Get workspace storage usage (consumed capacity in bytes).
AI agents call appflowy_get_workspace_usage to retrieve information from AppFlowy MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves read-only information about workspace storage consumption. It performs no modifications, deletions, or side effects—it simply queries and returns existing usage metrics. This is a straightforward data retrieval operation with minimal blast radius if misused by an agent.
From the tool's definition Tool name 'appflowy_get_workspace_usage' and description 'Get workspace storage usage (consumed capacity in bytes)' indicate a retrieval operation that queries current storage metrics without modifying any data.
Attacks that exploit this kind of access
Get workspace storage usage (consumed capacity in bytes). It is categorised as a Read tool in the AppFlowy MCP MCP Server, which means it retrieves data without modifying state.
Register the AppFlowy MCP server in PolicyLayer and add a rule for appflowy_get_workspace_usage: 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 AppFlowy MCP. Nothing to install.
appflowy_get_workspace_usage 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 appflowy_get_workspace_usage 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 appflowy_get_workspace_usage. 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.
appflowy_get_workspace_usage is provided by the AppFlowy MCP server (weironz/appflowy_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
