Demo plugin

This demo plugins extends 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("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

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

<depends>com.intellij.mcpServer</depends>

<extensions defaultExtensionNs="com.intellij.mcpServer">
    <mcpTool implementation="org.jetbrains.mcpextensiondemo.MyCustomTool"/>
</extensions>
