# search_by_date_range Search entities within a date range, with optional filtering by entity type and tags. At least one of startDate or endDate should be provided. Agent View of the PolicyLayer registry record for `search_by_date_range`. HTML page: https://policylayer.com/tools/danielsimonjr-memory-mcp/search-by-date-range ## Facts - Tool: `search_by_date_range` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "search_by_date_range", "arguments": {} } } ``` ## Why search_by_date_range is rated Low This tool retrieves or queries data from the knowledge graph based on date range and optional filters (entity type, tags). It has no side effects, does not modify state, and matches the Read category definition of 'retrieves or queries data; no side effects.' The severity is low because even if an AI agent misuses this for overly broad searches, the blast radius is limited to information disclosure with no… From the tool's own definition: "Tool description specifies 'Search entities within a date range' with optional filtering parameters. The operation is a query/retrieval function with no modification, creation, deletion, or execution capabilities." ## Use case AI agents call search_by_date_range to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. 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": { "search_by_date_range": {} } } ``` ## Other tools on Enhanced Knowledge Graph Memory Server (224) - `adaptive_reduce_memories` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/adaptive-reduce-memories.md - `cache_clear` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/cache-clear.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 - `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 - `invalidate_entity` — Destructive — https://policylayer.com/tools/danielsimonjr-memory-mcp/invalidate-entity.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 - `parse_adr_markdown` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/parse-adr-markdown.md - `run_consolidation_now` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/run-consolidation-now.md - `run_decay_cycle` — Execute — https://policylayer.com/tools/danielsimonjr-memory-mcp/run-decay-cycle.md - …and 194 more: https://policylayer.com/tools/danielsimonjr-memory-mcp.md ## For agents This record is a snapshot.
