Seller Service Metrics API MCP Server

The Seller Service Metrics API is a specialized analytics toolkit designed exclusively for eBay marketplace sellers, provided by eBay's Developer Program.

Quick Start Summary

The Seller Service Metrics API MCP server is a Model Context Protocol bridge that connects AI assistants — including Claude Desktop, Cursor, Windsurf, and VS Code Copilot — to the Seller Service Metrics API API through natural language. It exposes 4 API endpoints as callable tools, such as getCustomerServiceMetric, findSellerStandardsProfiles, getSellerStandardsProfile, and more. No authentication is required — setup takes approximately 30 seconds. The server uses STDIO transport and can be installed by running npx -y @mcp/api-ebay-com-sell-analytics. This integration is sourced from the auto Seller Service Metrics API OpenAPI specification (v1.2.0) and has a quality score of 28/99 (fair documentation coverage).

⚡Capabilities & Use Cases
The Seller Service Metrics API is a specialized analytics toolkit designed exclusively for eBay marketplace sellers, provided by eBay's Developer Program. It serves as a comprehensive performance intelligence layer, enabling sellers to programmatically access and analyze critical data points that directly influence their standing, visibility, and operational efficiency on the platform. The API's core capabilities are structured around three pivotal areas of seller health: customer service performance, seller standards program metrics, and listing traffic analytics. By exposing endpoints such as GET /customer_service_metric, which returns detailed metrics like late shipment rates and issue resolution times, and GET /seller_standards_profile, which outlines a seller's current performance level (e.g., Above Standard, Top Rated), the API allows for granular, data-driven assessment. The GET /traffic_report endpoint further provides insights into listing views and impressions, linking performance metrics directly to visibility. Its typical use cases are enterprise-focused, empowering multi-channel retailers, large-scale eBay dropshippers, and third-party e-commerce management platforms to automate performance monitoring, generate executive dashboards, and proactively identify operational bottlenecks that could lead to account restrictions or reduced search ranking.
🤖AI Agent Value
When exposed as a set of tools via the Model Context Protocol (MCP) to an AI coding assistant like Claude Desktop, Cursor, or Cline, this API transforms from a data endpoint into a proactive analytical partner. The primary value lies in converting raw metric data into actionable, contextual insights through natural language interaction. Instead of a developer manually writing queries, interpreting JSON responses, and calculating trends, an AI agent can ingest this live data to perform complex, synthesis-based analysis. For instance, it can correlate a spike in the "Late Shipment Rate" metric from the customer service endpoint with specific traffic patterns from the /traffic_report endpoint, instantly hypothesizing operational causes. This integration enables the AI to act as a dedicated performance advisor, democratizing access to complex data analysis for developers who may not be data scientists, and drastically reducing the time from data retrieval to insight generation.
💬Example Workflows
Within an MCP-enabled workflow, a developer can instruct the AI agent to execute several powerful dynamic tasks. For example, a user can prompt, "Query my latest customer service metrics and seller standards profile. Analyze if any metrics are trending downward toward the 'Below Standard' threshold over the past three evaluation cycles, and suggest three specific operational changes to improve them." The AI agent would then sequentially call the relevant GET endpoints, parse the historical evaluation data, perform trend analysis, and generate a prioritized action plan. Another practical workflow could be: "Generate a weekly performance summary report by pulling my traffic report and customer service metrics. Automatically draft an email to my operations team highlighting top-performing listings and the customer service issues that need immediate attention, and suggest inventory or support staffing adjustments." This automates a routine managerial task, turning static data retrieval into a continuous intelligence-gathering and recommendation engine.
🛡️Security & Auth
Critical to the secure implementation of this MCP server are robust authentication and authorization practices. Although the described endpoints indicate "None" for authentication in this context, in a real-world scenario, all API calls to eBay's services require an OAuth 2.0 access token with seller-specific scopes. Therefore, the MCP server configuration must securely manage these credentials, never exposing them in plain text. Adherence to the principle of least privilege is paramount: the server should only request the necessary API scopes (e.g., sell.inventory, sell.account) required to fetch the specific metrics being used, avoiding over-privileged tokens. Developers should implement secure secret management for API keys and tokens, enforce HTTPS for all server communications, and consider short-lived tokens for session-based interactions. Furthermore, they should build in data sanitization logic within the MCP tool to handle sensitive performance data responsibly, ensuring any AI-generated outputs or logs do not inadvertently expose confidential business metrics to unauthorized parties.
