JetBrains MCP Server Plugin

JetBrains MCP (Model Context Protocol) Server Plugin enables seamless integration between Large Language Models (LLMs) and JetBrains IDEs. This plugin provides the server-side implementation for handling MCP requests and exposes extension points for implementing custom tools.

Prerequisites

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 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

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
