AI agents use toreva_perps_add_margin to create or modify resources in Kit. 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 toreva_perps_add_margin 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 Kit.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Add margin to a perpetual futures position. Executes at the position's venue. Value transaction; 2 bps fee applies on the margin value when applicable. Non-custodial.. It is categorised as a Write tool in the Kit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Kit MCP server in PolicyLayer and add a rule for toreva_perps_add_margin: 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 Kit. Nothing to install.
toreva_perps_add_margin 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 toreva_perps_add_margin 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 toreva_perps_add_margin. 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.
toreva_perps_add_margin is provided by the Kit MCP server (@toreva/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
