Sommaire
dyscalculia-mcp
MCP server for the sourced dyscalculia statistics on Dyscalculia.io: prevalence studies with sample size, year, age and reference, 93 references with DOI or PMID where the site has one, the chart and table datasets, and a plain description of the five number-skill screening games. Ask an assistant "what share of children have dyscalculia, and which study says so?" and it answers from sourced figures. Read-only.
Tools
| Tool | What it returns |
|---|---|
get_prevalence | Prevalence figures with sample size, publication year, age, reference key and a calc flag; filter by study, age or percent range |
list_studies | Every source the statistics page cites, with the topics it supports (prevalence, sex ratio, comorbidity, persistence, family, maths anxiety, interventions, ...) |
get_reference | One full citation by key (for example shalev2000) with DOI or PMID where the site has one, and the topics that cite it |
explain_screening_test | The five screening games: what each measures, item counts, how items and games are scored in general terms, optional item sets, and the limits |
list_chart_data | The 4 charts and 3 tables on the statistics page with their CSV, JSON and SVG addresses; pass an id to get the rows with notes and reference keys |
get_citation | License (CC BY 4.0 compilation, each figure belongs to its source), citation text, an HTML credit link and downloads |
Every tool is read-only (readOnlyHint). Invalid input returns isError with the valid options. No tool scores a person,
takes answers or returns a screening result: explain_screening_test describes the test, nothing more.

Local:
{ "mcpServers": { "dyscalculia": { "command": "npx", "args": ["-y", "dyscalculia-mcp"] } } }Claude Code: claude mcp add --scope user dyscalculia -- npx -y dyscalculia-mcp.
Self-host the HTTP transport: npm run build && PORT=3000 npm run start:http (POST /mcp, stateless, /health), or build the
Dockerfile (node:22-alpine, non-root, port 3000).
Honest limits
- There is no global prevalence figure. No worldwide pooled meta-analysis of dyscalculia prevalence was found; the "worldwide" entry is a range across population studies. Studies use different criteria and ages, so figures are not directly comparable, and one English sample gave 1 to 6 percent depending on the cut-off.
- The figures are published research estimates, not a diagnosis of any person. The server gives no advice about a learning difficulty and does not tell anyone whether they have dyscalculia.
- The screening test is a screening of basic number skills. It has no norm sample, no percentiles and no published accuracy study; it does not diagnose dyscalculia and does not rule it out.
- DOIs and PMIDs are exactly those the site prints. Where the site has none, none is given.
