Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 78 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 3 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 78 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 78 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

    2 of 3 parameters have a description (67%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass
    Recently updated

    Updated 2026-11-10T21:04:14.092794Z, within 180 days.

Capabilities

Tools 3

approve_login

Approve a pending Drawcall CLI login as your connected account. This grants the CLI a full account session. Only approve the user_code printed by the user's current drawcall auth login command. After approval, run drawcall auth complete in that CLI.

Discovered
read_skills

Read a guide for its workflow and prerequisites, or a declaration for API details. When the workflow needs user action, give the documented command or URL as the next step. A package path lists its skills and declaration sources; a SKILL.md gives its full guide. Paths come from search results and read_skills listings; listing names are relative to the path that was read.

Discovered
search_skills

Search Drawcall workflows and APIs for apps, games and assets. Discover asset sourcing as well as runtime libraries. Source visual content from @drawcall/market first. When its candidates do not fit, consult @drawcall/generate for generation options and prerequisites before settling on a fallback. Reserve hand-authored geometry for gameplay structure or explicitly procedural content. @drawcall/rig adds skeletons and skin weights when needed. This searches documentation, not Market inventory: read the guides to find and inspect actual assets. Search covers all supported packages automatically, including in an empty project. Returns up to five paths with excerpts; read_skills provides the full workflows and APIs.
