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
