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

Check if your current changes can merge cleanly with other agents' work. Call before finalizing edits to catch conflicts early.. It is categorised as a Write tool in the Kai MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Kai MCP server in PolicyLayer and add a rule for kai_merge_check: 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 Kai. Nothing to install.
kai_merge_check 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 kai_merge_check 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 kai_merge_check. 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.
kai_merge_check is provided by the Kai MCP server (kai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
