How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
get_registry Get a governed registry's contents ~108
Returns the raw, current contents of a governed registry — the live source of truth for which colors/sub-layer types a diagram IR may use. This is governed vocabulary, not the IR's structural document contract; see get_schema for that. For 'colors' specifically, pass family to get just one color family instead of the whole registry.
| Name | Type | Req | Description |
|---|---|---|---|
| family | string | – | For the 'colors' registry only: restrict to a single family, e.g. 'standard'. |
| name | string | yes | – |
No output schema declared.
No examples provided.
get_schema Get the diagram IR JSON Schema ~51
Returns the ArchSmith diagram IR JSON Schema (draft 2020-12) — the structural contract a diagram IR document must satisfy. Call this, and get_registry for governed vocabulary, before authoring an IR.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_registries List governed registry names ~32
Lists the governed registries (e.g. sub-layers, colors, icons) available via get_registry.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
render Render a diagram IR to SVG ~237
Validates then renders an ArchSmith diagram IR to a complete SVG document. Call get_schema and get_registry first to learn the required IR structure and governed vocabulary before authoring a document. Font embedding defaults to false to keep MCP responses compact; only opt in if the SVG must render portably without installed fonts — embedding adds a font subset sized to this diagram's own text, not a fixed cost, but it's still an added cost worth opting into deliberately. A render under 25,000 bytes is returned as one text content block; a larger one (e.g. a big diagram, or embedFonts:true on one) is returned as a resource_link instead, fetchable via resources/read, so the tool result itself never grows unbounded. Fails with the validation errors (isError: true) instead of rendering if the IR is invalid — never renders broken geometry from an invalid document.
| Name | Type | Req | Description |
|---|---|---|---|
| embedFonts | boolean | – | Embed the bundled Arimo font for portable rendering, subset to just the glyphs this diagram's text needs (not the whole font). Default: false. |
| ir | object | yes | The diagram IR document to render. |
No output schema declared.
No examples provided.
validate Validate a diagram IR ~70
Validates an ArchSmith diagram IR document against the schema and governed registries (sub-layers, colors). Call get_schema and get_registry first to learn the required structure and governed vocabulary before authoring an IR. Returns { valid, errors }.
| Name | Type | Req | Description |
|---|---|---|---|
| ir | object | yes | The diagram IR document to validate. |
No output schema declared.
No examples provided.

What is the ArchSmith MCP server?
ArchSmith is an MCP server listed in the public MCP registry as io.github.ayeshLK/archsmith. Render and validate ArchSmith architecture diagrams from a governed JSON IR. This page covers its npm package (@archsmith/mcp-server).
Is the ArchSmith MCP server safe to use?
ArchSmith scores 73 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 24 October 2026. It declares no install or post-install scripts. 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 ArchSmith MCP server expose?
ArchSmith exposes 5 tools: get_schema, validate, render, list_registries, get_registry. Their descriptions and schemas cost roughly 498 tokens of context every time the server is loaded.
Is the ArchSmith MCP server still maintained?
ArchSmith is still listed as active in the MCP registry. We last reached this channel on 24 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
