About this plugin
MCP Tracker is an admin-only WordPress plugin designed to monitor and log MCP (Model Context Protocol) requests made to the Abilities API on your WordPress site.
If you are using the Abilities API to power AI-driven tools or MCP-based integrations, MCP Tracker gives you complete visibility into how those tools interact with your REST endpoints — without modifying or interfering with request flow.
The plugin automatically detects MCP requests (identified via the Mcp-Session-Id header), records detailed request and response data, and presents everything in a structured, filterable interface inside WordPress Admin.
Whether you’re debugging Abilities API integrations, auditing MCP tool usage, or analyzing response behavior, MCP Tracker provides the observability layer you need.
