What it does

Periscope MCP is a specialized Model Context Protocol server designed to enable AI agents to perform comprehensive website and web application testing. Unlike raw browser bindings, it provides 66 purpose-built Playwright tools that include hard assertions, automatic form filling, persistent authenticated sessions with support for 2FA/SSO, network mocking, real INP measurement, and accessibility testing.

How to set up

Install the segentic-lab/periscope-mcp package from the repository. Configure it as an MCP server in your AI platform (Claude, ChatGPT, or other supported platforms). Authenticate with your target websites and establish persistent sessions through the tool's built-in session management. The interactive login feature handles complex authentication scenarios including two-factor authentication and single sign-on flows.
