~/Library/Application Support/Claude/claude_desktop_config.json  · Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "hubspot-mcp-baryhuang": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-hubspot"
      ],
      "_inferred": true
    }
  }
}

Open Claude Desktop → Settings → Developer → Edit Config. Restart after saving.

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "hubspot-mcp-baryhuang": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-hubspot"
      ],
      "_inferred": true
    }
  }
}

Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

    "hubspot-mcp-baryhuang": {
      "command": "npx",

        "-y",
        "mcp-hubspot"
      ],
      "_inferred": true
    }
  }
}

Click the MCP Servers icon in the Cline sidebar, then "Edit Configuration".

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "hubspot-mcp-baryhuang": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-hubspot"
      ],
      "_inferred": true
    }
  }
}

Same shape as Claude Desktop. Restart Windsurf to pick up changes.

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "hubspot-mcp-baryhuang",
      "command": "npx",
      "args": [
        "-y",
        "mcp-hubspot"
      ]
    }
  ]
}

Continue uses an array of server objects rather than a map.

~/.config/zed/settings.json
{
  "context_servers": {
    "hubspot-mcp-baryhuang": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "mcp-hubspot"
        ]
      }
    }
  }
}

Add to context_servers. Zed hot-reloads on save.

claude mcp add hubspot-mcp-baryhuang -- npx -y mcp-hubspot

One-liner. Verify with claude mcp list. Remove with claude mcp remove.
