get_vertex_valence
AI agents call get_vertex_valence to retrieve information from BlenderMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Vertex valence is a read-only geometric property of mesh topology. Retrieving this value does not modify, delete, or execute operations—it simply queries existing mesh data. This is a classic Read operation with minimal risk if misused, as it cannot cause damage or unintended side effects to the scene.
From the tool's definition Tool name 'get_vertex_valence' indicates a query operation that retrieves the valence (degree/count of edges connected) of a vertex in a 3D mesh. The '_valence' suffix and 'get_' prefix strongly suggest data retrieval with no side effects.
Attacks that exploit this kind of access
get_vertex_valence. It is categorised as a Read tool in the BlenderMCP MCP Server, which means it retrieves data without modifying state.
Register the Blender MCP server in PolicyLayer and add a rule for get_vertex_valence: 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 BlenderMCP. Nothing to install.
get_vertex_valence 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_vertex_valence 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_vertex_valence. 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_vertex_valence is provided by the Blender MCP server (shirshovdim/retopoflow_blender_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
