mcpExtensionPlugin

# Demo plugin This demo plugins extends [JetBrains MCP Server Plugin](https://github.com/JetBrains/mcp-server-plugin) with custom command with arguments. You can use it as a starting point to provide your own tools. ## Important parts: In `build.gradle.kts`: * Add correct dependency on kotlinx.serialization ```kotlin kotlin("jvm") version "1.9.24" kotlin("plugin.serialization") version "1.9.24" ``` This is needed to use the same version of serialization as in the main plugin. * Add dependency on the main plugin ``` dependencies { intellijPlatform { plugin("com.intellij.mcpServer", "1.0.30") } } ``` * Make kotlinx.serialization compileOnly dependendency to avoid runtime errors due to different class loaders of the library ```kotlin dependencies { compileOnly("org.jetbrains.kotlinx:kotlinx-serialization-json:1.6.3") } ``` In `plugin.xml`: * Add the following lines to depend on the plugin and to provide a custom tool ```xml <depends>com.intellij.mcpServer</depends> <extensions defaultExtensionNs="com.intellij.mcpServer"> <mcpTool implementation="org.jetbrains.mcpextensiondemo.MyCustomTool"/> </extensions> ```
