Adding the Ezurio MCP Server to Cursor

Adding the Ezurio MCP Server to Cursor

Prerequisites:

  • Cursor IDE version 0.40 or later.
  • Node.js 18 or higher, npx in the path
  • An account at www.ezurio.com.

Overview

Cursor can connect to remote MCP servers over Streamable HTTP. You can configure Cursor using the built-in UI or by editing the ~/.cursor/mcp.json file directly with the settings presented below.

Using the Cursor Settings UI

Step 1 – Open Cursor Settings

  1. Open Cursor.
  2. Press Cmd+, (macOS) or Ctrl+, (Windows/Linux) to open Settings.
  3. Navigate to Tools & MCPs.

Step 2 – Add a New MCP Server

  1. Click Home
  2. In the Home MCP Servers section, click Add Custom MCP
  3. This opens the mcp.json file for editing. Add an entry for ezurio-mcp:
    {
      "mcpServers": {
        "ezurio-mcp": {
          "command": "npx",
          "args": ["-y", "mcp-remote", "https://mcp.ezurio.com/ez/mcp"]
        }
      }
    }
  4. Save the file
  5. A browser window opens and presents the OAuth dialog. If the browser does not appear, press the Connect button. Follow the prompts to authorize use of the tools.

Step 3 – Verify the Connection

  1. Return to Settings → Tools & MCPs.
  2. Find ezurio-mcp in the server list.
  3. A green dot next to the server name indicates a successful connection. A red dot means the connection failed; double-check the URL and make sure you are logged into your account at www.ezurio.com.

Step 4 – Verify Tool Availability in Agent Mode

  1. Open the Chat panel in Cursor.
  2. Switch to Agent mode.
  3. Make a request that would require an Ezurio MCP tool, or ask the agent to list available tools.
  4. Cursor's Agent will automatically invoke the MCP tools from the Ezurio MCP server as needed.

MCP tools are available in Cursor's Agent (chat) mode only. They are not available in autocomplete or inline code edits.

Troubleshooting

SymptomResolution
Red dot / server not connectingVerify the URL is correct; confirm network access to the server; check for JSON syntax errors in the config file
MCP server not appearing after addingFully quit and reopen Cursor; MCP servers load at startup only
Tools not available in chatConfirm you are in Agent mode, not standard chat mode; check that the server shows a green dot in Settings → Tools & MCPs
JSON config not loadingValidate your JSON syntax — a missing comma or bracket causes the entire config to fail silently.
