Security review: not tested

Score = points from our five tests (install, handshake, maintenance, docs, license). Not a quality or security rating. Methodology

  • Docs10/15
  • License10/10

Tested npm scryfall-mcp-server 0.1.1 (MIT; no repository listed; last published 2025-02-26, so the maintenance score is 0). Stdio, 7 tools over the public Scryfall API for Magic: The Gathering cards, no key. Real calls: search_cards (44 goblins), get_card_by_name (Lightning Bolt) and get_rulings by Scryfall ID all answered; rulings came back as an empty list. Our first get_rulings call used an Oracle ID, which the tool description allows but the API rejected with not_found; it was rerun with the card's Scryfall ID. Server reports version 0.1.0. search_cards returns very large results (about 295k characters for 44 cards).
Tool-call test (2026-11-11, direct MCP stdio client, no LLM): pass. 3 of 3 calls passed against the public Scryfall API. Evidence: local test run, Nov 11, 2026.

Transport (tested 2026-11-11): stdio

Token cost (estimate): approx. 562 tokens, cl100k estimate (7 tools, measured 2026-11-11, version 0.1.1). This is an estimate from our testing of the tool names, descriptions and input schemas, counted with cl100k_base.

What we tested and what we didn't

Tested on 2026-11-11

  • Install from the registry
  • We connected with no credentials and asked for its tool list: it listed 7 tools (Method details: MCP initialize then tools/list)
  • Maintenance signals (last push, archived/deprecated status)
  • Docs (README length, install and config example)
  • License (OSI-approved or not)
  • Token cost (estimate)

Not tested

  • Security: not audited (no code review, no permission or data-flow analysis)
  • Real tasks (no functional task runs yet)
  • Behaviour with real credentials or a real account
  • Performance, rate limits or load
  • Correctness of results beyond the listed tasks

Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
