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"]
    }
  }
}

Usage with Google Antigravity

Add to ~/.gemini/antigravity/mcp_config.json:

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

Or use the public HTTP server (no install):

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

Version Pinning

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

{
  "mcpServers": {
    "pinescript-docs": {
      "command": "uvx",
      "args": ["pinescript-mcp==0.6.9"]
    }
  }
}

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

Alternative: pip install

If you prefer pip over uvx:

pip install pinescript-mcp==0.6.9

Note: "command": "pinescript-mcp" only works if the install location is in your PATH. The uvx method above is more reliable as it handles environments automatically.

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 (10)

Tool	Description
get_manifest()	Start here for natural language questions — routing guide
resolve_topic(query)	Fast lookup for exact API terms (ta.rsi, repainting)
search_docs(query)	Grep for exact strings across all docs
list_docs()	List all documentation files with descriptions

Available Prompts

Prompt	Description
debug_error(error, code)	Analyze a Pine Script compilation error
convert_v5_to_v6(code)	Convert Pine Script v5 code to v6 syntax
explain_function(name)	Explain a Pine Script function in detail

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

Lint Rules (17 total)

The lint_script tool checks for common Pine Script issues without using AI:

Rule	Type	Description
S000	Warning	AST parser failed (graceful fallback)
S001	Error	Real syntax errors (via pynescript AST parser)
E001	Error	input.enum() with const string constants
E003	Error	Return type keyword on function declaration
E005	Error	study() → use indicator()
E006	Error	security() → use request.security()
E007	Error	alertcondition() in strategy scripts
E009	Error	format.currency doesn't exist
E010	Error	Direct na comparison (use na() function)
E012	Error	Unknown/hallucinated function
E013	Error	input.enum() with options array
E014	Error	strategy() missing title parameter
E015	Error	Mismatched string quotes
W001	Warning	Missing //@version=6
W003	Warning	lookahead_on without justification
W004	Warning	High max_bars_back value
W005	Warning	Potentially unused variable

Performance

The HTTP server (Fly.io) uses response caching with 1-hour TTL for documentation lookups, making repeated queries very fast.
