Adding the Ezurio MCP Server to Cursor
Prerequisites:
- Cursor IDE version 0.40 or later.
- Node.js 18 or higher,
npxin 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
- Open Cursor.
- Press
Cmd+,(macOS) orCtrl+,(Windows/Linux) to open Settings. - Navigate to Tools & MCPs.
Step 2 – Add a New MCP Server
- Click Home
- In the Home MCP Servers section, click Add Custom MCP
- This opens the
mcp.jsonfile for editing. Add an entry forezurio-mcp:{ "mcpServers": { "ezurio-mcp": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.ezurio.com/ez/mcp"] } } } - Save the file
- 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
- Return to Settings → Tools & MCPs.
- Find ezurio-mcp in the server list.
- 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
- Open the Chat panel in Cursor.
- Switch to Agent mode.
- Make a request that would require an Ezurio MCP tool, or ask the agent to list available tools.
- 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
| Symptom | Resolution |
|---|---|
| Red dot / server not connecting | Verify the URL is correct; confirm network access to the server; check for JSON syntax errors in the config file |
| MCP server not appearing after adding | Fully quit and reopen Cursor; MCP servers load at startup only |
| Tools not available in chat | Confirm you are in Agent mode, not standard chat mode; check that the server shows a green dot in Settings → Tools & MCPs |
| JSON config not loading | Validate your JSON syntax — a missing comma or bracket causes the entire config to fail silently. |
