How to add a server to JetBrains AI Assistant

per IDE installation, shared across all open projects
Open the settings page

Tools, then AI Assistant, then Model Context Protocol. No file to find on disk.

Add a server or import one

A remote server needs only its URL. If you already have a working config from another client, the dialog will read it as is.

Check the tool list

The IDE shows what the server exposes once it connects. Empty list with the server marked as added usually means it wants credentials.

Things that trip people up with JetBrains AI Assistant

Written from how JetBrains AI Assistant reads its config, not from its release notes.

No config file to version
Settings live inside the IDE, so a server cannot be committed alongside the project the way it can with a file-based client.
No OAuth flow
Servers that require an interactive login are not reachable here. Ones taking a key in a header are fine.
Same settings across projects
The list belongs to the IDE installation, not to the project. Two projects needing different credentials for one service will collide.

Same servers, other clients

the servers are the same — the config format is not
Windsurf

Editor with the agent built in. Takes stdio, streamable HTTP and SSE, and can carry an OAuth login for each of the three.

~/.codeium/windsurf/mcp_config.json
Cline

Autonomous agent living inside VS Code. Handles local processes and remote endpoints over streamable HTTP or SSE, but authorisation is on you — through headers or environment variables.

~/.cline/mcp.json
Gemini CLI

Google's command-line agent. Takes all three transports and carries a full OAuth flow for remote servers, including service-account impersonation.

~/.gemini/settings.json
OpenCode

Open-source terminal agent. Local and remote servers sit in the same mcp object, told apart by a type field, and tokens are kept outside the config.

opencode.json in the project, or ~/.config/opencode/opencode.json
Claude Code

Adds servers by command, so nothing to edit by hand. Handles both local processes and remote endpoints, including OAuth logins.

run in your terminal
Cursor

Config sits in the project folder, so servers can differ per repository — useful when one project needs database access and another must not have it.

.cursor/mcp.json
VS Code

Works through GitHub Copilot's agent mode. Like Cursor, the config is per workspace rather than global.

.vscode/mcp.json
Codex

The only client here that uses TOML rather than JSON, so a config copied from elsewhere will not work as is.

~/.codex/config.toml
Claude Desktop

One global config for everything, so a server added here is available in every conversation.

~/Library/Application Support/Claude/claude_desktop_config.json
