# memory_create_relations Create and store multiple new relationships between entities in the user Agent View of the PolicyLayer registry record for `memory_create_relations`. HTML page: https://policylayer.com/tools/3xcaffeine-mcp-server/memory-create-relations ## Facts - Tool: `memory_create_relations` - Server: VaultAssist (`3xcaffeine/mcp-server`) — https://policylayer.com/tools/3xcaffeine-mcp-server.md - Homepage: https://github.com/3xcaffeine/mcp-server - 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": "memory_create_relations", "arguments": {} } } ``` ## Why memory_create_relations is rated Medium The tool creates and stores new relationships, which is a reversible write operation. It doesn't retrieve data (Read), execute external commands (Execute), irreversibly delete data (Destructive), or involve financial transactions (Financial). The medium severity reflects that bulk relationship creation could impact user data organization and privacy, but relationships can typically be modified or deleted afterward. From the tool's own definition: "Tool name includes 'create' and description states 'Create and store multiple new relationships between entities'; this is a data creation operation that modifies user state." ## Use case AI agents use memory_create_relations to create or update resources in VaultAssist, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your VaultAssist environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches VaultAssist: ```json { "version": "1", "default": "deny", "tools": { "memory_create_relations": { "limits": [ { "counter": "memory_create_relations_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on VaultAssist (78) - `batch_delete_gmail_emails` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/batch-delete-gmail-emails.md - `clear_completed_tasks` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/clear-completed-tasks.md - `delete_event` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/delete-event.md - `delete_gmail_email` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/delete-gmail-email.md - `delete_gmail_label` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/delete-gmail-label.md - `delete_task` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/delete-task.md - `delete_task_list` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/delete-task-list.md - `memory_delete_entities` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/memory-delete-entities.md - `memory_delete_observations` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/memory-delete-observations.md - `memory_delete_relations` — Destructive — https://policylayer.com/tools/3xcaffeine-mcp-server/memory-delete-relations.md - `roll_dice` — Other — https://policylayer.com/tools/3xcaffeine-mcp-server/roll-dice.md - `sequentialthinking` — Other — https://policylayer.com/tools/3xcaffeine-mcp-server/sequentialthinking.md - `about` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/about.md - `debug_table_structure` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/debug-table-structure.md - `echo` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/echo.md - `get_doc_content` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-doc-content.md - `get_drive_file_content` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-drive-file-content.md - `get_event` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-event.md - `get_events` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-events.md - `get_form` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-form.md - `get_form_response` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-form-response.md - `get_page` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-page.md - `get_page_thumbnail` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-page-thumbnail.md - `get_presentation` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-presentation.md - `get_spreadsheet_info` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-spreadsheet-info.md - `get_task` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-task.md - `get_task_list` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-task-list.md - `get_user_info` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/get-user-info.md - `inspect_doc_structure` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/inspect-doc-structure.md - `list_calendars` — Read — https://policylayer.com/tools/3xcaffeine-mcp-server/list-calendars.md - …and 48 more: https://policylayer.com/tools/3xcaffeine-mcp-server.md ## For agents This record is a snapshot.
