Dyscalculia.io MCP

An official, free, read-only MCP server that allows AI assistants to query sourced dyscalculia prevalence statistics, underlying study details, and the methodology of the free screening test. It supports both hosted remote access and local execution via npx.

get_prevalence — Dyscalculia prevalence figures
Advertised by the server during the last successful anonymous check.
Advertised read-only

Published dyscalculia prevalence figures with sample size, publication year, age, the reference key (see get_reference) and a calc flag (true when the site calculated the figure itself). Filter by study id, by age (entries whose stated age range includes it; entries with no stated age are never matched) or by a percent range (entries whose figure or range overlaps it). With no filter, returns all 10 entries. These are published research estimates, not a diagnosis of any person. There is no worldwide pooled meta-analysis of dyscalculia prevalence: the 'worldwide' entry is a range across population studies. Studies use different criteria and ages, so figures are not directly comparable.

list_studies — List the studies and sources behind the statistics
Advertised by the server during the last successful anonymous check.
Advertised read-only

Lists every source the statistics page cites (peer-reviewed studies with DOI or PMID, plus official statistics and guidelines), with the topics each supports and, for population studies, the prevalence entries built from them. Filter by topic: prevalence, persistence, math-anxiety, interventions, by-country, sex-ratio, comorbidity, key-figures, family, official-counts, method. Use get_reference for one full citation.

get_reference — Get one full reference
Advertised by the server during the last successful anonymous check.
Advertised read-only

Full citation for one reference key (for example shalev2000, grosstsur1996), with its DOI and PMID when the site has them, the link the site uses, and the topics that cite it. The site holds 93 references; keys are returned by get_prevalence and list_studies.

explain_screening_test — Explain the free number-skills screening test
Advertised by the server during the last successful anonymous check.
Advertised read-only

Describes the five screening games on dyscalculia.io: what each measures, how many items it has, what an item is and how items and games are scored in general terms, and the limits. Optionally returns the item sets (dot counts, number pairs, number-line targets, digit-sequence lengths). It describes the test only: it does not score anyone, take answers or return a result. The test is a screening of basic number skills, not a diagnosis.

list_chart_data — Charts and tables on the statistics page
Advertised by the server during the last successful anonymous check.
Advertised read-only

Lists the chart and table datasets on the statistics page (id, title, topic, section, row count) with their download addresses: the CSV and JSON of the whole page, one SVG per chart, the screening-test JSON and the changelog JSON. Pass an id (for example chart-1, table-2) to get that dataset's rows with their values, notes and reference keys.

Advertised by the server during the last successful anonymous check.
Advertised read-only

License (the compilation is CC BY 4.0; each figure belongs to its cited source), the citation text, an HTML credit link and the download addresses. To cite a single number, cite its study: use get_reference.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http dyscalculia-io-mcp https://mcp.dyscalculia.io/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add dyscalculia-io-mcp --url https://mcp.dyscalculia.io/mcp

Cursor configuration
{
  "mcpServers": {
    "dyscalculia-io-mcp": {
      "url": "https://mcp.dyscalculia.io/mcp"
    }
  }
