InterceptPilot

InterceptPilot is a Chrome extension for developers and QA teams who need to inspect, test, and simulate HTTP requests while testing web applications. Inspect request details, create reusable mock rules, and switch between real and mocked API behavior from a focused side panel or the full app. Use InterceptPilot to test loading states, empty states, API errors, rate limits, slow responses, unavailable services, and other edge cases without changing your backend. New in 1.3: AI Bridge (beta). Connect InterceptPilot to your local AI coding agent (Claude Code, Codex, Cursor or any MCP client) and let it read your captured requests, rules and logs, propose mock rules, and control capture, all on your machine, within the permissions you set. Setup takes one copied configuration: open AI Bridge in the full app, click Start, copy the configuration into your MCP client. It runs the open-source interceptpilot-mcp package from npm. Key features: - Inspect HTTP and HTTPS requests from the active tab - Inspect request URLs, methods, status codes, headers, timing, and response details - Create reusable mock rules from captured requests - Enable or disable rules and collections from the side panel - Simulate responses, fail requests, add delays, or pass requests through - Use the full app for advanced rules, diagnostics, import/export, logs, and settings - Copy request details as Fetch or cURL - AI Bridge: let a local AI agent inspect requests, propose and apply mock rules, and start or stop capture, with sanitized data by default and confirmation for every action unless you allow otherwise Privacy: everything stays local. AI Bridge talks to the agent over 127.0.0.1 with a per-session key; nothing is sent to external servers by the extension.
