Score how surprising/novel new content is compared to existing memories. High scores indicate contradictions with stored knowledge.
AI agents call memory_surprise to retrieve information from Kova Mind MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a scoring and comparison function against existing memory data. It is purely analytical—it reads stored knowledge, performs a scoring calculation, and returns results. There is no modification of data (Write), no execution of commands (Execute), no irreversible deletion (Destructive), no financial implications (Financial), and no external side effects.

Attacks that exploit this kind of access
Score how surprising/novel new content is compared to existing memories. High scores indicate contradictions with stored knowledge. It is categorised as a Read tool in the Kova Mind MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kova Mind MCP Server MCP server in PolicyLayer and add a rule for memory_surprise: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kova Mind MCP Server. Nothing to install.
memory_surprise 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 memory_surprise 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 memory_surprise. 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.
memory_surprise is provided by the Kova Mind MCP Server MCP server (kovamind/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
