Claude Desktop

(claude_desktop_config.json)

{
    "mcpServers": {
        "local-marketplace-yopmail-mcp-server-demo-stdio": {
            "command": "npx",
            "args": [
                "npx",
                "@modelcontextprotocol/server-filesystem",
                "/tmp"
            ]
        }
    }
}

Add it manually

Open the config file. macOS: ~/Library/Application Support/Claude/claude_desktop_config.json. Windows: %APPDATA%\Claude\claude_desktop_config.json. Or use Settings → Developer → Edit Config in the app.
Merge the snippet above into mcpServers. Keep any existing servers in place.
Save the file and restart Claude Desktop.

Claude Code

(CLI)

claude mcp add 'local-marketplace-yopmail-mcp-server-demo-stdio' -- 'npx' 'npx' '@modelcontextprotocol/server-filesystem' '/tmp'

Add it manually

Run the command above in your terminal — it registers this server with claude mcp add. Same on macOS and Windows.
Verify with claude mcp list.
New Claude Code sessions pick it up automatically — no restart needed.

Cursor

(~/.cursor/mcp.json)

Add to Cursor

{
    "mcpServers": {
        "local-marketplace-yopmail-mcp-server-demo-stdio": {
            "command": "npx",
            "args": [
                "npx",
                "@modelcontextprotocol/server-filesystem",
                "/tmp"
            ]
        }
    }
}

Add it manually

Click Add to Cursor above for a one-click install. Or open the config file by hand — macOS: ~/.cursor/mcp.json. Windows: %USERPROFILE%\.cursor\mcp.json. Create the file if it does not exist.
Merge the snippet above into mcpServers.
Restart Cursor so the new server loads.

VS Code

(.vscode/mcp.json)

{
    "servers": {
        "local-marketplace-yopmail-mcp-server-demo-stdio": {
            "command": "npx",
            "args": [
                "npx",
                "@modelcontextprotocol/server-filesystem",
                "/tmp"
            ]
        }
    }
}

Add it manually

In your workspace, create .vscode/mcp.json if it does not exist (same path on macOS and Windows — it is relative to the project root).
Merge the snippet above into servers.
Reload the window: Cmd + Shift + P (macOS) or Ctrl + Shift + P (Windows) → Developer: Reload Window. Requires the MCP extension to be enabled.

{
    "mcpServers": {
        "local-marketplace-yopmail-mcp-server-demo-stdio": {
            "command": "npx",
            "args": [
                "npx",

                "/tmp"
            ]
        }
    }
}

Add it manually

Open the config file. macOS: ~/.codeium/windsurf/mcp_config.json. Windows: %USERPROFILE%\.codeium\windsurf\mcp_config.json. Create it if missing.
Merge the snippet above into mcpServers.
Restart WindSurf.

Continue.dev

(~/.continue/config.json)

{
    "mcp": {
        "servers": {
            "local-marketplace-yopmail-mcp-server-demo-stdio": {
                "command": "npx",
                "args": [
                    "npx",
                    "@modelcontextprotocol/server-filesystem",
                    "/tmp"
                ]
            }
        }
    }
}

Add it manually

Open the config file. macOS: ~/.continue/config.json. Windows: %USERPROFILE%\.continue\config.json.
Merge the snippet above into mcp.servers.
Reload Continue from its sidebar menu, or restart your editor.

Zed

(settings.json)

{
    "context_servers": {
        "local-marketplace-yopmail-mcp-server-demo-stdio": {
            "command": "npx",
            "args": [
                "npx",
                "@modelcontextprotocol/server-filesystem",
                "/tmp"
            ]
        }
    }
}

Add it manually

Open settings. In the app: Command Palette → zed: open settings. By path — macOS: ~/.config/zed/settings.json. Windows: %APPDATA%\Zed\settings.json.
Merge the snippet above into context_servers.
Save — Zed picks it up live, no restart needed.

Raw curl

(HTTP transports)

# server.json declares no remote HTTP endpoint yet.

Add it manually

Run the command above in your terminal. It performs a tools/list handshake against the server.
Replace $TOKEN with your bearer token if the server requires authentication.
A successful response confirms the endpoint is reachable before you wire the server into a real client.
