+# Ultiwrite
+
+Cursor plugin that connects agents to [Ultiwrite](https://dwsoffshorepartners.com) through Ultiwrite's hosted [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Ultiwrite is an asymmetric diligence engine with document forensics. Upload authorized evidence and receive an investigated, source-backed assessment of what holds up, what does not, and what changes the decision.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Ultiwrite**.
+3. Click **Install**, then complete the Ultiwrite sign-in prompt.
+
+Or run `/add-plugin ultiwrite` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "ultiwrite": {
+      "type": "http",
+      "url": "https://dwsoffshorepartners.com/api/integrations/ultiwrite/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth. Cursor prompts for Ultiwrite sign-in when the plugin connects.
+
+## Before you connect
+
+You need an Ultiwrite account. Sign in at https://engine.dwsoffshorepartners.com.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Evidence | Submit authorized documents and data files for analysis |
+| Reports | Follow processing, then read saved findings and export reports |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- Only upload evidence you are authorized to share.
+- Tool calls run under the Ultiwrite account of the user who authorizes the connection.
