- Is muffed live?
- Yes — it answered the hub's last check (checked 37m ago). It answered 99% of checks over the last 30 days.
- Is muffed free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does muffed have?
- 15 tools: search_metrics, sleeper_find_leagues, sleeper_roster_stories, compare_entities, sleeper_standings_story, query_stat_leaders, verify_claim, run_stat_query, ….
- Is muffed safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
list_metrics reads open 18h ago
What Muffed can answer on. By default a summary of metric families with their counts and season coverage; with search or detail:true, individual metric keys. Returns keys and coverage only, never figures.

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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "limit": { "type": "integer", "maximum": 10, "minimum": 1 }, "subject": { "type": "string" } } }arguments 14 linessearch_metrics reads unknown 4h ago
The verified metrics that match a topic — e.g. 'screens', 'blitz', 'time to throw' — ranked by a text match over each metric's key, label, common names and board description. Up to 20 entries, each with its key, subject, season coverage and the board it belongs to. Keys and coverage only, never figures.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "query" ], "properties": { "query": { "type": "string", "maxLength": 64, "minLength": 1 }, "season": { "type": "integer", "maximum": 2026, "minimum": 2016 }, "subject": { "enum": [ "team", "player" ], "type": "string" } } }arguments 26 linessleeper_find_leagues reads unknown 4h ago
Lists the NFL leagues a Sleeper username belongs to, with each league's id. Muffed stores nothing about the requester.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "username" ], "properties": { "season": { "type": "string", "pattern": "^\\d{4}$" }, "username": { "type": "string", "maxLength": 64, "minLength": 1 } } }arguments 18 linessleeper_roster_stories reads unknown 18h ago
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "league_id", "team" ], "properties": { "team": { "type": "string", "maxLength": 64, "minLength": 1 }, "league_id": { "type": "string", "pattern": "^\\d{6,24}$" } } }arguments 19 linescompare_entities reads unknown 13h ago
Two players or two teams shown side by side — by default on the metrics that matter for their position, on named metrics when `metrics` is set, and on the full set with all:true. Each side carries its source rank. States both figures and stops: it names no winner, no margin and no recommendation. `metrics` takes verified panel metric keys ("qb_anya.any_a") or their plain-English names. A measure outside the verified panel, such as yards per attempt, is refused with the nearest panel metrics.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "a", "b" ], "properties": { "a": { "type": "string" }, "b": { "type": "string" }, "all": { "type": "boolean" }, "season": { "type": "integer", "maximum": 2026, "minimum": 2016 }, "metrics": { "type": "array", "items": { "type": "string" }, "maxItems": 25 }, "entity_kind": { "enum": [ "player", "team" ], "type": "string" } } }arguments 38 linessleeper_standings_story reads unknown 13h ago
League standings derived from Sleeper's roster settings — records, points for, and points against where available. Sleeper publishes no standings endpoint, so these are computed from the roster rows.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "league_id" ], "properties": { "league_id": { "type": "string", "pattern": "^\\d{6,24}$" } } }arguments 13 linesquery_stat_leaders reads unknown 7h ago
Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Takes a verified panel metric key.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "metric" ], "properties": { "limit": { "type": "integer", "maximum": 25, "minimum": 1 }, "order": { "enum": [ "desc", "asc" ], "type": "string" }, "metric": { "type": "string" }, "season": { "type": "integer", "maximum": 2026, "minimum": 2016 }, "position": { "type": "string" }, "entity_kind": { "enum": [ "player", "team", "route", "personnel_group", "box_count", "rusher_count", "coverage_type", "regression_rule", "metric", "league" ], "type": "string" } } }arguments 47 linesverify_claim reads unknown never probed
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "claims" ], "properties": { "claims": { "type": "array", "items": { "type": "object", "required": [ "metric", "entity", "value" ], "properties": { "value": { "type": "number" }, "entity": { "type": "string" }, "metric": { "type": "string" }, "season": { "type": "integer", "maximum": 2026, "minimum": 2016 }, "entity_kind": { "enum": [ "player", "team", "route", "personnel_group", "box_count", "rusher_count", "coverage_type", "regression_rule", "metric", "league" ], "type": "string" } } }, "maxItems": 25, "minItems": 1 } } }arguments 53 linesrun_stat_query reads unknown never probed
Computes an NFL figure from a structured query rather than looking one up: a population (position, qualifying threshold), a window (seasons, weeks, a team span, a coach's tenure), one named measure, and one operation (leaders, rank, count, only-who, a per-season streak, or a share of a total). Answers questions the verified panel has no pre-computed row for — qualified superlatives, multi-season streaks, derived rates. Every response carries the executed method, the population size, the measure's definition and the data version it ran against. Figures are computed on request from nflverse data and are labelled as computed, not verified. A figure that cannot be served comes back with the reason and the nearest thing covered. Fantasy measures answer in the convention `scoring` names — "standard", "half_ppr" or "ppr" — and default to half-PPR when none is named; the response says which it used. A bare "PPR" means full PPR. measure.key takes a measure name ("rushing_yards", "half_ppr_points") or a verified panel metric key ("key_player_stats.rushing.yards", "fantasy_scoring.half_ppr_points"). A panel metric key this tool does not compute is refused with the reason.

One league's name, season, size, current week, detected scoring format, and the manager-to-roster map.

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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "league_id", "team" ], "properties": { "team": { "type": "string", "maxLength": 64, "minLength": 1 }, "week": { "type": "integer", "maximum": 18, "minimum": 1 }, "league_id": { "type": "string", "pattern": "^\\d{6,24}$" } } }arguments 24 linesget_entity_metrics reads unknown 7h ago
The verified figures 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. By default the headline figures for that player or team; scope "all" returns every figure held, and a named metric returns all of that metric's rows. Names are resolved against the players and teams Muffed holds; an unrecognised name returns the closest matches rather than a guess.

Muffed's published definition of a verified metric — what it measures, in plain language, from the glossary page for that term — plus which seasons it actually covers, how it is ranked, its licence and its attribution. Accepts a metric key or a common name ("cpoe", "rushing yards over expected"). Season coverage is often narrower than a decade — rushing yards over expectation exists from 2018 onward.

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.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id58fe6b14817786ad.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/58fe6b14817786ad/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
