New tool `mcpward` secures AI agent dependencies against MCP server contract changes

A new tool called `mcpward` has been developed to address the risks associated with changes in MCP (Model Communication Protocol) server contracts, which can silently break agent behavior. Unlike dependency managers that use lockfiles, MCP servers lack versioning and integrity checks, making agents vulnerable to subtle contract modifications. `mcpward` provides two commands: `baseline` to snapshot a server's contract and `diff` to fail CI builds if changes are detected, ensuring agent stability and security. AI

IMPACT Enhances AI agent reliability by preventing silent failures due to MCP server contract drift.
