Claude Code extension manager â MCP servers, plugins (skills, hooks, agents), and marketplaces.
Use mcpick inline in Claude Code sessions. Tell Claude:
Use npx mcpick to add the marketplace at spences10/claude-code-toolkit
Use npx mcpick to list my plugins and disable the ones I'm not using
Use npx mcpick to enable only the mcp-sqlite-tools server
McPick auto-detects non-TTY environments and shows structured help
instead of launching the interactive TUI â so LLM agents can read
npx mcpick --help and figure out the rest.
Marketplaces contain plugins. Plugins contain skills
(/slash-commands), hooks, agents, and MCP servers.
Marketplace â Plugin â Skills, Hooks, Agents, MCP Servers
# 1. Add the marketplace
npx mcpick marketplace add spences10/claude-code-toolkit
# 2. Install a plugin from it
npx mcpick plugins install my-plugin@claude-code-toolkit
# 3. Skills are now available as /slash-commands in Claude CodeMarketplace sources can be:

menu for human use:
â MCPick - Claude Code Extension Manager

In non-TTY environments (LLM agents, piped output), mcpick
automatically shows --help instead.
Claude Code loads all MCP servers at startup. With many servers
configured, /doctor shows:
Context Usage Warnings
â â Large MCP tools context (~66,687 tokens > 25,000)
This means slower startup, wasted context tokens, and cognitive overload from too many tools. McPick lets you toggle servers on/off so you only load what you need.
