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

Convert a classification code between UK SIC 2007, GICS (MSCI), and ICB (FTSE Russell) systems. Returns equivalent codes in the target system with confidence levels. The mapping covers all 618 SIC classes, 163 GICS sub-industries, and 173 ICB subsectors.. It is categorised as a Write tool in the Sic Codes MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sic Codes MCP server in PolicyLayer and add a rule for convert_between_classifications: 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 Sic Codes. Nothing to install.
convert_between_classifications 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 convert_between_classifications 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 convert_between_classifications. 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.
convert_between_classifications is provided by the Sic Codes MCP server (jackmmaher/sic-codes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
