GitHub Projects v2 tools not available on hosted endpoint (api.githubcopilot.com/mcp/)

Problem

Issue[ #843] #843 was closed as completed, but the Projects v2 toolset is not available
on the hosted MCP endpoint at https://api.githubcopilot.com/mcp/.

When connecting via any MCP client (tested with multiple MCP clients including VS Code and third-party AI platforms) , no project-related
tools appear. Attempting to activate via ?toolsets=projects query parameter
returns a 400 Bad Request error.

Expected behavior

The projects toolset should be available on the hosted endpoint, either:

• Enabled by default alongside other toolsets
• Activatable via a supported mechanism (header, query param, etc.)

Current behavior

• No project tools listed when connecting to https://api.githubcopilot.com/mcp/
• ?toolsets=projects returns 400 Bad Request
• Custom headers (X-GitHub-Toolsets: projects) have no effect

Context

This blocks AI agent workflows that need to read/write GitHub Projects v2 fields
(Status, Iteration, Size, etc.) without relying on Copilot-proprietary built-in tools.
