What oracle_search does on Oracle MCP

AI agents call oracle_search to retrieve information from Oracle MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why oracle_search needs a policy

This tool performs information retrieval operations only. It searches and queries existing knowledge without creating, modifying, deleting, or executing operations. The hybrid search mechanism (full-text search + vector similarity) is inherently a read operation. Misuse would be limited to retrieving unintended information, representing low severity exposure.

From the tool's definition Tool description explicitly states it 'Search[es] Oracle knowledge base' and 'Finds relevant principles, patterns, learnings, or retrospectives.' Uses hybrid search (FTS5 keywords + ChromaDB vectors) which are read-only query mechanisms.
