Medium Risk

uml_class_diagram

Create a UML class diagram. Call this tool when the user asks to draw, create, or model a class diagram, domain model, or object structure. Returns full instructions — follow them exactly to produce a self-contained HTML file, then call uml_write_file to save it to disk.

Part of the Sad MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

sad-mcp Write

AI agents use uml_class_diagram to create or modify resources in Sad. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call uml_class_diagram repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Sad.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the uml_class_diagram tool do? +

Create a UML class diagram. Call this tool when the user asks to draw, create, or model a class diagram, domain model, or object structure. Returns full instructions — follow them exactly to produce a self-contained HTML file, then call uml_write_file to save it to disk.. It is categorised as a Write tool in the Sad MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on uml_class_diagram? +

Add a rule in your Intercept YAML policy under the tools section for uml_class_diagram. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Sad MCP server.

What risk level is uml_class_diagram? +

uml_class_diagram is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit uml_class_diagram? +

Yes. Add a rate_limit block to the uml_class_diagram rule in your Intercept 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.

How do I block uml_class_diagram completely? +

Set action: deny in the Intercept policy for uml_class_diagram. 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.

What MCP server provides uml_class_diagram? +

uml_class_diagram is provided by the Sad MCP server (sad-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
