Mcp status widget

[grandiser]

Description

Adds a docked “MCP Status” panel in Studio with a segmented OFF/ON control that explicitly sets the MCP server connection state.

Rationale

Previously, the plugin button directly toggled the MCP server on and off, with no clear feedback beyond messages in the output terminal. Now, the plugin button controls the visibility of a dedicated panel, where it’s immediately clear whether the server is running or stopped. The terminal output is still present.

This removes ambiguity about the current server state and avoids action/state reversal

Testing Instructions

1. Install/import the plugin in Studio.
2. Open the Plugins tab.
3. Click “MCP Server” to show/hide the panel.
4. Click OFF to stop the server, or ON to start it.
5. Confirm the Output window logs the corresponding start/stop message.

Contribution Guidelines

Please ensure your PR follows these guidelines:

Keep PRs Focused

• Single feature per PR - Each PR should address one specific feature, fix, or improvement
• Keep changes brief and reviewable

For New Tools

When adding a new MCP tool, ensure it meets all of the following criteria:

1. Roblox/Roblox Studio Specific - The tool must provide functionality specific to Roblox or Roblox Studio. Generic tools (e.g., screenshotting, file operations) can be provided by many existing MCP servers and don't belong here.

2. More Efficient Than Running Code - The tool must be more efficient than simply running Luau code in Studio:

   • Do not add tools that wrap 1-2 lines of Luau code
   • Tools are announced with every request and consume context window
   • If you frequently reuse code snippets, add them to an AI instruction file instead

Checklist

• PR addresses a single feature/fix
• Rationale for the change is clearly explained above
• Testing instructions are provided
• (If fixing a bug) Steps to reproduce the original issue are included
• (If adding a tool) Tool is Roblox/Roblox Studio specific
• (If adding a tool) Tool provides significant value over running inline Luau code
