You can now keep a separate set of filtering, highlighting, and traffic modification rules for each project or environment and switch between them in one click.</li><li>Added session import from HAR and SAZ files. You can now open traffic captured by Fiddler Classic or by browser developer tools and inspect it with HTTP Debugger.</li><li>Added an import of Fiddler Classic AutoResponder and Filter rules, and saved Composer requests.</li></ul><h3>Bug Fixes</h3><ul><li>Fixed an HTTPS certificate issue affecting some clients.</li><li>Improved the reliability of saving settings.</li><li>Fixed memory handling and stability issues.</li></ul> https://www.httpdebugger.com/changes#v10-7 httpdebugger-release-10.7 Fri, 07 Aug 2026 00:00:00 GMT <p>MCP server for AI assistants, wider HTTPS capture, and certificate fixes</p><h3>Improvements</h3><ul><li>Added an MCP server.

You can now copy any captured request as a cURL command from the grid context menu.</li><li>HTTPS capture now covers TLS 1.0-only servers and responses that do not fully follow the HTTP spec.</li><li>Added OCSP stapling for intercepted HTTPS. Clients that require a revocation check, such as curl on Windows, can now complete the TLS handshake.</li><li>Updated the capture engine: traffic from 32-bit applications on 64-bit Windows is captured
