What's New in ProxyPin

1.3.3

September 29, 2026

Bug fixes: - Fixed an issue where HTTPS request bodies could be lost after a CONNECT tunnel was established What's New: 1. Added a built-in MCP server so AI assistants (e.g. Claude) can inspect and debug captured traffic; 2. Added built-in dynamic variables for environments; 3. Request rewrite rules can now be reordered with move up/down actions; 4. Fixed a crash triggered by the Windows context menu; 5. Fixed multi-value headers (e.g. multiple Set-Cookie) being incorrectly merged when handled by scripts or rewrite rules; 6. Fixed h2c (plaintext HTTP/2) capture, non-ASCII domain normalization, and certificate validation failures for IP hosts; 7. Fixed an iOS 13 crash, dropped bodies for close-delimited responses
