## 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 2026-11-05.

- **Endpoint Security**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 67/100
  - AI-judged instruction clarity (good).
  - 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.
  - 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**: 82/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 45% 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.

First indexed and scored.

## MCP tools (6)

### `get_wall_info` (~39 tokens)

Wall rules and prices

Rules, prices, size, minimum order, payment networks, terms version and whether purchases are open. Numbers come from the live settings. No input.

### `wall_overview` (~61 tokens)

Wall overview

Current wall version, the URL of the full-wall PNG (1 pixel = 1 cell; alpha 0 empty, 255 bought, 254 site-owned house art) and how to read regions. Wraps GET /api/wall. No input.

### `read_region` (~137 tokens)

Read a rectangle of the wall

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.

Input parameters:

- `format` (string)
- `h` (integer, required)
- `w` (integer, required)
- `x` (integer, required)
- `y` (integer, required)

### `check_cells_available` (~104 tokens)

Check cells and prices

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.

Input parameters:

- `areas` (array, required): One to 20 non-overlapping areas; colours are optional here.

### `create_order` (~234 tokens)

Create an order (returns USDC payment details)

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.

Input parameters:

- `accepted_terms` (boolean, required): Must be true: you accept the terms (https://cellionaire.com/terms).
- `areas` (array, required): One to 20 non-overlapping areas, each a rect + color and/or a list of cells with colours.
- `network` (string, required): USDC network you will pay on.
- `owner` (string): Public display name shown on the cells (max 40 characters). Default "anonymous".

### `get_order_status` (~71 tokens)

Order status

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.

Input parameters:

- `order_id` (string, required)

## Common questions

### What is the Cellionaire MCP server?

Cellionaire is an MCP server listed in the public MCP registry as com.cellionaire/wall. Read the 1000x1000 Cellionaire pixel wall and create USDC orders for cells; you pay on-chain. This page covers its hosted endpoint (https://cellionaire.com/mcp).

### Is the Cellionaire MCP server safe to use?

Cellionaire scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Cellionaire MCP server expose?

Cellionaire exposes 6 tools: get_wall_info, wall_overview, read_region, check_cells_available, create_order, get_order_status. Their descriptions and schemas cost roughly 646 tokens of context every time the server is loaded.

### Does the Cellionaire MCP server require authentication?

No. We connected to Cellionaire without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Cellionaire MCP server still maintained?

Cellionaire is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
