AI agents use keka_apply_leave to create or modify resources in Keka HR Integration Server. 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 keka_apply_leave 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 Keka HR Integration Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access keka_apply_leave gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Apply for leave for an employee. It is categorised as a Write tool in the Keka HR Integration Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Keka HR Integration Server MCP server in PolicyLayer and add a rule for keka_apply_leave: 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 Keka HR Integration Server. Nothing to install.
keka_apply_leave 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 keka_apply_leave 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 keka_apply_leave. 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.
keka_apply_leave is provided by the Keka HR Integration Server MCP server (KaranThink41/keka_official_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
