calculate_incentives · Sanka MCP Server MCP: Risk & Policy

WHAT IT DOES

What calculate_incentives does on Sanka MCP Server

AI agents use calculate_incentives to create or update resources in Sanka MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment.

WHY IT NEEDS A POLICY

Why calculate_incentives needs a policy

The tool defaults to a dry run (read-only preview) but can transition to writing state when dry_run=false is set, which stores calculated incentive drafts. This is a reversible modification of data (drafts can be edited or discarded before finalization), making it a Write operation rather than Execute or Destructive.

From the tool's definition The tool 'calculate_incentives' with description states it 'set dry_run=false only when the user explicitly wants drafts stored' — this indicates the tool creates or modifies data (draft incentive records) when dry_run is disabled.

calculate_incentives Rate-limited

calculate_incentives stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Calculate incentives for a period. Defaults to dry_run=true for a safe preview; set dry_run=false only when the user explicitly wants drafts stored. It is categorised as a Write tool in the Sanka MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on calculate_incentives? +

Register the Sanka MCP Server MCP server in PolicyLayer and add a rule for calculate_incentives: 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 Sanka MCP Server. Nothing to install.

What risk level is calculate_incentives? +

calculate_incentives is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit calculate_incentives? +

Yes. Add a rate_limit block to the calculate_incentives 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.

How do I block calculate_incentives completely? +

Set action: deny in the PolicyLayer policy for calculate_incentives. 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.

What MCP server provides calculate_incentives? +

calculate_incentives is provided by the Sanka MCP Server MCP server (sankahq/sanka-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
