# detect_contradictions Find conflicting observations within an entity using semantic similarity Agent View of the PolicyLayer registry record for `detect_contradictions`. HTML page: https://policylayer.com/tools/danielsimonjr-memory-mcp/detect-contradictions ## Facts - Tool: `detect_contradictions` - 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": "detect_contradictions", "arguments": {} } } ``` ## Why detect_contradictions is rated Low This tool retrieves and analyzes data to identify semantic contradictions but does not create, modify, delete, or execute external operations. It has no side effects on the knowledge graph beyond examining what already exists. The blast radius of misuse is minimal—at worst, an AI agent receives potentially incorrect contradiction analysis, but no data is altered or financial impact occurs. From the tool's own definition: "The tool 'detect_contradictions' analyzes existing observations within an entity to find conflicts using semantic similarity. The verb 'detect' and the phrase 'find conflicting observations' indicate a query/analysis operation with no modification of data." ## Use case AI agents call detect_contradictions 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": { "detect_contradictions": {} } } ``` ## 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.
