garasegae/aiskillstore Write Risk 3/5

AI agents use upload_skill to create or modify resources in AI Skill Store. 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 upload_skill 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 AI Skill Store.

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

  upload_skill:
    rules:
      - action: allow
        rate_limit:
          max: 30

What does the upload_skill tool do? +

스킬 파일을 AI Skill Store에 업로드합니다. API 키가 필요합니다. 소유자는 API 키를 통해 서버에서 자동으로 확인됩니다. Args: file_path: 업로드할 .skill 파일의 절대 경로 api_key: 개발자 API 키 Returns: 업로드 결과 메시지 . It is categorised as a Write tool in the AI Skill Store MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on upload_skill? +

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

What risk level is upload_skill? +

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

Can I rate-limit upload_skill? +

Yes. Add a rate_limit block to the upload_skill 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 upload_skill completely? +

Set action: deny in the Intercept policy for upload_skill. 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 upload_skill? +

upload_skill is provided by the AI Skill Store MCP server (garasegae/aiskillstore). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
