AI agents call lookup_corp_code to retrieve information from Koreanpulse without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though lookup_corp_code only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Korean company name → DART corp_code resolver. 117K+ entities indexed (KOSPI + KOSDAQ + KONEX + unlisted). Free tier. Use this tool when the user mentions a Korean company by name (Korean characters or English/romanized) and you need the DART corp_code as a precondition for track_korean_filings, monitor_activist_investors, or monitor_foreign_holders. Also use to disambiguate same-name listed vs unlisted entities.. It is categorised as a Read tool in the Koreanpulse MCP Server, which means it retrieves data without modifying state.
Register the Koreanpulse MCP server in PolicyLayer and add a rule for lookup_corp_code: 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 Koreanpulse. Nothing to install.
lookup_corp_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the lookup_corp_code 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 lookup_corp_code. 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.
lookup_corp_code is provided by the Koreanpulse MCP server (https://mcp.koreanpulse.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
