AI agents call check_index_status to retrieve information from Omni Rag without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries the current state of an index to determine how fresh/current it is. It has no side effects, cannot modify data, and poses minimal risk. The low severity reflects that even misuse would only expose information about index metadata rather than sensitive file contents.
From the tool's definition Tool description states it 'Check[s] index freshness' - a query operation that retrieves status information. The tool is explicitly marked [Deprecated] and performs no modifications, deletions, or external operations.
Attacks that exploit this kind of access
[Deprecated: use 'check_status'] Check index freshness. It is categorised as a Read tool in the Omni Rag MCP Server, which means it retrieves data without modifying state.
Register the Omni Rag MCP server in PolicyLayer and add a rule for check_index_status: 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 Omni Rag. Nothing to install.
check_index_status 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 check_index_status 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 check_index_status. 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.
check_index_status is provided by the Omni Rag MCP server (suyash2013/codebase-rag-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
