design_architecture · Tok MCP: Risk & Policy

WHAT IT DOES

What design_architecture does on Tok

AI agents use design_architecture to create or update resources in Tok — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tok environment.

WHY IT NEEDS A POLICY

Why design_architecture needs a policy

The tool creates new files (ARCHITECTURE.md and .ai-context.yaml) based on interactive consultation inputs. This is a Write operation as it produces structured artifacts. It does not execute code, delete data, or move money. Severity is medium because the generated architecture files guide AI coding tools in building infrastructure, meaning poor recommendations could propagate into actual system builds.

From the tool's definition 'ARCHITECTURE.md와 .ai-context.yaml 문서를 생성합니다' — generates/creates structured documentation files; '대화형 질문을 통해 서비스에 맞는 아키텍처를 설계합니다' — designs architecture through interactive consultation

Verdict

design_architecture Rate-limited

design_architecture stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Tok, so you can run agents against it safely.

FAQ

Questions about design_architecture

What does the design_architecture tool do? +

대화형 질문을 통해 서비스에 맞는 아키텍처를 설계합니다. 플랫폼, 규모, 예산 등을 분석하여 최적의 아키텍처를 추천하고 ARCHITECTURE.md와 .ai-context.yaml 문서를 생성합니다. It is categorised as a Write tool in the Tok MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on design_architecture? +

Register the Tok MCP server in PolicyLayer and add a rule for design_architecture: 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 Tok. Nothing to install.

What risk level is design_architecture? +

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

Can I rate-limit design_architecture? +

Yes. Add a rate_limit block to the design_architecture 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.

How do I block design_architecture completely? +

Set action: deny in the PolicyLayer policy for design_architecture. 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 design_architecture? +

design_architecture is provided by the Tok MCP server (seongminjaden/tok_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
