Changes things 2Creates or changes something that can be changed back.Claude Code: ask

get_code_definitionRetrieve one exact code or codelist container, including its node_kind, hierarchy position and explanatory notes.1 finding
Why it is in this group
- The name "get_code_definition" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
  The server marks "get_code_definition" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

- openWorldHint: false
map_codesApply official stored correspondences and expose splits, merges, changed meanings and unmapped codes.1 finding
Why it is in this group

Description, as the server wrote it
Apply official stored correspondences and expose splits, merges, changed meanings and unmapped codes. Never assume one-to-one equivalence.
Annotations the server declares

Only reads 8Looks things up and changes nothing.Claude Code: allow

browse_hierarchyBrowse top-level nodes or immediate children.No findings
Why it is in this group
- The name "browse_hierarchy" says "browse": a word for reading.
Description, as the server wrote it
Browse top-level nodes or immediate children. Curated families return node_kind=codelist containers at root; pass that code as parent_code to browse its options.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
export_choice_listReturn a structured choice list at a selected hierarchy level.No findings
Why it is in this group
- The name "export_choice_list" says "list": a word for reading.
Description, as the server wrote it
Return a structured choice list at a selected hierarchy level. MICS exports require one codelist_id and never merge unrelated answer lists.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_classificationGet authoritative metadata and coverage for one classification_id returned by list_classifications.No findings
Why it is in this group
- The name "get_classification" says "get": a word for reading.
Description, as the server wrote it
Get authoritative metadata and coverage for one classification_id returned by list_classifications.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_classificationsList classification families, versions, custodians, coverage and licensing notes.No findings
Why it is in this group
- The name "list_classifications" says "list": a word for reading.
Description, as the server wrote it
List classification families, versions, custodians, coverage and licensing notes. Start here when the correct standard is unknown.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_codelistsList independent option lists within a classification before searching or exporting one list.No findings
Why it is in this group
- The name "list_codelists" says "list": a word for reading.
Description, as the server wrote it
List independent option lists within a classification before searching or exporting one list.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
recommend_classificationsReturn a deterministic ranked shortlist of all relevant classification concepts and codelists.No findings
Why it is in this group
- The description's first verb is "return": a word for reading.
Description, as the server wrote it
Return a deterministic ranked shortlist of all relevant classification concepts and codelists. Ranking supports user choice; it is not an automatic selection. Include answer options and context.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
search_codesFull-text search labels and notes.No findings
Why it is in this group
- The name "search_codes" says "search": a word for reading.
Description, as the server wrote it
Full-text search labels and notes. Results restrict to one option list only when codelist_id is explicitly supplied.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
validate_codesValidate exact codes against one named classification version.No findings
Why it is in this group
- The name "validate_codes" says "validate": a word for reading.
Description, as the server wrote it
Validate exact codes against one named classification version.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

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.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as international-classifications. Review it before you use it.

Anlyon alternative

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.
