PineMCP

PyPI Python ChromaDB MCP License: MIT Tests

Complete PineScript v6 reference documentation MCP server with 1751 entries covering all functions, variables, constants, types, keywords, operators, and annotations from the official TradingView PineScript v6 reference.

Quick Start | Tools | Configuration | Database | Development

---

One Command. Two Minutes. Fully Functional.

pip install pinemcp
pinemcp

That's it. On first run, the server auto-builds the ChromaDB vector store from shipped JSON data (takes 30-60 seconds for embedding model download + indexing). Subsequent runs start instantly.

What you get:

• 6 MCP tools for PineScript v6 docs lookup, code validation, and code generation
• 1751 entries indexed in a local ChromaDB vector store (100% offline)
• Sub-millisecond hot cache for priority lookups
• Remote TradingView compiler integration for pine_compile and pine_repair
• Works with Claude Desktop, Cursor, Windsurf, OpenCode, and any MCP client

What you need:

• Python 3.10+
• Any MCP-compatible AI client

Why PineMCP?

AI coding assistants hallucinate PineScript v6 syntax. PineScript v6 introduced breaking changes from v5 (typed na, removed transp, when parameter removal, bool casting changes, etc.) that models trained on older code get wrong.

PineMCP gives AI assistants authoritative, real-time access to the complete TradingView v6 reference:

• 100% coverage: 919/919 base entries from the live TradingView v6 reference
• Semantic search: Vector embeddings find relevant docs by meaning, not just keywords
• Remote compilation: pine_compile validates code against the real TradingView compiler
• v5 to v6 migration: pine_repair(mode="migrate") applies all known v5->v6 replacements
• Code generation: pine_scaffold generates validated indicator or strategy templates
• 100% local: No network calls at runtime (except optional compiler validation)

Tool Details

pine_lookup(name, kind?) Get complete documentation for a PineScript v6 symbol by exact name. Auto-detects function, variable, type, constant, keyword, or operator. Returns syntax, parameters, returns, remarks, examples, and see-also links.

pine_search(query, category?, namespace?, return_type?, has_examples?, current_line?, n_results?) Semantic search across the entire v6 reference. Supports category filtering, namespace filtering, return type matching, example-only mode, and context-aware function suggestions based on the current line being typed.

pine_browse(namespace, category?, style?) Enumerate every member of a namespace (e.g., ta, strategy, array). style="cheatsheet" produces a compact, box-drawn signature summary.

pine_compile(code?, file_path?, explain?) Compile PineScript v6 code via the remote TradingView compiler. Supports inline code, file paths, and explain=True for error-specific fix hints.

pine_repair(code, context, mode?) Fix compiler errors (mode="targeted") or migrate v5 code to v6 (mode="migrate"). Applies all known v5->v6 breaking change replacements, then recompiles to verify.

pine_scaffold(kind, name, description?, inputs?, overlay?, initial_capital?, commission_pct?, pyramiding?) Generate a validated PineScript v6 indicator or strategy template. Pre-wired with standard inputs, risk parameters, and plot functions.

MCP Client Configuration

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "pinescript-v6": {
      "command": "pinemcp",
      "transport": "stdio"
    }
  }
}

Cursor / Windsurf / OpenCode

Add to your project's .mcp.json or global MCP config:

{
  "mcpServers": {
    "pinescript-v6": {
      "command": "pinemcp",
      "transport": "stdio"
    }
  }
}

SSE (HTTP)

pinemcp --transport sse --port 8080

Connect to http://localhost:8080. Set MCP_API_KEY env var for auth.
