01 · Install Server Sfmc

Claude Code

claude mcp add joernberkefeld-mcp-server-sfmc -- npx -y mcp-server-sfmc

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "joernberkefeld-mcp-server-sfmc": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-sfmc"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package mcp-server-sfmc - unscoped; check the name against the project README before installing

registry namespace io.github.JoernBerkefeld is GitHub-verified and matches the repo owner

03 · What Server Sfmc can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can list all AMPscript functions, optionally filtered by platform: 'next' to return only MCN-supported functions, generate fix suggestions for each diagnostic in a code snippet. target: 'next' includes MCN fixes, list valid completions at a given cursor position, and detect the target platform for a project - checks .mcdevrc.json (→ "engagement") or sfdx-project.json (→ "next").
