AI agents call get_network_stats to retrieve information from Joy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns aggregated network statistics without any side effects, data modification, execution of code, or financial operations. It is a straightforward read operation that gathers monitoring/observability data about the Joy network's status.
From the tool's definition get_network_stats - retrieves network statistics (total agents, messages, and health) with no modification capability
Attacks that exploit this kind of access
Get Joy network statistics - total agents, messages, and health. It is categorised as a Read tool in the Joy MCP Server, which means it retrieves data without modifying state.
Register the Joy MCP server in PolicyLayer and add a rule for get_network_stats: 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 Joy. Nothing to install.
get_network_stats 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 get_network_stats 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 get_network_stats. 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.
get_network_stats is provided by the Joy MCP server (@joy-trust/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
