2 of these tools change something. Run those 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

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Calculates the expected total annual costs for a household scenario: basic and supplementary premiums, collective discount (collectiviteitskorting, supplementary only), expected deductible (eigen risico), statutory co-payments (eigen bijdragen) and care costs that are not reimbursed, per person and in total, with all assumptions (aannames) and warnings such as provisional premiums. Input is a Scenario: insurance year, 1 to 8 persons with year of birth, chosen policy ids, voluntary deductible and, only if the user volunteers it, planned care per taxonomy category with counts (verwachtGebruik, optional). Do not ask about health; never put diagnoses, medicines or free text in the scenario; get_intake_schema lists the questions and allowed categories. Children under 18 pay no basic premium and no deductible. Provides information, not advice: the user makes the decision and signs up with the insurer themselves.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Checks per basic policy whether a care provider (zorgaanbieder, by AGB code) has a contract with the insurer (gecontracteerd) for a care type (zorgsoort), and which percentage of the costs is reimbursed without a contract. Each result states its origin (herkomst: insurer publication, the insurer's provider search (zorgzoeker), or cache) and the date it was retrieved. If herkomst is null the dataset has no contract information for that policy (status onbekend); calling again does not change that. Contracts can change during the year, so suggest the user confirms with the insurer. Provides information, not advice: the user makes the decision and signs up with the insurer themselves.

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.

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 zorgverzekering. Review it before you use it.
