Audits Pine Script v6 strategies via static analysis, detecting traps that compile but cause backtest-vs-live divergence such as fill-timing issues, ATR-smoothing mismatches, lookahead bias, VWAP-anchoring drift, exit-drift, and v6 syntax footguns.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@pinescript-audit-mcp audit this Pine Script v6 strategy for lookahead bias and fill-timing traps"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server that statically audits Pine Script v6 strategies for the specific traps that compile clean, backtest beautifully, and then diverge from live behavior.
Pine Script strategies can compile with zero errors and still behave differently live than in the backtester — fill-timing assumptions, ATR-smoothing mismatches, lookahead bias, VWAP-anchoring drift, and exit-drift are all silent, syntactically valid patterns that the compiler has no reason to flag. This catches them before they cost real money finding out live.

Fill-timing traps — orders that backtest as filling at a price/bar the live broker can't actually match
ATR-smoothing mismatches — RMA vs. SMA vs. EMA smoothing assumptions that quietly change signal timing
Lookahead bias — request.security() and similar calls that leak future bar data into historical evaluation
VWAP-anchoring drift — anchor-period assumptions that behave differently on session boundaries live vs. in backtest
Exit-drift — exit logic that behaves differently depending on calc_on_every_tick and bar-close assumptions
Pine v6 syntax traps — v6-specific footguns that compile but change behavior from v5 equivalents
audit_pine_strategyRuns the full static-analysis pass against a submitted Pine Script v6 strategy and returns every trap found, with the specific line and a plain-English explanation of the backtest-vs-live divergence it causes.
