# TradingView PineScript MCP Server A Model Context Protocol (MCP) server for working with TradingView PineScript. This server provides tools for validating, fixing, and generating PineScript code through a standardized API. ## Features - **PineScript Validation** - Automatically validates PineScript code for syntax errors and warnings - **Error Fixing** - Automatically fixes common PineScript syntax errors - **Template Generation** - Provides validated templates for various PineScript strategies and indicators ## Getting Started ### Prerequisites - Node.js 16.x or higher - npm 8.x or higher ### Installation 1. Clone the repository ```bash git clone https://github.com/yourusername/pinescriptproject1.git cd pinescriptproject1 ``` 2. Install dependencies ```bash npm install ``` 3. Build the project ```bash npm run build ``` ### Running the Server Start the MCP server: ```bash npm run start-server ``` This will start the server with stdio transport, which allows it to communicate with MCP clients. ## API ### Tools The MCP server exposes the following tools: #### 1. `validate_pinescript` Validates PineScript code for syntax errors and warnings. **Parameters:** - `script` (string): The PineScript code to validate - `version` (string, optional): Expected PineScript version (e.g., 'v5', 'v4') **Returns:** - `valid` (boolean): Whether the script is valid - `errors` (string[]): List of syntax errors - `warnings` (string[]): List of warnings #### 2. `fix_pinescript_errors` Automatically fixes common syntax errors in PineScript code. **Parameters:** - `script` (string): The PineScript code to fix **Returns:** - `fixed` (boolean): Whether any fixes were applied - `fixedCode` (string): The fixed script - `changes` (string[]): List of changes made #### 3. `get_pinescript_template` Provides validated templates for common PineScript strategies and indicators. **Parameters:** - `template_type` (string): Type of template ('strategy' or 'indicator') - `name` (string): Template name **Returns:** - `template` (string): The template code - `message` (string): Confirmation message ## Supported PineScript Features ### Syntax Validation The validator currently checks for: - Empty scripts - Version annotations - Balanced parentheses - String quotes - Comma placement in function calls - Deprecated functions in PineScript v5 - Incorrect variable export syntax ### Error Fixing The fixer can automatically fix: - Missing version annotations - Unbalanced parentheses - Unclosed string literals - Missing commas in function calls - Deprecated study() function - Incorrect variable export syntax ## Development ### Running Tests ```bash npm test ``` ### Debugging To run the server in development mode with automatic reloading: ```bash npm run dev ``` ## License ISC ## Contributing Contributions are welcome!
