v1.2.0

Add MCP tools to linked ChatGPT conversations through a message-based tool loop, available through the compatible clients and proxy.

Features

• Connect reusable stdio, Streamable HTTP and legacy SSE MCP servers with independent connection settings.
• Adapt tool requests and results into conversation turns, filtering control traffic from the completion text returned to applications.
• Preserve conversation context through multiple tool rounds and typed SSE streaming.

Controls and validation

• Apply tool allowlists, approval callbacks, size/count limits, timeouts and per-user proxy permissions.
• Record uncertain tool outcomes so recovery does not blindly execute an operation again.
• Expand integration coverage with real fixture processes, HTTP/SSE servers, cancellation and browser bundle checks.
