If you want an AI assistant working directly with Reloaderoo, the reloaderoo mcp server is the bridge. Hot-reload your MCP servers without restarting your AI coding assistant. Works excellently with VSCode MCP, well with Claude Code. A transparent development proxy for the Model Context Protocol that enables seamless server restarts during development.
When developing MCP servers, you typically face two problems: 1. Testing requires complex MCP client setup → CLI mode solves this 2. Code changes require restarting your entire AI session → Proxy mode solves this
Once connected, the assistant can call this tool directly:
Installation — The Installation tool exposed by this serverThe server is distributed via npm as reloaderoo, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
The server reads 8 environment variables: MCPDEV_PROXY_LOG_LEVEL, MCPDEV_PROXY_LOG_FILE, MCPDEV_PROXY_DEBUG_MODE, MCPDEV_PROXY_RESTART_LIMIT, MCPDEV_PROXY_AUTO_RESTART, MCPDEV_PROXY_TIMEOUT, MCPDEV_PROXY_RESTART_DELAY, MCPDEV_PROXY_CWD. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Reloaderoo sits in that group, and the shape of its toolset — Installation — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
