Clarification on MCP connector version

The MCP Connector version 1.0.0, which was officially released on July 10, 2025, has raised a question regarding its underlying specification compliance. Specifically, there is uncertainty about which version of the Model Context Protocol (MCP) specification this connector implements. The possible specifications under consideration are:

• MCP Spec version 2025-06-18

• MCP Spec version 2025-03-26

• MCP Spec version 2024-11-05

This query is particularly important in light of a critical remote code execution vulnerability that was publicly disclosed on July 10, 2025, affecting earlier implementations of the MCP protocol. According to the report published by The Hacker News (link), this vulnerability impacts MCP servers and clients that do not fully comply with the latest security measures introduced in the June 18, 2025 spec update.

Given the timing of the connector's release, there is a need to confirm whether MCP Connector v1.0.0 adheres to the latest specification (2025-06-18), which includes the necessary security enhancements to mitigate this vulnerability.

For reference, the official MCP specification for June 18, 2025 can be reviewed here:
