opencode-mcp-installer

OpenCode TUI plugin that adds /install-mcps and installs MCP server configuration from the official MCP Registry into ~/.config/opencode/opencode.json.

Installation

This is a TUI plugin, so it must be configured in ~/.config/opencode/tui.json.

1. Build the plugin

From this directory:

bun install
bun run fetch-snapshot
bun run build

2. Add it to OpenCode

Add the built file to ~/.config/opencode/tui.json:

{
  "$schema": "https://opencode.ai/tui.json",
  "theme": "system",
  "plugin": [
    "/Users/CTW03903/.config/opencode/plugins/opencode-mcp-installer/dist/tui.js"
  ]
}

3. Restart OpenCode

Restart opencode so the plugin is reloaded.
