Category Design and Media
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 Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 393 tokens (~131/item across 3 items; 3 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
- Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 67% of tool parameters carry a description.Partial
- Structured output schemas are declared (33% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (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.

- 28 Oct 26 0
- Tool “read_skills” rewrote its description, which is the text the model reads security
- Server version: 0.3.17 → 0.3.18 functional
- “read_skills” reworded the description of “path” cosmetic

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 →
approve_login Approve CLI login ~66
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.
| Name | Type | Req | Description |
|---|---|---|---|
| user_code | string | yes | – |
No output schema declared.
No examples provided.
read_skills Read skills ~108
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.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | A path from search or a listing, e.g. /@drawcall/physics/ |
No output schema declared.
No examples provided.
search_skills Search Drawcall guides and APIs ~159
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | What you want to implement or learn how to do |
| Name | Type | Req | Description |
|---|---|---|---|
| packages | array | yes | Every selected package, in selection order |
| results | array | yes | The five best, best first, at most one per document. Empty until every selected package is ready. |
No examples provided.
How do I install the Drawcall MCP server?
Drawcall is a hosted endpoint at https://mcp.drawcall.ai/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Drawcall MCP server?
Drawcall is an MCP server listed in the public MCP registry as io.github.drawcall-ai/drawcall. Discover Drawcall workflows for 3D apps and asset creation; read APIs and approve CLI logins. This page covers its hosted endpoint (https://mcp.drawcall.ai/).
Is the Drawcall MCP server safe to use?
Drawcall scores 80 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 Drawcall MCP server expose?
Drawcall exposes 3 tools: search_skills, read_skills, approve_login. Their descriptions and schemas cost roughly 333 tokens of context every time the server is loaded.
Does the Drawcall MCP server require authentication?
No. We connected to Drawcall without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Drawcall MCP server still maintained?
Drawcall 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.
