Mcp Server Sfmc
If you write AMPscript, SSJS, or GTL for Salesforce Marketing Cloud, this gives your AI assistant validation, function lookup, and diff-aware PR review through MCP tools. It bundles the same language engine that powers the SFMC Language Service VS Code extension, so you get syntax checks, arity validation, and fix suggestions for all three languages plus HTML with embedded blocks. The review_change tool is built for CI: it only flags issues in added lines and maps diagnostics back to diff line numbers. You also get searchable excerpts from mirrored Salesforce Help covering Marketing Cloud Engagement setup and operations, with explicit scoping to avoid confusion with Marketing Cloud Next. Works with Cursor, Claude Desktop, Windsurf, and VS Code via stdio transport.

mcp-server-sfmc
MCP server providing Salesforce Marketing Cloud language intelligence — AMPscript, SSJS, GTL, and Marketing Cloud Next (MCN) Handlebars — as Model Context Protocol tools, resources, and prompts for AI-assisted development and code review. Ships two searchable doc indexes: MCE help (Salesforce Help for Marketing Cloud Engagement administration and setup) and MCN developer docs (Marketing Cloud Next REST API and developer reference). Includes full Marketing Cloud Next (MCN) platform awareness: auto-detects whether a project targets MCE or MCN, restricts completions and validation to MCN-supported functions, flags SSJS as unsupported in MCN, surfaces MCN behavioral differences in hover and diagnostics, validates MCN Handlebars templates, and provides a migration toolkit to analyze and rewrite code for MCN — including AMPscript ↔ Handlebars and SSJS → Handlebars conversion.
Built on sfmc-language-lsp, the same engine that powers the SFMC Language Service VS Code extension.
