What is the SQL Parser AST Engine MCP Server?
A security agent receives a SQL query from user input. Is it safe? Does it access unauthorized tables? Is there a DROP TABLE hiding inside a subquery? An AI scanning the text will miss edge cases that a real parser catches.
This MCP parses SQL into a complete Abstract Syntax Tree — every table, column, JOIN, WHERE clause, subquery, and function call becomes a structured, inspectable object. Then it can rebuild valid SQL from the AST.
The Superpowers
- SQL Injection Detection: Decompose any query to inspect for unauthorized operations, table access, and injection patterns.
- 15+ Dialects: MySQL, PostgreSQL, MariaDB, SQLite, BigQuery, Snowflake, Hive, TransactSQL, and more.
- Bidirectional: Parse SQL→AST and rebuild AST→SQL with full fidelity.
- Table & Column Extraction: List every table and column referenced in a query — essential for data governance.
Built-in capabilities (1)
This is essential for security agents checking for SQL injection, DevOps agents auditing query performance, or any workflow that needs to understand SQL without executing it. Supported dialects: MySQL, PostgreSQL, MariaDB, SQLite, BigQuery, Snowflake, Hive, FlinkSQL, Noql, TransactSQL. Parses SQL queries into an AST and extracts tables, columns, and WHERE clauses. Supports 15+ dialects (MySQL, PostgreSQL, BigQuery, Snowflake, etc.)

Frequently asked questions
Can this detect SQL injection attempts?
Yes. Parse the query into AST and inspect the node types. If user input resulted in unexpected DROP, DELETE, UNION, or subquery nodes, the injection is exposed structurally — no regex guessing.
Which SQL dialects are supported?
15+: MySQL, PostgreSQL, MariaDB, SQLite, BigQuery, Snowflake, Hive, TransactSQL, FLINKSQL, FlinkSQL, PostgresQL, and more.
Can I rebuild SQL from the AST?
Yes. Parse SQL→AST, modify the AST programmatically (add WHERE clauses, change table names), and rebuild valid SQL. Full round-trip support.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
