01 · Install ARC 1

Claude Code

claude mcp add arc-mcp-arc-1 -- npx -y arc-1

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "arc-mcp-arc-1": {
      "command": "npx",
      "args": [
        "-y",
        "arc-1"
      ]
    }
  }
}

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

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 · container (OCI image) - can be sandboxed away from your filesystem

license MIT - declared in the repository

npm package arc-1 - unscoped; check the name against the project README before installing

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

SAPRead

Sapsearch

1 tool - e.g. Object search + full-text source code search across the system

1 tool - e.g. Create/update/delete ABAP source and DDIC metadata with automatic lock/unlock (PROG, CLAS, INTF, FUNC, FUGR, INCL, DDLS, DCLS, DDLX, BDEF, SRVD, SRVB, SKTD/KTD,

SAPWrite

Sapactivate

1 tool - e.g. Activate ABAP objects - single or batch (essential for RAP stacks), with guarded retry for the S/4HANA ED064 batch quirk. Publish/unpublish OData service bindin
