[BUG] MCP Cannot offload taking up to much space

Environment

• Platform (select one):
• [x ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: <!-- output of claude --version -->
• Operating System: <!-- e.g. macOS 14.3, Windows 11, Ubuntu 22.04 -->
• Terminal: <!-- e.g. iTerm2, Terminal App -->

Bug Description

Issue to Report:

Title: Excessive MCP tools context usage (~32k tokens) cannot be configured or disabled

Description:

• Claude Code automatically loads all MCP tools consuming ~32,197 tokens
• This leaves limited context for actual code and conversation
• Users cannot configure which MCP tools to load
• Unnecessary tools (Puppeteer, Playwright, Lighthouse, Google Drive) are loaded even when not needed for

the project

• This significantly impacts productivity on larger codebases

Impact:

• Reduced working context for code review and development
• Faster context truncation during longer work sessions
• Performance degradation
• No user control over resource allocation

Expected Behavior:
Users should be able to configure which MCP tools to load based on their project needs, similar to VS
Code extensions.

Request:
Add configuration option to selectively enable/disable MCP tools to optimize context usage for specific
project types.

You should report this directly at the GitHub link above. This is definitely a limitation that impacts
development efficiency, especially for larger projects like your IBAM platform.
