What is the SQL Syntax Validator MCP Server?
AI Agents are great at writing SQL, but terrible reviewers. They often forget commas, close parentheses poorly, or use duplicated aliases in giant JOIN queries. Executing flawed queries directly on a production database can cause severe bottlenecks or deadlocks. This MCP solves this by validating the query local.
The Superpowers
- AST Parsing: Uses
node-sql-parserto evaluate the Abstract Syntax Tree. It tells the AI exactly where the syntax error is located before it touches the database. - Dialect Support: Supports MySQL, PostgreSQL, MariaDB, and BigQuery syntax.
Built-in capabilities (1)
Pass the raw SQL string and optionally the dialect (mysql, postgresql, mariadb, bigquery). The engine checks for syntax errors offline, preventing runtime crashes. Validates an SQL query by parsing its Abstract Syntax Tree (AST) offline before execution
Why Cursor?
Cursor's Agent mode turns SQL Syntax Validator into an in-editor superpower. Ask Cursor to generate code using live data from SQL Syntax Validator and it fetches, processes, and writes. all in a single agentic loop. 1 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Every tool call from Cursor to the SQL Syntax Validator MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Does it connect to my database?
No, it purely evaluates the string syntax local.
Can it prevent SQL Injection?
It ensures the syntax is structurally valid, but does not analyze business logic intent.
What SQL dialects are supported?
MySQL, PostgreSQL, MariaDB, and BigQuery.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
Server shows as disconnected
Check Settings → Features → MCP and verify the server status. Try clicking the refresh button.
