AI agents invoke call_taxlaw_extra to trigger actions in Taxlaw Nts. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool acts as a gateway/dispatcher that routes to various sub-tools based on the 'name' argument. While many sub-tools appear to be read/query operations (lookups, searches, text retrieval), the dispatcher pattern with arbitrary argument objects means it can trigger a range of operations including computations (compute_employment_credit).
From the tool's definition '저빈도 도구 게이트웨이' (low-frequency tool gateway) that dispatches to multiple sub-tools by name with arbitrary args; includes compute_employment_credit calculations, industry classification, and document retrieval operations

It is categorised as a Execute tool in the Taxlaw Nts MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Taxlaw Nts MCP server in PolicyLayer and add a rule for call_taxlaw_extra: 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 Taxlaw Nts. Nothing to install.
call_taxlaw_extra is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the call_taxlaw_extra 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 call_taxlaw_extra. 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.
call_taxlaw_extra is provided by the Taxlaw Nts MCP server (kim-go-chon/taxlaw-nts-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
