# SQL Static Query Analyzer MCP for AI Agents MCP

> SQL Static Query Analyzer MCP for finding dangerous SQL patterns before they hit your database. It scans queries for security risks like injection and performance killers like SELECT * or missing WHERE clauses, all without running a single line of code.

## Overview
- **Category:** developer-tools
- **Price:** Free
- **Endpoint:** https://edge.vinkius.com/vk_preview_0XEKjm5gcLW4rAgtMYMcKmh6fMbgRmmrqY3YPLwK/mcp
- **Tags:** sql, static-analysis, security, performance, database

## Description

Writing SQL is easy until a missing WHERE clause wipes out a production table or an unparameterized string opens a backdoor for hackers. This MCP lets your agent look at your queries and spot these mistakes while you are still in the IDE. It does not need access to your actual database, so there is no risk of accidental execution during the scan. You just point it at your code, and it flags things like inefficient SELECT * statements or dangerous DELETE commands. Since Vinkius manages this connection, you can use it across any compatible client without worrying about the underlying setup. It is basically a second pair of eyes for your database logic, catching the small stuff before it becomes a high-priority incident.

## Tools

### analyze_sql
Scans a SQL string to find security risks and performance anti-patterns. It returns findings with severity levels and line numbers.

## Prompt Examples

**Prompt:** 
```
Is this query safe? 'DELETE FROM orders;'
```

**Response:** 
```
| Severity | Message | Line |
| :--- | :--- | :--- |
| **CRITICAL** | DESTRUCTIVE: Missing WHERE clause | 1 |

This query is flagged because it will wipe the entire table.
```

**Prompt:** 
```
Check this for performance issues: 'SELECT * FROM users WHERE id = 5'
```

**Response:** 
```
I found one issue:

* **Inefficiency**: Using `SELECT *` can increase network overhead. You should list the specific columns you need instead.
```

**Prompt:** 
```
Does this code have any injection risks? 'query = "SELECT * FROM accounts WHERE name = ' + input + "'"'
```

**Response:** 
```
**Security Risk Detected**

* **Type**: SQL Injection
* **Detail**: Unparameterized value detected. Using string concatenation for queries allows attackers to manipulate your database logic.
```

## Capabilities

### Catch destructive queries
Identifies DELETE or UPDATE statements that are missing a WHERE clause.

### Spot performance drains
Flags the use of SELECT * which can waste network and database resources.

### Detect injection vulnerabilities
Finds unparameterized values in your strings that could lead to SQL injection.

### Audit SQL patterns
Scans your code for known anti-patterns and security risks automatically.

## Use Cases

### Preventing production wipes
A developer accidentally writes a DELETE without a filter, asks their agent to check it, and the tool flags it as destructive.

### Securing new features
When adding a new API endpoint, use the tool to ensure no unparameterized inputs are being passed into queries.

### Optimizing legacy code
Point your agent at an old repository to find all instances of SELECT * that need refactoring for better speed.

### Quick PR audits
During a pull request, have your agent scan the new SQL migrations for any obvious anti-patterns or security holes.

## Benefits

- Stop accidental data loss by catching DELETE statements without a WHERE clause.
- Improve database performance by identifying inefficient SELECT * usage.
- Secure your application by finding unparameterized values that lead to injection.
- Reduce manual code review time with automated pattern matching.
- Audit queries safely because no actual execution takes place during the scan.

## How It Works

The bottom line is you catch database errors before they ever reach production.

1. Connect the MCP to your preferred AI client via Vinkius.
2. Pass a SQL query string or a block of code to your agent.
3. Get a detailed report showing the exact line number and the specific risk found.

## Frequently Asked Questions

**How does SQL Static Query Analyzer prevent data loss?**
It identifies DELETE or UPDATE statements that lack a WHERE clause, flagging them as destructive before you run them.

**Can I use SQL Static Query Analyzer with Claude?**
Yes. You can connect this MCP to Claude, Cursor, or any other compatible client through the Vinkius platform.

**Does this MCP connect to my live database?**
No. It performs static analysis on the text of your queries without ever executing them against a real database.

**What kind of security risks does SQL Static Query Analyzer find?**
It specifically looks for unparameterized values and other patterns that could lead to SQL injection attacks.

**Will SQL Static Query Analyzer slow down my development?**
Not at all. It uses fast pattern matching to scan your queries almost instantly as you work.

**Does this tool execute SQL queries against my database?**
No, it performs static analysis by inspecting the text of the query strings using pattern matching without any database connection.

**What kind of vulnerabilities can `analyze_sql` detect?**
It detects SQL injection risks from unparameterized values, destructive operations like `DELETE` without a `WHERE` clause, and inefficient patterns like `SELECT *`.

**Can I use this with Cursor or Claude Desktop?**
Yes, you can connect this MCP server to any compatible client like Cursor, VS Code, Claude Desktop, and Windsurf via Vinkius Edge.
