How to add a server to Cline

one file per user; the extension keeps its own copy of the same list

Open the MCP settings

The extension has a panel for servers; the CLI keeps the same list in a file.

~/.cline/mcp.json

Add the server

For a remote one give its address and pick streamable HTTP — SSE is the legacy path. For a local one give the command.

Pass credentials yourself

There is no OAuth flow here. A server that needs a key takes it from a header or an environment variable you set.

Things that trip people up with Cline

Written from how Cline reads its config, not from its release notes.

No OAuth means part of the catalogue is out of reach

Servers that only accept an interactive login cannot be connected here at all. Ones that take a plain API key work fine — read the catalogue entry before setting anything up.

Extension and CLI keep separate lists

They read the same format but not always the same file. A server added in the editor does not automatically appear in the terminal.

Secrets in the config file

Keys pasted straight into mcp.json sit in plain text. Environment variables are the safer route, especially if the folder is under version control.

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

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

JetBrains AI Assistant

Built into the JetBrains IDEs. Configured through the settings dialog rather than a file, and it can import a config you already wrote for another client.

Settings | Tools | AI Assistant | Model Context Protocol

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
