# update_contact Update contact properties. Only specified fields are changed. Agent View of the PolicyLayer registry record for `update_contact`. HTML page: https://policylayer.com/tools/io-github-heznpc-iconnect/update-contact ## Facts - Tool: `update_contact` - Server: Iconnect (`iconnect-mcp`) — https://policylayer.com/tools/io-github-heznpc-iconnect.md - Install: `npx -y iconnect-mcp` - Homepage: https://github.com/heznpc/iConnect - 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": "update_contact", "arguments": {} } } ``` ## Why update_contact is rated Medium This tool modifies contact data in the Apple ecosystem (likely Contacts app on macOS). Updates are reversible operations that change existing records without destroying data or executing arbitrary code. The risk is medium because unauthorized contact modification could enable social engineering, fraud, or privacy violations, but the impact is limited to contact metadata and the changes can be undone. From the tool's own definition: "Tool name 'update_contact' and description 'Update contact properties' indicate modification of existing contact data. The phrase 'Only specified fields are changed' confirms reversible, targeted modification rather than deletion or creation." ## Use case AI agents use update_contact to create or update resources in Iconnect, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Iconnect environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Iconnect: ```json { "version": "1", "default": "deny", "tools": { "update_contact": { "limits": [ { "counter": "update_contact_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Iconnect (278) - `delete_contact` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-contact.md - `delete_event` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-event.md - `delete_note` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-note.md - `delete_photos` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-photos.md - `delete_playlist` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-playlist.md - `delete_reminder` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-reminder.md - `delete_reminder_list` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-reminder-list.md - `delete_shortcut` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/delete-shortcut.md - `memory_forget` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/memory-forget.md - `move_note` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/move-note.md - `remove_from_playlist` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/remove-from-playlist.md - `semantic_clear` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/semantic-clear.md - `spotlight_clear` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/spotlight-clear.md - `trash_file` — Destructive — https://policylayer.com/tools/io-github-heznpc-iconnect/trash-file.md - `activate_tab` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/activate-tab.md - `ai_agent` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-agent.md - `ai_chat` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-chat.md - `ai_plan_metrics` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/ai-plan-metrics.md - `connect_bluetooth` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/connect-bluetooth.md - `disconnect_bluetooth` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/disconnect-bluetooth.md - `edit_shortcut` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/edit-shortcut.md - `event_subscribe` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/event-subscribe.md - `generate_image` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/generate-image.md - `generate_text` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/generate-text.md - `gws_raw` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/gws-raw.md - `import_shortcut` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/import-shortcut.md - `keynote_start_slideshow` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/keynote-start-slideshow.md - `launch_app` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/launch-app.md - `local_llm_generate` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/local-llm-generate.md - `minimize_window` — Execute — https://policylayer.com/tools/io-github-heznpc-iconnect/minimize-window.md - …and 248 more: https://policylayer.com/tools/io-github-heznpc-iconnect.md ## For agents This record is a snapshot.
