Check the health status of the RuVector connection and database.
AI agents call ruvector_health to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a diagnostic read operation that queries the health/status of a database connection. It has no side effects, does not modify data, execute code, or perform destructive operations. The blast radius of misuse is minimal—an agent could only receive false information about system health, not cause actual damage.
From the tool's definition Tool name 'ruvector_health' and description 'Check the health status of the RuVector connection and database' indicate a query/monitoring operation that retrieves status information without modifying or executing external operations.
Attacks that exploit this kind of access
Check the health status of the RuVector connection and database. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow MCP server in PolicyLayer and add a rule for ruvector_health: 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 Claude Flow. Nothing to install.
ruvector_health 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 ruvector_health 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 ruvector_health. 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.
ruvector_health is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
