"env": {
"TAVILY_API_KEY": "your-key",
"BRAVE_API_KEY": "your-key",

Dynamically enable/disable MCP servers to optimize context usage.
GitHub: https://github.com/spences10/mcpick
Install: npm i -g mcpick
Usage:
mcpick enable omnisearch sqlite-tools
mcpick disable memory-server
mcpick list
Use when: Too many MCPs eating context, need to toggle servers per-project.
| Workflow | Enable | | --------------- | ------------------------------ | | Research | omnisearch | | Data analysis | sqlite-tools | | Full stack | omnisearch + sqlite-tools | | Minimal context | Use mcpick to toggle as needed |
development
Design and create Claude Skills using progressive disclosure principles. Use when building new skills, planning skill architecture, or writing skill content.
testing
Verify sources before presenting findings. Use when asked to research links or documentation.
data-ai
Analyze session history for learnings and persist to skills. Solves "memory zero" - correct once, never again.
tools
Validate, test, and distribute Claude Code plugins and marketplaces. Use when developing plugins, debugging validation errors, or preparing for distribution.
