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 Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 743 tokens (~123/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 Coverage82
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 45% 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

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 →
check_cells_available Check cells and prices ~104
Price a selection of cells right now and say whether it can be ordered (meets the minimum, not reserved, not in image review). Nothing is reserved or charged. Wraps POST /api/quote. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
| Name | Type | Req | Description |
|---|---|---|---|
| areas | array | yes | One to 20 non-overlapping areas; colours are optional here. |
No output schema declared.
No examples provided.
create_order Create an order (returns USDC payment details) ~234
Create an order for cells and return the USDC payment details (recipient wallet, token, amount_units, Solana reference, pay_by, status URL). This tool does not pay: the caller sends the USDC transfer itself before pay_by. Same validation and limits as the website (minimum cells, at most 16 colours (image orders are not supported here), rate limits, unpaid orders per IP). accepted_terms must be true and means you accept the terms at https://cellionaire.com/terms. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
| Name | Type | Req | Description |
|---|---|---|---|
| accepted_terms | boolean | yes | Must be true: you accept the terms (https://cellionaire.com/terms). |
| areas | array | yes | One to 20 non-overlapping areas, each a rect + color and/or a list of cells with colours. |
| network | string | yes | USDC network you will pay on. |
| owner | string | – | Public display name shown on the cells (max 40 characters). Default "anonymous". |
No output schema declared.
No examples provided.
get_order_status Order status ~71
Status of an order and its USDC payment (state, received, remaining, confirmations, refunds). Wraps GET /api/order/{id}. status: pending, processing, paid, pending_review, expired, cancelled, late_paid, refund_pending, refunded, failed.

read_region Read a rectangle of the wall ~137
Pixels and owners of a rectangle (w*h <= 10000). format "json" (default): base64 RGBA pixels plus runs of empty / buyer (with public display name) / house cells. format "png": the rectangle as a PNG image. Wraps GET /api/region. Wall coordinates: x 0..999 (left to right), y 0..999 (top to bottom); cell index = y*1000 + x.
