Anlyon alternative

Run the operations that matter as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Why it is in this group

    • The name "explain_screening_test" says "explain": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "get_prevalence" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "get_reference" says "get": a word for reading.
    Description, as the server wrote it
    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.

    • The name "list_chart_data" says "list": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "list" and "table": it reads databases.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_studies" says "list": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

  "permissions": {
    "allow": [
      "mcp__dyscalculia__get_prevalence",

    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as dyscalculia. Review it before you use it.

Capability tags behind 2 rules
