AI agents call ping to retrieve information from Neosql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
A health-check or ping tool performs no side effects: it does not create, modify, delete, or execute operations. It simply returns status information about the service, making it a Read category tool with low severity and minimal risk if misused by an agent.
From the tool's definition Tool name is 'ping' described as 'Health-check tool. Returns' — a diagnostic operation that queries system status without modifying state. Consistent with standard health-check semantics (e.g., HTTP HEAD/GET requests) that retrieve information only.

Health-check tool. Returns. It is categorised as a Read tool in the Neosql MCP Server, which means it retrieves data without modifying state.
Register the Neosql MCP server in PolicyLayer and add a rule for ping: 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 Neosql. Nothing to install.
ping 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 ping 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 ping. 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.
ping is provided by the Neosql MCP server (unvus/neosql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
