How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability68
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2269 tokens (~567/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management43
- Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

generate_bingo_cards Generate bingo cards ~781
Use this when the user wants printable bingo cards: a bingo card generator or bingo card maker for a holiday party, classroom, baby shower, team meeting, or any game with their own words or phrases, or classic number bingo (1-75) or UK 90-ball tickets. Makes 1-200 different cards (3x3, 4x4 or 5x5, free centre on or off) with each item spread evenly, optionally so that no two cards share a winning line. Returns card 1, balance and uniqueness numbers, and links to a cards PDF (1, 2, 4 or 6 per page, cut lines), a caller sheet PDF and a CSV. Does not add pictures, and does not draw items or check claims (use show_bingo_caller). Not for a single personal goals card (use generate_goal_bingo) or for prize or money games.

Pass the same items and the caller_args (mode, grid_size, free_space, card_count, seed, unique_lines) from generate_bingo_cards, plus everything called so far in order. Draws use secure randomness.
