Find duplicate or very similar notes in the database
AI agents call analysis-find-duplicates to retrieve information from MCP Index Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs analysis on existing notes by identifying duplicates through comparison—a read-only operation that queries the database and returns results. There are no side effects, data modifications, deletions, or external executions involved. The low severity reflects minimal blast radius: misuse would only surface unwanted duplicate detection results without affecting data integrity or system state.
From the tool's definition Tool name 'analysis-find-duplicates' and description 'Find duplicate or very similar notes in the database' indicate a search/query operation that retrieves and compares existing data without modifying, deleting, or executing external operations.

analysis-find-duplicates is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the analysis-find-duplicates rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for analysis-find-duplicates. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
