MCP Peek

MCP Peek is a desktop workspace that puts every MCP server under a microscope. Connect any server (stdio or HTTP/SSE), see its full catalog of tools, resources, and prompts with what each one costs in tokens, and run them through forms generated from their schemas. Then point Claude or Cursor at the built-in proxy and it traces every call your agent makes — the exact request, response, timing, and token count. All local; nothing leaves your machine. Free on one server; $19 once for the proxy and unlimited servers.
