## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-24.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1123 tokens (~187/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 70/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 9% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `search_commanders` (~55 tokens)

Search Commander cards

Find Commander candidates by name. The existing autocomplete may include non-commander cards; only the primary field is validated as a legendary creature. Use the exact commander name for build_mana_base.

Input parameters:

- `query` (string, required)

### `build_mana_base` (~265 tokens)

Build a Commander mana base

Generate 30–42 lands for a Commander within a USD purchase budget, optionally with acceleration. Supply ownedLands to buy only missing copies, lockedLands to keep specific lands, or currentLands with maxChanges for a limited upgrade. The USD budget minimum remains $20; it is a spending cap, not a target. Returns card quantities, reasoning, prices, coverage, warnings, and shopping links. Preview only: no saved build, email, purchase, or cart modification. Shopping imports match by card name; printing and final prices may differ. Always show warnings rather than describing a deficient build as optimal.

Input parameters:

- `bracket` (integer)
- `budgetUsd` (number)
- `commanderName` (string, required)
- `currentLands` (array): Existing mana base for a limited upgrade; these copies count as owned.
- `excludedCards` (array)
- `includeAcceleration` (boolean)
- `landCount` (integer)
- `lockedLands` (array): Required lands to retain, including quantities. Must be legal and not excluded.
- `maxChanges` (integer): Maximum replaced land slots when currentLands is supplied.
- `ownedLands` (array): Land copies already owned; budget and cart charge only missing quantities.

Upgrade a Commander precon

Upgrade a Commander precon using preconworkshop. Input a full quantity-prefixed Commander decklist including the commander. Budget is USD.

Owned is a quantity-prefixed list; locked/excluded are newline-separated card names. Nothing is purchased or saved publicly. Show all warnings and let the player choose swaps. Bracket analysis is guidance, not certification.

Input parameters:

Owned is a quantity-prefixed list; locked/excluded are newline-separated card names. Nothing is purchased or saved publicly. Show all warnings and let the player choose swaps. Bracket analysis is guidance, not certification.
