Useful MCP listing: JetBrains IDE Index is the kind of server we cite when onboarding engineers to host + tool permissions.
Strong directory entry: JetBrains IDE Index surfaces stars and publisher context so we could sanity-check maintenance before adopting.
We evaluated JetBrains IDE Index against two servers with overlapping tools; this profile had the clearer scope statement.
I recommend JetBrains IDE Index for teams standardizing on MCP; the explainx.ai page compares cleanly with sibling servers.
According to our notes, JetBrains IDE Index benefits from clear Model Context Protocol framing — fewer ambiguous “AI plugin” claims.
JetBrains IDE Index reduced integration guesswork — categories and install configs on the listing matched the upstream repo.
We wired JetBrains IDE Index into a staging workspace; the listing’s GitHub and npm pointers saved time versus hunting across READMEs.

A JetBrains IDE plugin that exposes an MCP (Model Context Protocol) server, enabling AI coding assistants like Claude, Codex, Cursor, and Windsurf to leverage the IDE's powerful indexing and refactoring capabilities.
Fully tested: IntelliJ IDEA, PyCharm, WebStorm, GoLand, RustRover, Android Studio, PhpStorm May work (untested): RubyMine, CLion, DataGrip
IDE Index MCP Server provides AI coding assistants with access to the IDE's powerful code intelligence features through the Model Context Protocol (MCP).
Multi-Language Support Advanced tools work across multiple languages based on available plugins:
Universal Tools (All JetBrains IDEs)
Extended Tools (Language-Aware) These tools activate based on installed language plugins:
Refactoring Tools
Unlike simple text-based code analysis, this plugin gives AI assistants access to:
Perfect for AI-assisted development workflows where accuracy and safety matter.

intellij-index on port 29170pycharm-index on port 29172webstorm-index on port 29173The easiest way to configure your AI assistant:
Use the "Install on Coding Agents" button in the tool window, or run this command (adjust name and port for your IDE):
# IntelliJ IDEA
claude mcp add --transport http intellij-index http://127.0.0.1:29170/index-mcp/sse --scope user
# PyCharm
claude mcp add --transport http pycharm-index http://127.0.0.1:29172/index-mcp/sse --scope user
# WebStorm
claude mcp add --transport http webstorm-index http://127.0.0.1:29173/index-mcp/sse --scope user
Options:
--scope user - Adds globally for all projects--scope project - Adds to current project onlyTo remove: claude mcp remove <server-name> (e.g., claude mcp remove intellij-index)
Use the "Install on Coding Agents" button in the tool window, or run this command (adjust name and port for your IDE):
# IntelliJ IDEA
codex mcp add --transport sse intellij-index http://127.0.0.1:29170/index-mcp/sse
# PyCharm
codex mcp add --transport sse pycharm-index http://127.0.0.1:29172/index-mcp/sse
# WebStorm
codex mcp add --transport sse webstorm-index http://127.0.0.1:29173/index-mcp/sse
To remove: codex mcp remove <server-name> (e.g., codex mcp remove intellij-index)
Add to .cursor/mcp.json in your project root or ~/.cursor/mcp.json globally (adjust name and port for your IDE):
{
"mcpServers": {
"intellij-index": {
"url": "http://127.0.0.1:29170/index-mcp/sse"
}
}
}
Add to ~/.codeium/windsurf/mcp_config.json (adjust name and port for your IDE):
{
"mcpServers": {
"intellij-index": {
"serverUrl": "http://127.0.0.1:29170/index-mcp/sse"
}
}
}
{
"mcp.servers": {
"intellij-index": {
"transport": "sse",
"url": "http://127.0.0.1:29170/index-mcp/sse"
}
}
}
Note: Replace the server name and port with your IDE's defaults. See IDE-Specific Defaults below.
Each JetBrains IDE has a unique default port and server name to allow running multiple IDEs simultaneously without conflicts:
| IDE | Server Name | Default Port |
|---|---|---|
| IntelliJ IDEA | intellij-index | 29170 |
| Android Studio | android-studio-index | 29171 |
| PyCharm | pycharm-index | 29172 |
| WebStorm | webstorm-index | 29173 |
| GoLand | goland-index | 29174 |
| PhpStorm | phpstorm-index | 29175 |
| RubyMine | rubymine-index | 29176 |
| CLion | clion-index | 29177 |
| RustRover | rustrover-index | 29178 |
| DataGrip | datagrip-index | 29179 |
| Aqua | aqua-index | 29180 |
| DataSpell | dataspell-index | 29181 |
| Rider | rider-index | 29182 |
Tip: Use the "Install on Coding Agents" button in the tool window - it automatically uses the correct server name and port for your IDE.

✗ Don't
💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
