See and kill the dev servers your coding agents leave running, and get collision-free ports.

  1. Reads
  2. Writes
  3. High impact

At most: moves money, runs code or commands, deletes data, or sends messages for you.

What it costs

Free

Odel charges nothing per call. The publisher may charge for its own service.

Runs locally over stdio

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).

npm@tidyports/mcpv0.1.2

Run

npx -y @tidyports/mcp

MCP client config

TidyPorts integrations

Let your coding agent see and control the local dev servers it starts.

If you run Claude Code, Cursor or Codex across several git worktrees, each one starts dev servers you never typed a command for. Ports collide, and an agent that hits EADDRINUSE often can't tell a port conflict from a bug — so it "fixes" working code instead.

These integrations give the agent a way to look, rather than guess.

mcp/An MCP server — typed tools for any MCP client (Claude Code, Cursor, Claude Desktop, Windsurf, Zed).
skills/A Claude Code skill, if you'd rather it shelled out to the CLI directly.
guard/Wrap your dev command so EADDRINUSE names what is holding the port, instead of only saying that something is.
raycast/A Raycast extension for the same list, without leaving the launcher.

Tools

ToolWhat it does
list_serversListening dev servers: port, process, branch, owner, idle. Read-only.
kill_portStop the server on a given port.
alloc_portA stable, collision-free port for this worktree — the fix for parallel agents fighting over :3000.
free_portA port nothing is listening on right now, to bind immediately.

Install

The skill, for any agent (Claude Code, Cursor, Copilot, Gemini…):

sh
npx skills add dan-fetch-studio/tidyports-integrations

The MCP server:

sh
npm install -g @tidyports/mcp

Then register it with your client, pointing at the installed tidyports-mcp binary. For Claude Code:

sh
claude mcp add tidyports -- tidyports-mcp

It needs the TidyPorts app

These are a thin layer over the tidy-ports CLI, which ships inside TidyPorts — a free macOS menu-bar app that shows every dev server running on your Mac and which agent started it.

sh
brew install --cask dan-fetch-studio/tap/tidyports

Or download it from tidyports.app/download. macOS 15+.

The integrations here are MIT (see LICENSE). The TidyPorts app itself is source-available under its own licence.
