## 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)

Scored 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.

  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 114 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 246 tokens (~82/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (3)

### `metamodel_list_projects` (~35 tokens)

Browse available MetaModel calculators and engineering models. Returns project names, descriptions, tokens, and model names for each published project.

### `metamodel_get_schema` (~68 tokens)

Get the input/output schema for a published MetaModel project. Returns model names, input parameters (with types, defaults, validation), and output fields. Use a token from metamodel_list_projects.

Input parameters:

- `token` (string, required): The publish token of the project (from metamodel_list_projects)

### `metamodel_compute` (~143 tokens)

Run a computation on a MetaModel project. Send input values and get computed outputs from all models. Inputs are auto-routed to the correct model by property name. Optionally specify a single model to target. Use metamodel_get_schema first to discover available inputs and outputs.

Input parameters:

- `inputs` (object): Input values as key-value pairs (e.g., {"width": 12, "height": 8}). Auto-routed to the correct model. Omitted inputs use defaults.
- `model` (string): Target a specific model by name. When omitted, returns outputs from ALL models (recommended).
- `token` (string, required): The publish token of the project
