Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1173 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name cellionaire.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1173 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1173 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    8 of 14 parameters have a description (57%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-04T19:12:10.105841Z, within 180 days.

Capabilities

Tools 7

check_cells_available

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.

Discovered
create_order

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. If you can pay with x402, use prepare_x402_order instead (one request, no transfer to build). If you have no wallet, give status_url to a human.

Discovered
get_order_status

Status of an order and its USDC payment (state, received, confirmations, refunds). usdc.remaining is an amount to send only when usdc.can_topup is true, or when state is waiting (then it is the one full amount). If can_topup is false after a payment was seen, remaining is omitted: do not send a second transfer. Wraps GET /api/order/{id}. status: pending, processing, paid, pending_review, expired, cancelled, late_paid, refund_pending, refunded, failed.

Discovered
get_wall_info

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

Discovered
prepare_x402_order

Price cells and return a ready-to-send x402 request (URL, method, headers, JSON body, exact amount). Nothing is reserved or charged. Send it with an x402 client (x402-fetch, x402-axios, @x402/fetch); it pays and creates the order in one request. Raise the client's max amount if the price is above its default cap (x402-fetch 0.10 USDC, @x402/fetch 1 USDC). Cells that already have an owner can be bought over at the overwrite price (get_wall_info prices.rule: the multiplier times the last price while the cell is inside its reset window, otherwise the empty-cell price); total_usd here, and the 402 of the returned request, state the exact amount. Areas map to the HTTP body as [y*1000+x, 0xRRGGBB] pairs.

Discovered
read_region

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.

Discovered
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.
