Developer tool for inspecting, testing, and debugging WebMCP tools WebMCP Inspector is a developer-focused Chrome extension that makes WebMCP tooling visible and actionable inside the browser. It detects WebMCP APIs on the current page, lists available tools, shows input schemas, and lets you execute tools instantly with JSON inputs. You can also use AI chat (Gemini, OpenAI, Anthropic, or Ollama) to run multi-step tool workflows faster. Why install it: Build and debug WebMCP integrations without guesswork Validate tool schemas and arguments before production use Quickly reproduce and diagnose tool execution issues Refresh and inspect dynamically registered tools in real time Speed up testing with both manual and AI-assisted execution in one UI If you’re building WebMCP-enabled apps, this extension gives you a practical inspector and test bench directly in Chrome.
