Get system diagnostic information
AI agents call get_diagnostics to retrieve information from HC3 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic data from the HC3 system without creating, modifying, deleting, or executing any actions. Diagnostic information is typically system metrics, logs, and status information used for monitoring and troubleshooting. No side effects or state changes occur.
From the tool's definition Tool name 'get_diagnostics' and description 'Get system diagnostic information' indicate a retrieval operation with no modification or execution of commands. The verb 'Get' and the purely informational nature of diagnostics data confirm read-only behavior.
Attacks that exploit this kind of access
Get system diagnostic information. It is categorised as a Read tool in the HC3 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HC3 MCP Server MCP server in PolicyLayer and add a rule for get_diagnostics: 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 HC3 MCP Server. Nothing to install.
get_diagnostics 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_diagnostics 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_diagnostics. 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_diagnostics is provided by the HC3 MCP Server MCP server (jangabrielsson/hc3_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
