 An MCP (Model Context Protocol) server that provides access to Tensorlake's document parsing capabilities.
 
+## Features
+
+- **Document Upload**: Upload documents from URLs, local file paths, or data URIs
+- **Document Parsing**: Parse documents into structured data using Tensorlake's AI-powered parsing engine
+- **Document Management**: List and delete documents in your session
+- **MCP Resources**: Access parsed documents as MCP resources for seamless integration
+
+## Prerequisites
+
+- A Tensorlake API key (sign up at [Tensorlake](https://tensorlake.ai))
+- An MCP-compatible host application (e.g., [Claude Desktop](https://claude.ai/download), [Cursor](https://cursor.com), or other MCP hosts)
+
+## Installation
+
+### Install using `go` install
+
+```bash
+go install github.com/sixt/tensorlake-mcp@latest
+```
+
+Locate the binary in your `GOPATH/bin` directory or use the `where` command to find it. For example:
+
+```bash
+$ where tensorlake-mcp
+
+/Users/<username>/go/bin/tensorlake-mcp
+```
+
+### Building from Source
+
+```bash
+# Clone the repository
+git clone <repository-url>
+cd tensorlake-mcp
+
+# Build the server
+go build -o tensorlake-mcp .
+```
+
+The binary will be created as `tensorlake-mcp` in the current directory.
+
+## Configuration
+
+The server requires the following environment variables:
+
+- **`TENSORLAKE_API_KEY`** (required): Your Tensorlake API key
+- **`TENSORLAKE_API_BASE_URL`** (optional): The base URL for the Tensorlake API. Defaults to `https://api.tensorlake.ai/documents/v2`
+
+## Setup
+
+The MCP configuration is:
+
+```json
+{
+  "mcpServers": {
+    "tensorlake-mcp": {
+      "command": "/absolute/path/to/tensorlake-mcp",
+      "env": {
+        "TENSORLAKE_API_KEY": "your-api-key-here"
+      }
+    }
+  }
+}
+```
+
+See these articles for setting up the MCP server in your host application:
+- [Claude Desktop](https://docs.anthropic.com/en/docs/mcp-servers/mcp-servers-claude-desktop)
+- [Claude Code](https://code.claude.com/docs/en/mcp)
+- [Cursor](https://cursor.com/docs/context/mcp)
+- [Other MCP Clients](https://modelcontextprotocol.io/clients)
+
+## Usage
+
+Once configured, the MCP server provides the following tools:
+
+### `upload_document`
+Upload a document from a URL, local path, or data URI.
+
+**Parameters:**
+- `url` (string, required): The URL of the document to upload
+  - URL: `https://example.com/document.pdf`
+  - Local file: `file:///path/to/document.pdf`
+  - Data URI: `data:application/pdf;base64,...`
+
+**Returns:** A `document_id` to be used in subsequent operations
+
+### `parse_document`
+Parse an uploaded document into structured data.
+
+**Parameters:**
+- `document_id` (string, required): The ID returned from `upload_document`
+- `parse_id` (string, optional): The parse ID to check status or get results
+- `sync` (boolean, optional): If true, wait for parsing to complete. If false, start parsing in the background
+
+**Returns:** Parse ID, status, and results (if completed)
+
+### `list_documents`
+List all documents in the current session.
+
+**Returns:** A list of all uploaded documents with their metadata
+
+### `delete_document`
+Delete a document from Tensorlake.
+
+**Parameters:**
+- `document_id` (string, required): The ID of the document to delete
+
+### Resources
+
+The server also exposes a `tensorlake://documents` resource that provides access to all documents and their metadata.
+
+## Example Interaction
+
+```
+User: Upload and parse this PDF document at https://example.com/invoice.pdf
+
+AI: [Uses upload_document tool]
+    [Uses parse_document tool with sync=true]
+    Here's the parsed content from your invoice...
+```
+
+## Development
+
+### Running in Development
+
+```bash
+# Set environment variables
+export TENSORLAKE_API_KEY="your-api-key"
+
+# Run the server
+go build && ./tensorlake-mcp
+```
+
+### Testing with MCP Inspector
+
+You can test the server using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector):
+
+```bash
+npx @modelcontextprotocol/inspector /absolute/path/to/tensorlake-mcp
+```
