# change_deck A write tool on the Anki MCP server. Agent View of the PolicyLayer registry record for `change_deck`. HTML page: https://policylayer.com/tools/io-github-arielbk-anki-mcp/change-deck ## Facts - Tool: `change_deck` - Server: Anki (`@arielbk/anki-mcp`) — https://policylayer.com/tools/io-github-arielbk-anki-mcp.md - Install: `npx -y @arielbk/anki-mcp` - Homepage: https://github.com/arielbk/anki-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "change_deck", "arguments": {} } } ``` ## Why change_deck is rated Medium Moving cards between decks is a Write operation—it modifies data state but is reversible (cards can be moved back). It is not Destructive (no deletion or permanent loss), not Execute (no arbitrary command execution), and not Financial. The lack of a description lowers confidence slightly, but the naming and context of related tools support Write classification. From the tool's own definition: "Tool name 'change_deck' indicates modification of flashcard organization in Anki. While the description is empty, the sibling tools (add_note, add_tags_to_notes, answer_cards) show this server performs reversible data modifications to an Anki collection." ## Use case AI agents use change_deck to create or update resources in Anki, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Anki environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Anki: ```json { "version": "1", "default": "deny", "tools": { "change_deck": { "limits": [ { "counter": "change_deck_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Anki (97) - `clear_unused_tags` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/clear-unused-tags.md - `delete_decks` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/delete-decks.md - `delete_media_file` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/delete-media-file.md - `delete_notes` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/delete-notes.md - `gui_exit_anki` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-exit-anki.md - `manage_decks` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/manage-decks.md - `model_field_remove` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/model-field-remove.md - `model_template_remove` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/model-template-remove.md - `remove_deck_config` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/remove-deck-config.md - `remove_empty_notes` — Destructive — https://policylayer.com/tools/io-github-arielbk-anki-mcp/remove-empty-notes.md - `anki_operations` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/anki-operations.md - `gui_answer_card` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-answer-card.md - `gui_deck_browser` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-deck-browser.md - `gui_deck_review` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-deck-review.md - `gui_select_card` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-select-card.md - `gui_select_note` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-select-note.md - `gui_show_answer` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-show-answer.md - `gui_show_question` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-show-question.md - `gui_start_card_timer` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-start-card-timer.md - `relearn_cards` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/relearn-cards.md - `reload_collection` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/reload-collection.md - `study_session` — Execute — https://policylayer.com/tools/io-github-arielbk-anki-mcp/study-session.md - `api_reflect` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/api-reflect.md - `card_reviews` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/card-reviews.md - `export_package` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/export-package.md - `gui_browse` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-browse.md - `gui_undo` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/gui-undo.md - `multi` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/multi.md - `request_permission` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/request-permission.md - `sync` — Other — https://policylayer.com/tools/io-github-arielbk-anki-mcp/sync.md - …and 67 more: https://policylayer.com/tools/io-github-arielbk-anki-mcp.md ## For agents This record is a snapshot.
