+# Lannis
+
+Cursor plugin that connects agents to [Lannis](https://lannis.app) through Lannis's hosted [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Issue invoices and track your taxes in Argentina ("Facturá y seguí tus impuestos").
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Lannis**.
+3. Click **Install**, then complete the Lannis sign-in prompt.
+
+Or run `/add-plugin lannis` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "lannis": {
+      "type": "http",
+      "url": "https://mcp.lannis.app/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth. Cursor prompts for Lannis sign-in when the plugin connects — there is no API key to configure.
+
+## Before you connect
+
+You need a Lannis account.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Invoices | List invoices and totals for a period; preview and issue new invoices after you approve them |
+| Taxes | Track tax obligations and generate VEP payment slips to pay at your bank |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- Tool calls run under the Lannis account of the user who authorizes the connection.
+- Issuing an invoice is shown as a preview first and only happens after you approve it.
+
+## Docs
+
+- Lannis: https://lannis.app
+- Server URL: https://mcp.lannis.app/mcp
+
+The logo references the publisher-submitted URL (`https://lannis.app/icon-512.png`). lannis.app could not be reached when this plugin was added, so the file was not committed.
