Get PlantUML and Java version information.
AI agents call get_plantuml_version to retrieve information from PlantUML MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and returns version information about PlantUML and Java installations. It is a read-only operation with no side effects, no data modification, no code execution, and no destructive capability. The blast radius of misuse is minimal—an attacker could at most gather system information for reconnaissance, which is low severity.
From the tool's definition Tool name 'get_plantuml_version' and description 'Get PlantUML and Java version information' indicate a query operation that retrieves version data without modifying any state or executing user-controlled code.

get_plantuml_version 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_plantuml_version 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_plantuml_version. 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_plantuml_version is provided by the PlantUML MCP Server MCP server (junqing258/plantuml-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
