+# UTCP File Plugin
+
+[![PyPI Downloads](https://static.pepy.tech/badge/utcp-file)](https://pepy.tech/projects/utcp-file)
+
+A file-based resource plugin for UTCP. This plugin allows you to define tools that return the content of a specified local file.
+
+## Features
+
+- **Local File Content**: Define tools that read and return the content of local files.
+- **UTCP Manual Discovery**: Load tool definitions from local UTCP manual files in JSON or YAML format.
+- **OpenAPI Support**: Automatically converts local OpenAPI specs to UTCP tools with optional authentication.
+- **Static & Simple**: Ideal for returning mock data, configuration, or any static text content from a file.
+- **Version Control**: Tool definitions and their corresponding content files can be versioned with your code.
+- **No File Authentication**: Designed for simple, local file access without authentication for file reading.
+- **Tool Authentication**: Supports authentication for generated tools from OpenAPI specs via `auth_tools`.
+
+## Installation
+
+```bash
+pip install utcp-file
+```
+
+## How It Works
+
+The File plugin operates in two main ways:
+
+1.  **Tool Discovery (`register_manual`)**: It can read a standard UTCP manual file (e.g., `my-tools.json`) to learn about available tools. This is how the `UtcpClient` discovers what tools can be called.
+2.  **Tool Execution (`call_tool`)**: When you call a tool, the plugin looks at the `tool_call_template` associated with that tool. It expects a `file` template, and it will read and return the entire content of the `file_path` specified in that template.
+
+**Important**: The `call_tool` function **does not** use the arguments you pass to it. It simply returns the full content of the file defined in the tool's template.
+
+## Quick Start
+
+Here is a complete example demonstrating how to define and use a tool that returns the content of a file.
+
+### 1. Create a Content File
+
+First, create a file with some content that you want your tool to return.
+
+`./mock_data/user.json`:
+```json
+{
+  "id": 123,
+  "name": "John Doe",
+  "email": "john.doe@example.com"
+}
+```
+
+### 2. Create a UTCP Manual
+
+Next, define a UTCP manual that describes your tool. The `tool_call_template` must be of type `file` and point to the content file you just created.
+
+`./manuals/local_tools.json`:
+```json
+{
+  "manual_version": "1.0.0",
+  "utcp_version": "1.0.2",
+  "tools": [
+    {
+      "name": "get_mock_user",
+      "description": "Returns a mock user profile from a local file.",
+      "tool_call_template": {
+        "call_template_type": "file",
+        "file_path": "./mock_data/user.json"
+      }
+    }
+  ]
+}
+```
+
+### 3. Use the Tool in Python
+
+Finally, use the `UtcpClient` to load the manual and call the tool.
+
+```python
+import asyncio
+from utcp.utcp_client import UtcpClient
+
+async def main():
+    # Create a client, providing the path to the manual.
+    # The file plugin is used automatically for the "file" call_template_type.
+    client = await UtcpClient.create(config={
+        "manual_call_templates": [{
+            "name": "local_file_tools",
+            "call_template_type": "file",
+            "file_path": "./manuals/local_tools.json"
+        }]
+    })
+
+    # List the tools to confirm it was loaded
+    tools = await client.list_tools()
+    print("Available tools:", [tool.name for tool in tools])
+
+    # Call the tool. The result will be the content of './mock_data/user.json'
+    result = await client.call_tool("local_file_tools.get_mock_user", {})
+
+    print("\nTool Result:")
+    print(result)
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+### Expected Output:
+
+```
+Available tools: ['local_file_tools.get_mock_user']
+
+Tool Result:
+{
+  "id": 123,
+  "name": "John Doe",
+  "email": "john.doe@example.com"
+}
+```
+
+## Use Cases
+
+- **Mocking**: Return mock data for tests or local development without needing a live server.
+- **Configuration**: Load static configuration files as tool outputs.
+- **Templates**: Retrieve text templates (e.g., for emails or reports).
