Common questions
Is MCP Server Sfmc safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (2.10.1) reached the registry 24 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

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.
Shared-diagnostic migration
sfmc-language-lsp 4.0.0 changes shared validator codes to canonical sfmc/... IDs and preserves quick-fix variants and original payloads in a namespaced envelope. See the LSP migration and rule documentation. Documentation URLs are owned by the LSP version, not this MCP package.
Consumer regression coverage checks the canonical SSJS diagnostics, distinct polyfill/replacement payloads, and overlap suppression. This is not a new MCP tool or a promise that every tool response exposes raw LSP diagnostics.
Version 2.10.0 adopts ampscript-data: ^4.2.0 and sfmc-language-lsp: ^4.2.0 from npm. This Winter ’27 (API 68) catalog update makes the current AMPscript and shared language-service metadata available to MCP clients. MCP validation and review output continues to format locations, severities, and messages rather than expose raw LSP codes or envelopes.
VS Code MCP Server Gallery (@mcp)
This package is registered with the official MCP Registry as `io.github.JoernBerkefeld/mcp-server-sfmc` so it can appear in Visual Studio Code when you use the `@mcp` filter in the Extensions view (see the publish quickstart). Enable `chat.mcp.gallery.enabled` if the gallery does not show.
The registry only stores metadata; the server still runs locally via stdio (for example npx -y mcp-server-sfmc@latest). This is separate from `@contribute:mcp`, which lists VS Code extensions that contribute MCP definitions — use the SFMC Language Service for that path.
After publishing metadata (see Publish an MCP Server or the release workflow), you can confirm the entry with:
curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.JoernBerkefeld/mcp-server-sfmc"
VS Code without manual MCP config
If you use the SFMC Language Service extension (1.101+), it registers this MCP server for discovery in VS Code — you normally do not need to edit .vscode/mcp.json or run npm install for that path; VS Code still launches the published package via npx when the server starts.
For other editors, or if you prefer explicit configuration, use the npx or install options below.
Using this package without the VS Code extension
You do not have to install the VS Code extension. Pick one way to run the server:
| Approach | When to use it | |
|---|---|---|
| `npx` (no install) | Default in the examples below. Runs the latest published version from npm on demand; first run may download the package. Requires Node.js and npm (which provides npx). | |
| `npm install -g mcp-server-sfmc` | Same CLI as npx, but the package stays on disk so startup is faster and you can set "command": "mcp-server-sfmc" with empty args in your MCP config. | |
| `npm install mcp-server-sfmc` in a project | Keeps a pinned version in that folder's node_modules — point your MCP config at npx mcp-server-sfmc with cwd set to the project, or run ./node_modules/.bin/mcp-server-sfmc directly. | |
| `sfmc-review-diff` (bundled CLI) | For CI: spawns this MCP server, calls review_change on a unified diff (stdin or file), exits non-zero on ERROR by default. Install the package in the job, then e.g. `git diff base...HEAD \ | npx sfmc-review-diff`. |
None of these replace the VS Code extension for editing (syntax, LSP, snippets); they only expose the MCP server to tools that speak the Model Context Protocol.
CI templates and sfmc-review-diff
Ready-to-copy workflows (GitHub Actions, GitLab CI, Jenkins, Azure Pipelines, Bitbucket Pipelines) live under [`ci-templates/`](./ci-templates/). They run `eslint-plugin-sfmc` on changed files and `sfmc-review-diff` on the PR/MR unified diff. See [`ci-templates/README.md`](./ci-templates/README.md) for what each file does and how the two checks differ.
What it gives your AI assistant
| Feature | Details |
|---|---|
| Validation | Syntax errors, unknown functions, arity mismatches, unsupported SSJS syntax; target: 'next' flags MCN-incompatible functions and all SSJS; validate_handlebars checks MCN Handlebars helper names, arity, block balance, and unsupported constructs |
| Lookup | Full function signatures, parameters, return types, MCN compatibility badge (API version), behavioral notes, and examples |
| PR review | Diff-aware review tool that surfaces issues in the exact lines that changed |
| Fix suggestions | Concrete, compilable replacement code; target: 'next' includes MCN platform issues |
| Completions | AMPscript completions (filtered to MCN-supported when target: 'next'); SSJS catalog (redirects to AMPscript for MCN) |
| Platform detection | detect_sfmc_platform checks .mcdevrc.json (MCE) or sfdx-project.json (MCN) in the project root |
| MCN compatibility analysis | check_mcn_compatibility analyzes files for MCN readiness — per-function classification (supported / needs review / not supported), SSJS block migration difficulty, and an executive summary |
| MCN migration | rewrite_for_mcn (tool + prompt) deterministically rewrites AMPscript and converts convertible SSJS to AMPscript for MCN, then applies AI reasoning to remaining manual-rewrite sections |
| Code conversion | convertSsjsToAmpscript and convertAmpscriptToSsjs (tool + prompt hybrid) — rule-based conversion with AI-enhanced handling of flagged sections |
| MCN Handlebars | lookup_handlebars_helper, list_handlebars_helpers, get_handlebars_completions, and write_handlebars (authoring) backed by the handlebars-data catalog |
| Handlebars conversion | convertAmpscriptToHandlebars, convertHandlebarsToAmpscript, and convertSsjsToHandlebars (tool + prompt hybrid) — data-driven from ampscript-data handlebarsEquivalent / handlebarsExact |
| Prompts | Guided prompts for writing AMPscript/SSJS/Handlebars (with MCN constraints), reviewing code, converting between languages, and rewriting for MCN |
| Resources | Full function catalogs, keyword list, unsupported ES6+ syntax list, MCN Handlebars helper and binding catalogs |
| Help search | search_help (unified, auto-detects MCE vs MCN from project root); search_mce_help (MCE help, 7 product scopes); search_mcn_help (MCN developer API reference) |
Mixed HTML validation boundary
Starting with version 2.10.1, validate_sfmc_html validates embedded AMPscript/GTL and applies SSJS checks only to actual server JavaScript bodies (runat="server", excluding AMPscript script bodies). Browser scripts and non-JavaScript script data are not sent to the SSJS validator. Server diagnostics retain locations in the original HTML, and browser declarations, Core loads, or polyfills cannot suppress server warnings. HTML without server JavaScript does not receive an SSJS incompatibility error solely because target is 'next'.
This tool does not validate browser JavaScript or provide DOM/type diagnostics. The standalone validate_ssjs tool continues to validate raw SSJS with its existing target-platform behavior.
This boundary uses the published validateMixedDocumentSsjs API from sfmc-language-lsp 4.3.1 or newer. Version 2.10.1 raises the dependency floor to ^4.3.1; release verification uses a clean registry-only installation.
