Tools
installmcpconfig
Install an mcp_config.json file into a target tool's configuration directory. It merges the mcpServers object so you don't lose your existing configuration, unless you specify --force.
Arguments
--config: The path to the sourcemcp_config.jsonfile you want to install.--tool: The target tool to install into (windsurf, claude, claude-desktop, opencode, antigravity, devin, codex).--path: (Optional) Explicit custom path to the target configuration file.--force: (Optional) Overwrite existing configuration entirely rather than mergingmcpServers.
Examples
# Install into Windsurf
python scripts/install.py --config ./my_mcp_config.json --tool windsurf
# Install into Antigravity (Agent Utilities XDG dir)
python scripts/install.py --config ./mcp_config.json --tool antigravity
# Install into Claude Code
python scripts/install.py --config /path/to/mcp_config.json --tool claude
# Install into a custom configuration file explicitly
python scripts/install.py --config ./mcp_config.json --path ~/.my_custom_agent/mcp.json
