What does the Pine Script syntax checker MCP tool do?

It checks submitted TradingView Pine Script for syntax errors and returns structured diagnostics. Each diagnostic contains a message plus a positive row and column position, while separate flags report timeout or system failure.

Does the MCP tool fix Pine Script errors automatically?

No. The tool never modifies the supplied source. An agent can explain the returned diagnostics, but you decide what to change and can submit the revised code for another check.

What input does pine-script-syntax-checker accept?

It accepts one required code string containing nonempty Pine Script source. The schema rejects extra fields and limits the code string to 10,000,000 characters.

Does a clean syntax result mean the strategy is safe to trade?

No. A clean syntax result only means the checker did not report a syntax error. Review logic, repainting, data assumptions, costs, and risk controls before any paper or live use.

Can AI predict stock prices with this MCP tool?

No. AI cannot predict stock prices with certainty, and this MCP tool does not promise future returns. It gives an agent bounded data or validation results that still require independent review, risk controls, and source checking.

Example prompt

Use Pineify to check this Pine Script and explain each syntax diagnostic without changing the code.

Direct answer

What pine-script-syntax-checker does

Use this TradingView Pine Script MCP tool when an agent needs a bounded syntax check before a person reviews or runs a script. The tool passes the supplied source to the checker and returns the result in structured MCP content.

The input is one nonempty code string with a maximum length of 10,000,000 characters. The response states whether syntax errors were found, lists each diagnostic with a positive row and column position, and separates timeout states from system errors.

A successful syntax check does not test strategy logic, repainting, order behavior, or trading results. It is one review step before you inspect the code in TradingView and test its behavior with suitable data and risk assumptions.

Contract

What the agent sends and receives

Inputs

One required code field containing the complete TradingView Pine Script source.
The code must contain at least one non-whitespace character.
The code string can contain up to 10,000,000 characters.

Structured output

hasError, a boolean that states whether the checker found syntax errors.
errors, an array of row, column, and message diagnostics.
isTimeout, a boolean that identifies a checker timeout.
isSystemError, a boolean that identifies a service or response failure.

Capabilities

Where this MCP tool fits

Read-only syntax checking

Checks the supplied Pine Script without changing, formatting, or replacing any part of the source.

Located diagnostics

Returns each syntax message with a positive row and column position so an agent can point to the relevant part of the submitted code.

Explicit failure states

Reports timeout and system-error states separately from syntax findings, which prevents an unavailable checker from being mistaken for clean code.

Structured MCP output

Provides the same result as structured content and JSON text for compatible MCP clients and agent workflows.

Agent workflow

A bounded call from question to review

1
Send the source
Give the agent the full Pine Script and ask it to call pine-script-syntax-checker with that code string.
2
Read the status
Check isTimeout and isSystemError first. If both are false, use hasError and the diagnostics array to review the syntax result.
3
Review and test
Fix any reported syntax issues in your working copy, run the checker again, then inspect the script inside TradingView for logic and chart behavior.

Prompt examples

Questions an agent can route to this tool

"Use Pineify to check this Pine Script and explain each syntax diagnostic without changing the code."

"Run pine-script-syntax-checker on this TradingView indicator, then list every message with its row and column."

"Check this Pine Script strategy for syntax errors. If the checker times out or returns a system error, say so instead of treating it as valid."

"Validate this Pine Script source through MCP, then separate syntax findings from any logic concerns you notice during review."

Operator notes

How I review the result

When I check a TradingView indicator before pasting it into the editor, I send the full source so the reported row and column positions match my working copy.

When I review a script for AAPL, NVDA, or SPY, I treat a clean syntax result only as permission to continue testing. It says nothing about signal quality or returns.

If I see isTimeout or isSystemError, I stop the syntax review and retry later. I do not interpret an empty errors array as a pass in either state.

Boundaries to keep in the prompt

The tool checks syntax only. It does not prove that an indicator or strategy behaves as intended.
The tool does not edit, repair, format, or generate Pine Script.
A clean result does not detect repainting, future-data use, order-model assumptions, or poor risk controls.
Timeout and system-error results are failed checks, even when the errors array is empty.
The result is code-validation information, not investment advice or a prediction of market returns.

Pineify MCP is an information and code-validation tool, not investment advice. It does not promise returns, place trades, or modify a portfolio. Review timestamps, source fields, code diagnostics, and risk assumptions before acting.
