Resolve a CBSA (Core Based Statistical Area) code to its metro area name. CBSA codes appear in spend signals and distribution data as 5-digit codes (e.g. '35620'). This tool converts them to human-readable names (e.g. '35620' → 'New York-Newark-Jersey City, NY-NJ'). Also handles non-metro codes l...

AI agents use resolve-cbsa to create or modify resources in Crinkl Commerce MCP. 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 resolve-cbsa 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 Crinkl Commerce MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Resolve a CBSA (Core Based Statistical Area) code to its metro area name. CBSA codes appear in spend signals and distribution data as 5-digit codes (e.g. '35620'). This tool converts them to human-readable names (e.g. '35620' → 'New York-Newark-Jersey City, NY-NJ'). Also handles non-metro codes like 'non-metro:US-TN'.. It is categorised as a Write tool in the Crinkl Commerce MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Crinkl Commerce MCP server in PolicyLayer and add a rule for resolve-cbsa: 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 Crinkl Commerce MCP. Nothing to install.
resolve-cbsa 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 resolve-cbsa 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 resolve-cbsa. 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.
resolve-cbsa is provided by the Crinkl Commerce MCP server (https://mcp.crinkl.xyz/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
