AI agents use plate_loader to create or modify resources in CoachSync. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call plate_loader repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach CoachSync.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access plate_loader gives an agent. Each links to the full case and the policy that stops it:

Calculate which plates to load on each side of the barbell to reach a target weight. Supports custom bar weights and custom plate inventories for home gyms. Powered by CoachSync.io.. It is categorised as a Write tool in the CoachSync MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CoachSync MCP server in PolicyLayer and add a rule for plate_loader: 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 CoachSync. Nothing to install.
plate_loader is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the plate_loader 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 plate_loader. 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.
plate_loader is provided by the CoachSync MCP server (https://mcp.coachsync.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
