# record_event Record an n-ary event: the action becomes a first-class event hub entity with role-typed relations (actor_of/targeted/occurred_in/participant_in). Missing endpoints auto-create as concept stubs. Optional flowKey groups events into a named flow. Agent View of the PolicyLayer registry record for `record_event`. HTML page: https://policylayer.com/tools/danielsimonjr-memory-mcp/record-event ## Facts - Tool: `record_event` - Server: Enhanced Knowledge Graph Memory Server (`danielsimonjr/memory-mcp`) — https://policylayer.com/tools/danielsimonjr-memory-mcp.md - Homepage: https://github.com/danielsimonjr/memory-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": "record_event", "arguments": {} } } ``` ## Why record_event is rated Medium This tool creates and stores event records in the knowledge graph with automatic entity creation. It performs data creation and modification but does not delete data, execute arbitrary commands, move funds, or trigger destructive operations. The 'auto-create' behavior and entity relation establishment are characteristic of Write operations. From the tool's own definition: "Tool description states the action 'becomes a first-class event hub entity' with relations created, indicating data creation. 'Missing endpoints auto-create as concept stubs' confirms that the tool writes new entities to the knowledge graph when invoked." ## Use case AI agents use record_event to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Enhanced Knowledge Graph Memory Server: ```json { "version": "1", "default": "deny", "tools": { "record_event": { "limits": [ { "counter": "record_event_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Enhanced Knowledge Graph Memory Server (240) - `adaptive_reduce_memories` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/adaptive-reduce-memories.md - `add_exclusion_rule` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/add-exclusion-rule.md - `cache_clear` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/cache-clear.md - `check_graph` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/check-graph.md - `clear_expired_memories` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/clear-expired-memories.md - `clear_heuristics` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/clear-heuristics.md - `clear_project_context` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/clear-project-context.md - `consolidate_relations` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/consolidate-relations.md - `delete_entities` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/delete-entities.md - `delete_observations` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/delete-observations.md - `delete_relations` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/delete-relations.md - `delete_saved_search` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/delete-saved-search.md - `deregister_ref` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/deregister-ref.md - `forget_memory` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/forget-memory.md - `forget_weak_memories` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/forget-weak-memories.md - `rbac_revoke_role` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/rbac-revoke-role.md - `remove_exclusion_rule` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-exclusion-rule.md - `remove_heuristic` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-heuristic.md - `remove_project_command` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-project-command.md - `remove_project_convention` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-project-convention.md - `remove_project_fact` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-project-fact.md - `remove_project_glossary_term` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-project-glossary-term.md - `remove_tag_alias` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-tag-alias.md - `remove_tool_affordance` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/remove-tool-affordance.md - `consolidate_session` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/consolidate-session.md - `dream_run_now` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/dream-run-now.md - `dream_start` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/dream-start.md - `dream_stop` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/dream-stop.md - `end_session` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/end-session.md - `run_consolidation_now` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/run-consolidation-now.md - …and 210 more: https://policylayer.com/tools/danielsimonjr-memory-mcp.md ## For agents This record is a snapshot.
