Pine Script v6 Documentation

paulieb89/pinescript-mcp

Connects Claude and other MCP clients to Pine Script v6 documentation with lookup, validation, and linting tools. You get exact function checks (like whether ta.supertrend exists), doc searches across concepts like repainting and execution models, and prompts for debugging errors or converting v5 code. Built for traders and quants writing TradingView strategies who need AI to stop hallucinating deprecated syntax or inventing functions. Runs over stdio locally via uvx or hits a hosted endpoint at pinescript-mcp.fly.dev for zero setup. Documentation is bundled and versioned, so pinning to a release keeps your agent behavior consistent. Includes the full v6 reference plus style guides and common gotchas.
