Render templates with Handlebars Template Compiler

Stop relying on your agent to guess string replacements. The `compile_template` tool forces a strict compilation cycle that evaluates your logic against provided JSON. It handles loops and conditionals exactly how your production mailer does. You catch syntax errors before the email hits a human inbox.

Validate JSON payloads for Claude Desktop

Your agent often breaks when mapping complex data. This server forces a schema-first approach by binding your data directly through the `compile_template` interface. If the data structure doesn't match the template requirements, the compiler rejects it. You get clean, predictable output every single time.

Production-ready email testing

Stop the back-and-forth of sending test emails just to check for a typo. Use `compile_template` to verify the final HTML output instantly in your chat window. It treats the template as code, not text. This ensures your marketing emails render exactly as intended without hidden tag failures.
