## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1247 tokens (~95/item across 13 items; 13 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 1/100
  - Stability check failed: schema churn in the 3 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 68, −1)

- [security regression] Stability: 0.07 → fail
- [security regression] A breaking change shipped without a version bump: still 1.0.0
- [security regression] Tool “get_player_metrics” was removed
- [functional] New tool “get_entity_metrics”

### 2026-08-02 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-01 (score 68, +5)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-31 (score 63)

First indexed and scored.

## MCP tools (13)

### `get_current_insights` (~59 tokens)

Muffed's current reads

Muffed's published editorial reads on what is real in the NFL right now — each one a dated, sourced claim with its supporting figures, from the /trends board.

Input parameters:

- `limit` (integer)
- `subject` (string)

### `query_stat_leaders` (~92 tokens)

Verified stat leaders

Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Call list_metrics for the metric keys this accepts.

Input parameters:

- `entity_kind` (string)
- `limit` (integer)
- `metric` (string, required)
- `order` (string)
- `position` (string)
- `season` (integer)

### `get_entity_metrics` (~99 tokens)

A player's or team's verified figures

Every verified figure Muffed holds for one NFL player or one NFL team (by name or abbreviation, e.g. "Bijan Robinson" or "DEN"), with the source's rank where one exists. Names are resolved before lookup; an unrecognised name returns the closest matches rather than a guess.

Input parameters:

- `entity` (string, required)
- `entity_kind` (string)
- `metric` (string)
- `season` (integer)

### `compare_entities` (~84 tokens)

Compare two players or teams

Two players or two teams shown side by side on the verified metrics both have, with each side's source rank. States both figures and stops: it names no winner, no margin and no recommendation.

Input parameters:

- `a` (string, required)
- `b` (string, required)
- `entity_kind` (string)
- `metrics` (array)
- `season` (integer)

### `get_metric_definition` (~63 tokens)

What a metric means

What a verified metric measures, which seasons it actually covers, how it is ranked, its licence and its attribution. Season coverage is often narrower than a decade — rushing yards over expectation, for instance, exists from 2018 onward.

Input parameters:

- `metric` (string, required)

### `list_metrics` (~65 tokens)

List verified metrics

The metric keys Muffed can answer on, with their labels and the seasons each one covers. Returns keys and coverage only, never figures.

Input parameters:

- `entity_kind` (string)
- `limit` (integer)
- `search` (string)
- `season` (integer)

### `verify_claim` (~58 tokens)

Check a stated figure against Muffed

Checks structured claims against Muffed's verified panel. Each claim comes back confirmed, wrong (with the actual value), or unverifiable (with the metric's real season coverage). Takes structured fields only, not sentences.

Input parameters:

- `claims` (array, required)

### `get_backfield` (~57 tokens)

A team's backfield

Muffed's published handcuff page for one team's backfield, plus the current depth chart and injury status from Sleeper. Answers who backs up a starter, and who replaces one who is out.

Input parameters:

- `team` (string, required)

### `sleeper_find_leagues` (~57 tokens)

Find a Sleeper user's leagues

Lists the NFL leagues a Sleeper username belongs to, so a league id can be picked for the other league tools. Muffed stores nothing about who called it.

Input parameters:

- `season` (string)
- `username` (string, required)

### `sleeper_get_league` (~52 tokens)

A Sleeper league's setup

One league's name, season, size, current week, detected scoring format, and the manager-to-roster map. Everything downstream reads better once this has been called.

Input parameters:

- `league_id` (string, required)

### `sleeper_matchup_preview` (~71 tokens)

Verified context for a matchup

Both sides of a league matchup, with the verified figures Muffed holds for the players involved and each team's record. Muffed does not project outcomes, name a winner, or recommend a lineup.

Input parameters:

- `league_id` (string, required)
- `team` (string, required)
- `week` (integer)

### `sleeper_roster_stories` (~57 tokens)

A roster's verified stories

One team's roster mapped to the verified figures and published Muffed surfaces for each player. Players Muffed does not cover are listed as uncovered rather than omitted.

Input parameters:

- `league_id` (string, required)
- `team` (string, required)

### `sleeper_standings_story` (~56 tokens)

A league's standings

League standings derived from Sleeper's roster settings — records, points for, and points against where available. Sleeper publishes no standings endpoint, so these are computed from the roster rows.

Input parameters:

- `league_id` (string, required)
