Changes things 3Creates or changes something that can be changed back.Claude Code: ask

worlds_advise_hard_problemChoose the maximum-depth model-and-effort pairing for one difficult problem within the caller's actual CLI set.No findings
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
Choose the maximum-depth model-and-effort pairing for one difficult problem within the caller's actual CLI set. For a single CLI it selects that provider's strongest catalog role; with multiple CLIs it returns provider candidates but does not invent a universal cross-provider winner. It uses single-task depth, never ultra or ultracode orchestration, defaults to read-only, and does not launch a CLI or grant permissions.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
worlds_get_cli_commandReturn one current command path with all captured flags, arguments, value shapes, availability, risk, release metadata, and official source links.1 finding
Why it is in this group
- The name "worlds_get_cli_command" says "get": a word for reading.
- The input takes a statement or command to run (input.command), 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 "worlds_get_cli_command" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Description, as the server wrote it
Return one current command path with all captured flags, arguments, value shapes, availability, risk, release metadata, and official source links. Accepts a stable id or full command path.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true

worlds_plan_cli_workCreate a read-only, dependency-aware work plan across Claude Code, Codex, and Grok Build.1 finding
Why it is in this group
- The description's first verb is "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  Matched text
  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "create": a word for a change.
  What this check looks for
Description, as the server wrote it
Create a read-only, dependency-aware work plan across Claude Code, Codex, and Grok Build. It selects a concrete dated-catalog model and supported native effort for each workstream, while keeping CLI fit, orchestration, permissions, handoff context, and verification separate. Routing is continuity-first and does not claim benchmark superiority, launch another CLI, or enable permission bypass.

Why it is in this group
- The name "worlds_search_knowledge" says "search": a word for reading.
Description, as the server wrote it
Search 162 multilingual, source-checked operating manuals for Claude Code, Codex, and Grok Build: 18 CLI usage and feature modules per product in English, Traditional Chinese, and Japanese. Website articles, news, newsletters, opinion, and release archives are not in this corpus. Returns bounded excerpts, commands when present, canonical links, official sources, and review dates.

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.

3 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.
