This plugin provides the server-side implementation for handling MCP requests and exposes extension points for implementing custom tools. ## Prerequisites - Installation of [JetBrains MCP Proxy](https://github.com/JetBrains/mcpProxy) - JetBrains IDE (IntelliJ IDEA, WebStorm, etc.) ## Custom Tools Implementation The plugin provides an extension point system that allows third-party plugins to implement their own MCP tools. Here's how to implement and register your custom tools. Refer to the [demo plugin](https://github.com/MaXal/mcpExtensionPlugin) to get started. ### 3. Tool Implementation Guidelines Your tool implementation should follow these guidelines: - Tool names should be descriptive and use lowercase with optional underscores - Create a data class for your tool's arguments that matches the expected JSON input - Use the Response class appropriately: - `Response(result)` for successful operations - `Response(error = message)` for error cases - Use the provided Project instance for accessing IDE services ## How to Publish Update 1. Update `settings.gradle.kts` to provide a new version 2. Create release on Github, the publishing task will be automatically triggered ## Contributing We welcome contributions!
