## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 308 tokens (~154/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.

  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (2)

### `designfit_validate` (~123 tokens)

Validate design fidelity

Validate a rendered front-end against its Figma design. Tag each built element with data-designfit-id="<figmaNodeId>", pass the design spec (geometry + tokens, from designfit_extract or relayed from Figma's MCP), the running URL, and the component map. Returns a fidelity score and a machine-actionable fix-list of token, geometry, and presence violations.

Input parameters:

- `componentMap` (array, required)
- `design` (object, required)
- `tolerances` (object)
- `url` (string, required)
- `viewport` (object, required)

### `designfit_extract` (~185 tokens)

Extract a design spec from Figma

Turn a Figma frame into the design spec designfit_validate expects. Give it a Figma link (https://www.figma.com/design/<fileKey>/...?node-id=...), or fileKey + nodeId, and it fetches the node via Figma's REST API using the FIGMA_TOKEN env var; or paste the raw GET /v1/files/:key/nodes response as `nodes` and nothing is fetched. Returns { design, componentMap, viewport }: add `url` and call designfit_validate. Deterministic. Hidden nodes are skipped; a frame made only of vectors is one leaf (an icon). `maxDepth` limits how deep to go.

Input parameters:

- `fileKey` (string)
- `maxDepth` (integer)
- `nodeId` (string)
- `nodes` (object)
- `url` (string)

## Common questions

### What is the designfit MCP server?

designfit is an MCP server listed in the public MCP registry as io.github.as9978/designfit. Validate AI-built front-ends against Figma by tokens and geometry, not pixels. This page covers its npm package (designfit).

### Is the designfit MCP server safe to use?

designfit scores 71 out of 100 on VerifyMCP. We recorded 1 known advisory against 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 designfit MCP server expose?

designfit exposes 2 tools: designfit_validate, designfit_extract. Their descriptions and schemas cost roughly 308 tokens of context every time the server is loaded.

### Is the designfit MCP server still maintained?

designfit 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.

### What licence is the designfit MCP server under?

designfit declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
