⚠️ PRE RELEASE⚠️

This release migrates the GitHub MCP Server from mark3labs/mcp-go to the official modelcontextprotocol/go-sdk library. While the changes are primarily structural—focused on tool schema syntax rather than behavioral changes—the migration touches a significant amount of code.

We're looking for community testing before promoting this to a stable release. If you encounter any issues, please report them in thediscussions thread.

Default Toolset Configuration#1229

Default toolsets were introduced in the previous release. To make configuration easier, theX-MCP-Toolsets header (for Remote) and--toolsets CLI arg (for Local) now accept thedefault toolset string. This can be used to add to the default toolsets without explicitly naming each one.

Examples:

• "default"
  Instead of:"context,repos,issues,pull_requests,users"
• "default,discussions"
  Instead of:"context,repos,issues,pull_requests,users,discussions"
