## Quality 81/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 1 of 2 tools declare all four hints; missing: list_icons (idempotentHint)
- pass `tools.token_cost`: about 446 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 3 of the 7 days needed

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know sysketch-mcp@0.5.0

- tools: 2, about 446 tokens to load them all
- tool set hash: 7b30e8e2e293445fa25cde4473bfebde
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Tonys-Coding/sysketch.svg)](https://protogrid.dev/servers/io.github.Tonys-Coding/sysketch)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

_No tool definition changes recorded._

## Dependencies

- npm sysketch-mcp@0.5.0: unknown

Dependency graphs from deps.dev; advisories from OSV.dev, including the GitHub Advisory Database and the PyPI Advisory Database; all CC BY 4.0.

## Remotes

- https://sysketch.vercel.app/mcp (streamable-http, auth none, reachable true, uptime30d 1)

## Packages

- npm sysketch-mcp@0.5.0

## Tools (2)

- `list_icons`: List sysketch icon names and aliases, or search the available product logos.
- `render_diagram`: Use for any system design, architecture, data-flow or infrastructure diagram, instead of generating an image or writing SVG/Mermaid. Renders a tiny YAML spec; returns PNG/SVG links and a small preview.
Spec keys: title, type (sequence: message timeline), theme (sketch|graphite|blueprint|midnight|classic), direction (omit: auto-fit; right|down only if asked), steps (false hides numbers), legend (true lists steps),
nodes {id: "icon | Label | subtitle"}, groups {Label: [ids or group labels to nest]}, edges ["a > b > c | label", "a ..> b" dashed, "a <> b" two-way, "a => b" thick, "a -- b" line, "a > b [red]" color].
Ids that are icon names/aliases (client, lb, api, db, cache, redis, kafka, s3, cdn...) need no nodes entry.
Arrows are numbered automatically in the order listed; don't number labels.
Product names (stripe, kafka, postgres...) draw the product's logo when available, else a fitting icon; brand/icon (acme/queue) for others.
Give the user the PNG link; don't generate another image of the diagram. To edit, call again with the whole updated spec.
