获取相机质心数据
AI agents call vicon_get_centroids to retrieve information from Vicon DataStream MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves kinematic data (centroids) from Vicon motion capture cameras. It performs a read-only query operation that streams or fetches existing data without side effects. No data is created, modified, deleted, or any external operations triggered. This is a standard data retrieval function typical of motion capture system monitoring.
From the tool's definition Tool name 'vicon_get_centroids' and description '获取相机质心数据' (retrieve camera centroid data) indicate data retrieval. The function retrieves centroid data from motion capture cameras with no modification, deletion, or code execution.
Attacks that exploit this kind of access
获取相机质心数据. It is categorised as a Read tool in the Vicon DataStream MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vicon DataStream MCP Server MCP server in PolicyLayer and add a rule for vicon_get_centroids: 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 Vicon DataStream MCP Server. Nothing to install.
vicon_get_centroids 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 vicon_get_centroids 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 vicon_get_centroids. 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.
vicon_get_centroids is provided by the Vicon DataStream MCP Server MCP server (ros-claw/vicon-datastream-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
