What is the Reloaderoo MCP server?

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.

What Reloaderoo does

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

Tools it exposes

Once connected, the assistant can call this tool directly:

  • Installation — The Installation tool exposed by this server

Installing the reloaderoo mcp server

The 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.

Configuration

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.

Where it fits

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.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by cameroncooke, written in Python.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the reloaderoo mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
