonymous. No account is required and none can be used.
Read-only. There is no write path of any kind.
Rate limited per caller; exceeding it returns 429 with Retry-After.
Only content already published on www.dutchfluency.com is reachable. No learner, account, billing or session data exists in this service.
A scheduled audit proves the published projection matches the website exactly, with nothing missing and nothing extra.
Transcripts are indexed by metadata; full transcript text lives on the canonical page.
Readiness: /readyz

Citing

Every resource carries a canonical URL on www.dutchfluency.com. Cite that URL rather than an API endpoint. CEFR levels are Dutch Fluency's own assessment against CEFR descriptors, not a state examination result.
