获取总延迟（秒）
AI agents call vicon_get_latency_total 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 latency measurements from the Vicon motion capture system. It is a read-only diagnostic query that has no side effects, does not modify data, does not execute commands, and does not create or delete resources. The information returned is used for monitoring system performance. This is a classic 'Read' category operation with minimal security risk.
From the tool's definition Tool name 'vicon_get_latency_total' and description '获取总延迟（秒）' (Get total latency in seconds) indicate a retrieval operation that queries system performance metrics without modifying state or triggering external operations.
Attacks that exploit this kind of access
获取总延迟（秒）. 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_latency_total: 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_latency_total 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_latency_total 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_latency_total. 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_latency_total 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.
