// DEPLOYMENT CONFIG VALIDATION

MSI CONFIG
VALIDATOR.

MCV validates deployment Config XML files against the PRM MSI XSD schema — the same schema used by the original C# ConfigFileManager tool. Paste your XML, click Validate, and get line-numbered errors, schema warnings, and a parsed summary of all Jira tickets and deployment files referenced in the document. No account required.

// VALIDATION

Paste, Validate, Fix

The tool is a single two-panel screen. Paste your Config XML into the left textarea. Click Validate XML or press Ctrl+Enter. The right panel shows the validation result banner (green for valid, red for invalid), any line-numbered errors, schema warnings, and the parsed summary of all Deployment elements. No page reload — results appear instantly via the JSON API.

Line-Numbered Error Detail

When validation fails, every schema error is reported with the exact line number and a human-readable message from the XSD validator. Schema warnings (non-fatal) appear separately below errors. The parsed summary still runs even on invalid documents so you can see what was successfully parsed before the error occurred.

// FEATURES

Built for the PRM Schema

Embedded XSD Schema
The PRM MSI schema is compiled once on first request and cached. No external schema files to manage or keep in sync.
No Data Stored
Validation is entirely stateless. Your XML is parsed in memory and the result is returned. Nothing is written to a database.
Parsed Summary
Even on invalid documents, MCV parses all Jira and File elements it can find and shows them in a table with all attributes.
Ctrl+Enter Shortcut
Keyboard-first workflow. Press Ctrl+Enter while in the textarea to run validation instantly without reaching for the mouse.
MCP Exposure
The validation endpoint is exposed as the mcv_validate_xml MCP tool. Callable from any MCP-aware client without a browser.
No Account Required
MCV is a public WebTool. Open it, paste your XML, and validate. No login, no signup, no tracking.
