## 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 2026-08-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it.
  - 2 of 30 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 3 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 358 tokens (~119/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (3)

### `delegate` (~313 tokens)

Offload a self-contained subtask to a cheaper model and return its output.

WHEN TO USE: hand off *replaceable grunt work* to save your premium tokens —
boilerplate code, small bug fixes, formatting, translation, reading/summarizing
long documents, drafting routine copy. Do NOT delegate judgment work (planning,
architecture, final review, talking to the user) — keep that for yourself.

The delegated model sees ONLY the `task` string and has NO access to this
conversation. So make `task` fully self-contained (include all needed context).

Args:
    task: Complete, self-contained instruction for the cheap model.
    model: "auto" (default) routes by task — code→deepseek, long docs→kimi,
           Chinese→qwen, multi-step→mimo, quick chores→flash. Or force an
           alias (deepseek/mimo/flash/kimi/qwen) or a raw proxy model_name.
    max_tokens: Output cap. Default 4000 (kept large so reasoning models that
           spend budget on hidden thinking still return non-empty text).

Note: a call typically takes ~10-60s (longer for big inputs) and blocks until
the cheap model returns, so prefer one focused task per call.

Returns:
    The model's text output, or a string starting with "[delegate-error]" on failure.

Input parameters:

- `max_tokens` (integer)
- `model` (string)
- `task` (string, required)

Output parameters:

- `result` (string)

### `savings` (~24 tokens)

Show what delegating has kept off your premium quota (estimates, list prices).

Output parameters:

- `result` (string)

### `list_models` (~21 tokens)

List the model aliases available to delegate(), with their best use.

Output parameters:

- `result` (string)
