get_tour
AI agents call get_tour to retrieve information from Understand-Anything MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description making this harder to assess with full certainty, the tool name 'get_tour' strongly suggests a retrieval operation (guided overview/walkthrough of codebase structure). All sibling tools are read-only queries over a static knowledge graph. There is no indication of data modification, deletion, or execution capability. The server is purely for analysis and understanding, not manipulation.
From the tool's definition Tool name 'get_tour' with empty description; context suggests it retrieves information from a codebase knowledge graph. Sibling tools (find_entry_points, get_class_hierarchy, get_node_detail, get_graph_stats) are all read-only queries.
Attacks that exploit this kind of access
get_tour. It is categorised as a Read tool in the Understand-Anything MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Understand-Anything MCP Server MCP server in PolicyLayer and add a rule for get_tour: 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 Understand-Anything MCP Server. Nothing to install.
get_tour 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_tour 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_tour. 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_tour is provided by the Understand-Anything MCP Server MCP server (viethoangnguyenle/understand-anything-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
