## Connection (mcpServers)

```json
{
  "mcpServers": {
    "drawcall": {
      "type": "http",
      "url": "https://mcp.drawcall.ai/"
    }
  }
}
```


## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 45
- drivers: +website +reachable +uptime-99% +updated-5d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 94/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 577 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 577 tokens to load them all
- tool set hash: 3f145b4895141024561249a6258eee0a
- tools last changed: 2026-10-15T15:58:33.691Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.drawcall-ai/drawcall.svg)](https://protogrid.dev/servers/io.github.drawcall-ai/drawcall)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-15 `read_skills` changed (description) **meaning changed**
  - before: Read one path of the skills tree: a package (its skills and import paths), a SKILL.md, a section, or a type declaration. Paths come from search results and from what read_skills returns; in a listing, names are relative to the path that was read.
  - after: 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 import paths; 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.
- 2026-10-15 `search_skills` changed (title, description, inputSchema, outputSchema) **meaning changed**
  - before: Search the skills (guides) and TypeScript API of the npm packages a project uses. Pass every dependency as name@version with the installed version from the lockfile; a bare name searches the latest. Returns the five best results as paths with an excerpt; read a path with read_skills before writing code against it.
  - after: 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.

## 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.
- `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 import paths; 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.
