AI agents call get_mocap_sample to retrieve information from RTK Motion — Motion Capture, Biomechanics, and Threat Intelligence without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_mocap_sample only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREE motion capture sample — first 5 seconds of BVH skeletal animation (frame count = 5 × lesson fps). Enough to validate format, joint hierarchy, and data quality for sim_to_real_retargeting or action_recognition. Full files are 20–120 seconds ($10 USDC via get_bvh).. It is categorised as a Read tool in the RTK Motion — Motion Capture, Biomechanics, and Threat Intelligence MCP Server, which means it retrieves data without modifying state.
Register the RTK Motion — Motion Capture, Biomechanics, and Threat Intelligence MCP server in PolicyLayer and add a rule for get_mocap_sample: 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 RTK Motion — Motion Capture, Biomechanics, and Threat Intelligence. Nothing to install.
get_mocap_sample 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_mocap_sample 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_mocap_sample. 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_mocap_sample is provided by the RTK Motion — Motion Capture, Biomechanics, and Threat Intelligence MCP server (https://api.rtkmotion.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
