Kiro MCP Manager

A VS Code / Kiro IDE extension that provides a full UI for managing MCP (Model Context Protocol) server configurations — no JSON editing required.

Features

• Add, edit, and remove MCP servers through a form-based UI
• Local and remote servers — command-based (stdio) and URL-based (HTTP/SSE)
• Arguments field with shell syntax support and inline/multi-line toggle
• Tool permissions — transfer list UI for auto-approve and disabled tools
• URL reachability check — live indicator for remote server URLs
• Command check — verifies local commands exist in PATH
• MCP server test — sends an MCP initialize handshake to verify connectivity
• Form validation — real-time validation for server names, commands, environment variables, HTTP headers, and tool names
• Auto-refresh — detects external changes to mcp.json and prompts to reload
• Kiro sidebar integration — accessible from the Kiro panel alongside the built-in MCP Servers view
• Config preservation — safely reads/writes mcp.json without clobbering unmanaged sections (e.g., powers)

Usage

1. Open the Kiro sidebar (click the Kiro icon in the activity bar)
2. Find the MCP Manager section and click Open MCP Manager
3. Or use the Command Palette: Ctrl+Shift+P → Kiro MCP: Manage Servers

Development

Prerequisites

• Node.js 22+ (via nvm)
• Kiro IDE

Build and Test

npm install
npm run compile    # Compile extension host + webview TypeScript
npm test           # Compile + run Mocha tests

Deploy

./deploy.sh        # Build, package, install, and notify

Compatibility

This extension is designed for Kiro IDE. It registers a view in the Kiro sidebar panel, which is not available in vanilla VS Code. The core functionality (webview panel, command palette command) works in VS Code, but the sidebar entry point requires Kiro.

The extension reads and writes Kiro's MCP configuration file at ~/.kiro/settings/mcp.json. This path is specific to Kiro and does not exist in standard VS Code installations.
