# model_field_add A write tool on the Anki MCP server. Agent View of the PolicyLayer registry record for `model_field_add`. HTML page: https://policylayer.com/tools/io-github-arielbk-anki-mcp/model-field-add ## Facts - Tool: `model_field_add` - 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": "model_field_add", "arguments": {} } } ``` ## Why model_field_add is rated Medium This tool creates or modifies Anki model schemas by adding fields, which is a reversible Write operation. It affects data structure rather than executing arbitrary code or causing irreversible deletion. Medium severity reflects that schema changes could impact multiple cards but are generally reversible through model editing. From the tool's own definition: "Tool name 'model_field_add' indicates addition of a field to an Anki card model; the server context shows tools that create and modify Anki flashcard data (add_note, add_notes, add_tags_to_notes). The description is empty, limiting certainty." ## Use case AI agents use model_field_add 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": { "model_field_add": { "limits": [ { "counter": "model_field_add_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.
