pinescript-mcp

MCP server providing Pine Script v6 documentation for AI assistants (Claude, etc.).

Enables AI to:

• Look up Pine Script functions and validate syntax
• Access official documentation for indicators, strategies, and visuals
• Understand Pine Script concepts (execution model, repainting, etc.)
• Generate correct v6 code with proper function references

Quick Start (stdio)

Works with Claude Code, Claude Desktop, Gemini CLI, and any MCP client that supports stdio:

{
  "mcpServers": {
    "pinescript-docs": {
      "type": "stdio",
      "command": "uvx",
      "args": ["pinescript-mcp"]
    }
  }
}

Public Server (No Install Required)

No Python or uvx needed — connect directly to the hosted server.

Streamable HTTP — Claude Code, Claude Desktop, Cursor, Cline (standard mcpServers with type field):

{
  "mcpServers": {
    "pinescript-docs": {
      "type": "http",
      "url": "https://pinescript-mcp.fly.dev/mcp"
    }
  }
}

Windsurf — uses its own serverUrl shape (see Windsurf docs). Edit ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "pinescript-docs": {
      "serverUrl": "https://pinescript-mcp.fly.dev/mcp"
    }
  }
}

ChatGPT — no config file. In ChatGPT, go to Settings → Connectors → Create and paste https://pinescript-mcp.fly.dev/mcp into the Server URL field. Developer Mode must be enabled (see OpenAI Developer Mode guide).

Claude.ai — add via the web UI's MCP connector settings, not a JSON file.

SSE (legacy transport, kept for older clients):

{
  "mcpServers": {
    "pinescript-docs": {
      "type": "sse",
      "url": "https://pinescript-mcp.fly.dev/sse"
    }
  }
}

Streamable HTTP is preferred — SSE is being phased out across the MCP ecosystem.

Version Pinning

Documentation is bundled in the package — each version contains a frozen snapshot. For reproducible agent behaviour, pin to a specific version:

{
  "mcpServers": {
    "pinescript-docs": {
      "command": "uvx",
      "args": ["pinescript-mcp==0.7.0"]
    }
  }
}

Without pinning, uvx pinescript-mcp gets the latest version.

Note: versions before 0.7.0 included lint_script and edit_and_lint tools that were removed in 0.7.0 (docs-only server). Pinning to 0.6.x will give you those tools back, but the auth gate on lint_script was never completed on the hosted Fly instance, so they'll return auth errors on HTTP. Pin 0.7.0+ for the current, working tool surface.

• "How do I create a trailing stop in Pine Script?"
• "What's the difference between var and varip?"
• "Is ta.supertrend a valid function?"
• "How do I avoid repainting with request.security?"

Documentation Coverage

The server bundles comprehensive Pine Script v6 documentation:

• Concepts: Execution model, timeframes, colors, methods, objects, common errors
• Reference: Types, variables, constants, keywords, operators, annotations
• Functions: Technical analysis (ta.*), strategies, requests, drawings, collections
• Visuals: Plots, fills, shapes, tables, lines, boxes, backgrounds
• Writing Scripts: Style guide, debugging, optimization, limitations

Why Use This?

AI models often hallucinate Pine Script functions or use deprecated v5 syntax. This MCP server grounds the AI in actual v6 documentation, preventing:

• Made-up function names (e.g., ta.hull doesn't exist, use ta.hma)
• Deprecated syntax from v4/v5
• Incorrect parameter orders
• Missing required arguments
