AI agents call plane-page-detail to retrieve information from Plane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing page data and renders it as HTML for display. There are no side effects, no data creation or modification, no code execution, and no destructive operations. It is a straightforward read-only query operation consistent with the Read category.
From the tool's definition Tool description states 'Get page metadata AND readable HTML content' — the verb 'Get' and phrase 'readable' (not writable) indicate a retrieval operation with no modifications.
Attacks that exploit this kind of access
Get page metadata AND readable HTML content. Returns the page object with description_html (the actual content), not the Yjs binary. It is categorised as a Read tool in the Plane MCP Server, which means it retrieves data without modifying state.
Register the Plane MCP server in PolicyLayer and add a rule for plane-page-detail: 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 Plane. Nothing to install.
plane-page-detail 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 plane-page-detail 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 plane-page-detail. 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.
plane-page-detail is provided by the Plane MCP server (philipvanlewis/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
