Compliance API MCP Server

When exposed as a set of tools through the Model Context Protocol (MCP) to an AI coding assistant, the Compliance API gains a transformative, conversational interface. An AI agent like Claude or Cursor can leverage natural language to interact with the complex compliance dataset, making advanced e-commerce governance accessible without requiring the developer to write intricate query logic or remember specific endpoint structures. The value lies in the AI's ability to interpret intent. A developer can simply instruct the AI to "pull all current critical violations for my store," and the AI can map this request to the appropriate GET /listing_violation endpoint with the correct parameters, perhaps filtering by severity. Similarly, asking for a "summary of my listing health over the last 30 days" translates into a call to GET /listing_violation_summary, with the AI potentially suggesting useful parameters for time-range analysis. The POST /suppress_listing_violation endpoint becomes a powerful tool for bulk remediation, where an AI agent can help a developer construct a safe batch operation after confirming which listings to target, drastically reducing the risk of accidental suppression of healthy listings.

Practical workflows for a developer interacting with this MCP server are rich and dynamic. For instance, a developer could instruct: "AI agent, query all my listing violations related to 'prohibited chemicals,' generate a report categorizing them by product category, and list the top three most common violation codes." The AI would execute the GET /listing_violation call with a filter, process the returned data to categorize it, and present the analysis. Another powerful workflow is automation: "AI agent, every night at 9 PM, check for any new 'at-risk' violations for listings created in the last 24 hours and send a Slack notification if any are found." The AI could draft the necessary code for a scheduled job that uses the API to monitor compliance, integrating with other services. Furthermore, for remediation: "AI agent, help me suppress all listings that have been flagged for 'counterfeit goods' suspicion and have more than zero views in the last week." The AI would first verify the list via GET /listing_violation, present it for confirmation, and then execute the POST command to suppress them, ensuring a auditable and controlled action.

Critical to the deployment of this API as an MCP server are significant security considerations, especially given its "no authentication" baseline. This implies the API itself does not issue tokens or manage sessions; access control must be rigorously implemented at the network or server level before the API is ever exposed. Developers must absolutely not expose this endpoint directly to the public internet. The primary security guideline is to implement a robust authentication and authorization proxy. This should involve authenticating all incoming requests to the MCP server using industry-standard methods like OAuth 2.0 or API keys, and then authorizing them against a principle of least privilege. For example, a tool might only be granted the compliance:read scope for querying violations, while a separate, restricted tool would have the compliance:suppress scope. Network security best practices include deploying the server within a private VPC, using firewall rules to whitelist only known AI assistant hosts or developer workstations, and ensuring all communication is encrypted via TLS. Logging all API calls and tool invocations is mandatory for auditing purposes, especially for destructive actions like listing suppression. Developers should also implement rate limiting on their proxy server to prevent abuse and accidental overload of eBay's upstream systems.
