Excessive context usage for tools

[rcdailey]

I went from 34k tokens to 80k tokens just by adding the github mcp to Claude Code. Even though I am specifying an explicit toolset representing only things I'd use on a day to day basis as a developer, there are over 66 tools!

My MCP registration in Claude Code:

"github": {
  "type": "http",
  "url": "https://api.githubcopilot.com/mcp",
  "headers": {
    "Authorization": "Bearer SNIP",
    "X-MCP-Toolsets": "context,orgs,repos,issues,pull_requests,actions,discussions,actions"
  }
}

Before I added Github MCP:

And after:

I really want to use this MCP server because claude is so much more efficient with it than the gh CLI. However, being able to use nearly only half of Claude 4.5's available context for a single MCP tool is just too much for me.

I was really hoping this was optimized but it doesn't seem so. I hope the team can address the volume of tools soon. I think some consolidation is desperately needed.
