Claude Code Inject

Inject hooks, mcps, and default mode into the next claude invocation

Usage

Run this command or create an alias for running claude:

claude-code-inject && claude --mcp-config ./.claude/inject-mcps.json

This will run the claude with any hooks, mcps, and default mode settings present in a user level or project level config file. This is my configuration that 1) Uses hooks to log everything to sqlite and run in yolo mode, 2) includes some generally useful MCPs, and 3) Sets my default mode to plan. The script is careful to not add or change anything that causes a diff in your git repo.

Important note: This approach assumes that you are not using the .claude/ directory of your projects and that you are git ignoring it (in .gitignore or ~/.gitignore_global). claude-code-inject takes control of this directory and leaves it dirty when done. Maybe a more sophisticated approach is possible but for now this shouldn't be used in projects that rely on the contents of .claude/.
