Get the hierarchical tree structure of all groups in a workspace
AI agents call get_group_tree to retrieve information from Sidvy MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_group_tree fetches and returns organizational data (group hierarchy) from the Sidvy workspace without creating, modifying, or deleting any resources. This is a read-only retrieval operation with no side effects, making it a Read category tool with low severity.
From the tool's definition Tool name and description indicate retrieval only: 'Get the hierarchical tree structure' — a query operation with no modification, deletion, or execution of commands.
Attacks that exploit this kind of access
Get the hierarchical tree structure of all groups in a workspace. It is categorised as a Read tool in the Sidvy MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sidvy MCP Server MCP server in PolicyLayer and add a rule for get_group_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 Sidvy MCP Server. Nothing to install.
get_group_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_group_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_group_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_group_tree is provided by the Sidvy MCP Server MCP server (martinhjartmyr/sidvy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
