Returns the tab tree (Windows → Groups → Tabs) from the Pinako extension. Three legacy modes (prefer composable shape opts — see SHAPE COMPOSITION below):
AI agents call get_tree to retrieve information from Pinako AI Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organizational metadata about open tabs, windows, and groups from the extension. It has no side effects, does not modify data, execute code, delete anything, or move money. It is a straightforward read operation that returns structured data about the user's current browser state.
From the tool's definition Tool name 'get_tree' and description 'Returns the tab tree' indicate data retrieval with no modification or execution. The verb 'Returns' is passive and retrieves existing browser state (Windows, Groups, Tabs) from the Pinako extension.

Returns the tab tree (Windows → Groups → Tabs) from the Pinako extension. Three legacy modes (prefer composable shape opts — see SHAPE COMPOSITION below):. It is categorised as a Read tool in the Pinako AI Bridge MCP Server, which means it retrieves data without modifying state.
Register the Pinako AI Bridge MCP server in PolicyLayer and add a rule for get_tree: 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 Pinako AI Bridge. Nothing to install.
get_tree 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 get_tree 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 get_tree. 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.
get_tree is provided by the Pinako AI Bridge MCP server (teleomorph/pinako-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
