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 Security74
- 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability58
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage70
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 9% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_mana_base Build a Commander mana base ~265
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.

|---|---|---|---|
| bracket | integer | – | – |
| budgetUsd | number | – | – |
| commanderName | string | yes | – |
| currentLands | array | – | Existing mana base for a limited upgrade; these copies count as owned. |

| 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. |
