MCP Tool Reference Medium Risk

chat_media_upload

Upload media to a message [write]

Part of the Google Workspace Chat (gws CLI) MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

gws mcp -s chat Write

WHEN AI AGENTS USE THIS TOOL

AI agents use chat_media_upload to create or modify resources in Google Workspace Chat (gws CLI). 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.

WHY ENFORCE A POLICY ON CHAT_MEDIA_UPLOAD

Without a policy, an AI agent could call chat_media_upload 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 Google Workspace Chat (gws CLI).

RECOMMENDED POLICY

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

google-workspace-chat.yaml 
tools:
  chat_media_upload:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60
