pinescript-mcp 0.2.0

MCP server providing Pine Script v6 documentation for AI assistants

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

Usage with Claude Code

Add to .mcp.json in your project (recommended):

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

Usage with Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

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

Alternative: pip install

pip install pinescript-mcp

Then use "command": "pinescript-mcp" directly in the config.

Public Server (No Install Required)

Connect directly to the hosted server - no Python or uvx needed:

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

Available Tools

Tool	Description
list_docs()	List all documentation files with descriptions
get_doc(path)	Read a specific documentation file
search_docs(query)	Full-text search across all docs
get_functions(namespace)	List valid functions (ta, strategy, etc.)
validate_function(name)	Check if a function exists in Pine v6
resolve_topic(query)	Map a question to relevant docs
get_manifest()	Get routing guidance for topics

Example Queries

• "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
