in Cursor's chat.

1. Get a Loomal API key

Sign up at console.loomal.ai and create an identity. Copy the API key (loid-...).

If you'll use Loomal in multiple projects, mint one identity per project — that way revoking a project's key doesn't take down the others.

# Copy the loid- key from console.loomal.ai → Identity → API Keys

2. Open Cursor's MCP config

Cursor reads MCP servers from one of two places. Project-scoped: .cursor/mcp.json in the repo root. User-scoped: ~/.cursor/mcp.json in your home directory.

Use project-scoped if you want different identities per repo (recommended). Use user-scoped if you want one shared setup across every workspace.

mkdir -p .cursor
$EDITOR .cursor/mcp.json

3. Add Loomal to mcp.json

Add the loomal entry under mcpServers. Paste your API key into LOOMAL_API_KEY. The structure mirrors the Claude Desktop config, which is intentional — both are MCP clients.

{
  "mcpServers": {
    "loomal": {
      "command": "npx",
      "args": ["-y", "@loomal/mcp"],
      "env": {
        "LOOMAL_API_KEY": "loid-your-api-key"
      }
    }
  }
}

4. Reload Cursor's MCP servers

Open Cursor's command palette (Cmd+Shift+P / Ctrl+Shift+P) and run 'MCP: Restart Servers'. The Loomal server starts as a subprocess; tools become available in chat within a couple of seconds.

Open the chat sidebar and check the tools panel — you should see mail.send, mail.list_messages, vault.get, vault.totp, identity.whoami listed under the loomal source.

Cmd+Shift+P → MCP: Restart Servers
Then Cmd+L (Cursor chat) → tools panel → loomal

5. Use the tools in chat

Ask Cursor's chat to do anything that involves your inbox or stored credentials. The model decides which tool to call; the first call per session prompts for permission.

Combined with Cursor's code tools, you can do useful cross-cutting things: 'check my inbox for the latest deploy notification, grab the URL, then open the relevant route file and confirm the change'.

Email the latest type errors to my-manager@example.com — copy from the terminal output above.

Check my inbox for any reply from alice@example.com about the API key change.

What's the current TOTP code for the label 'aws-prod'? I need it for the deploy.

Grab the value of vault label 'github-token' and use it in this curl command.
