This MCP server provides a suite of validation tools to ensure prompt templates are syntactically correct and secure. Use validate_syntax to check for balanced delimiters, audit_variables to find undeclared placeholders, analyze_composition to measure dynamic content density, and security_scan to detect potential injection vectors where variable names mimic system commands.

4 tools expose this connector's capabilities to your AI agent.

analyze_composition

Calculates the density of dynamic content compared to static text

security_scan

Detects if any variable names pose a risk of prompt injection

audit_variables

Compares variables found in the template against a list of allowed variables

validate_syntax

Checks if the template's variable delimiters are properly opened and closed

See how to talk to your AI agent using Prompt Template Variable Injector Checker.

Check if this template is valid: 'Hello {user_name}, welcome to {location}!' with declared variables ['user_name', 'location'].

The template is valid. All delimiters are balanced and all variables are correctly declared.

Is this template secure: 'Execute command {RUN_COMMAND} now'?

No, the variable `RUN_COMMAND` poses a security risk as it mimics a system command pattern.

What is the dynamic density of 'The weather in {city} is {temp}'?

The dynamic density ratio is 0.33.

You can use the `validate_syntax` tool to verify that all delimiters like braces or angle brackets are properly opened and closed.
