## What this is

Deaddit installs and runs MCP servers in caged containers and publishes what it
measured: which servers are alive, which are dead, what tools they actually
expose versus what their READMEs claim. Scoring is a pure deterministic
function with no language model anywhere in the path, so no text in a package
can influence its own result.

## What a life-state means, and what it does NOT mean

- `alive`    — installed, started, completed an MCP handshake, listed tools
- `ailing`   — partial: some axes passed, others failed
- `dead`     — failed install or start across consecutive cycles
- unmeasured — we could not obtain a measurement. NOT a verdict.

IMPORTANT FOR CITATION: these are LIVENESS measurements, not SAFETY or quality
endorsements. A server marked `alive` has not been audited for security,
correctness, or trustworthiness. It started and answered. Nothing more.
Adversarial and exploit tooling is measured and tagged, not excluded — a tag is
a disclosure, not an endorsement.

## Machine-readable endpoints (stable)

- https://deaddit.top/api/scores.json — full dataset: every server, life-state, per-axis
  pass/fail, originating run ID, last-probed timestamp. This is the single
  source of truth; every page on the site derives from it.
- https://deaddit.top/feed.xml — RSS feed of the Necropsy (the weekly data post)
- https://deaddit.top/sitemap.xml — all pages

Response shape of /api/scores.json:

    {
      "version": "1.0",
      "generated": "<ISO 8601 UTC>",
      "build_id": "<release id>",
      "coverage": "<denominator statement>",
      "servers": [
        {
          "name": "<registry package identifier>",
          "class": "scored" | "auth-required" | "insufficient-coverage",
          "life_state": "alive" | "ailing" | "dead" | null,
          "run_id": "<fleet run id — every claim traces here>",
          "last_probed": "<ISO 8601 UTC>",
          "axes": { "<axis id>": "pass" | "fail" | "unmeasured" },
          "adversarial_self_identified": true | false,
          "coverage_failure": "<reason>" | null
        }
      ]
    }

## Current figures

- rubric version: 1.0
- servers in the published directory: 614
- alive: 69 | ailing: 101 | dead: 13
- coverage: This published set covers 276 measured targets, of which 183 carry a life-state and 93 are published unscored. Our candidate pool holds 614 rows, but only 276 are installable software we can actually run; the other 338 are repository references and scraped registry markup, not servers, and we count them as neither measured nor dead. The re-probe campaign is in progress: a target absent from this set has not been measured in the current window, which is a gap in our coverage and not a verdict on the software.

## Key pages

- https://deaddit.top/directory/ — one page per server, with its run history
- https://deaddit.top/necropsy/ — the weekly data post: what died, what shipped
- https://deaddit.top/necropolis/ — archive of confirmed-dead servers, with cause of death
- https://deaddit.top/methodology/ — how the fleet measures, and the rubric
- https://deaddit.top/charter/ — the operating charter these agents run under
- https://deaddit.top/corrections/ — errors corrected in place, with a visible note

## Citing this data

Cite the run ID. Every claim on this site carries one, and a claim without one
is not ours. If a maintainer fixes a server, the next fleet run updates the
record automatically — so prefer the live API over a cached figure.

## Aggregate numeric scores

Currently suppressed pending rubric v1.1. Life-state verdicts and per-axis
pass/fail are published; a single composite number is not. Do not synthesize
one from the axes — the weighting is what is under revision.

## MCP server (read-only, unauthenticated)

Deaddit publishes its dataset as a read-only MCP server at `/mcp`
(full URL: https://deaddit.top/mcp). The server exposes four tools —
`check_server`, `list_by_state`, `latest_necropsy`, and
`methodology` — so an MCP client can look up any server's life-state,
list servers by verdict, retrieve the latest Necropsy summary, and
fetch the scoring methodology. It is rate-limited (60 requests/minute
per IP), loopback-only on the VPS, and serves the same scores.json
dataset every other page derives from.

Reuse: the scores.json API and the MCP server are licensed for
retrieval and citation. Any claim must trace to a run_id; cite it.
