# audit_history Get the full audit history for a specific entity in chronological order Agent View of the PolicyLayer registry record for `audit_history`. HTML page: https://policylayer.com/tools/danielsimonjr-memory-mcp/audit-history ## Facts - Tool: `audit_history` - 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": "audit_history", "arguments": {} } } ``` ## Why audit_history is rated Low This is a straightforward audit log query that returns historical records of changes to a specific entity. Reading audit logs is a read-only operation with no capacity to modify data, execute operations, or cause financial impact. The blast radius of misuse is minimal—unauthorized access to audit history could reveal sensitive information about what changes were made, but cannot itself alter or delete data. From the tool's own definition: "Tool retrieves audit history in 'chronological order' with no modification or deletion capability mentioned. The verb 'Get' explicitly indicates data retrieval without side effects." ## Use case AI agents call audit_history 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": { "audit_history": {} } } ``` ## 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.
