Overview

Description from the maker (original English)

MCP deprecation radar: witnessed, hash-chained registry snapshots prove deprecated/removed tools.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

The maker has not listed install details in the registry. See the maker’s README below.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is Eclipse Sunset safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

Eclipse Sunset

MCP deprecation radar — detects deprecated/removed tools and versions from witnessed registry snapshots and generates a migration diff for an agent's config.

Scope label: LOCAL / fixture. v0.1 ingests local registry snapshot JSON files only. It does not crawl live registries. Live crawling is a later phase.

Status: v0.1.1 — CERTIFIED (local, fixture) (Verity re-bench, 2026-10-26: probe 5 chain-attack suite 4/4 + strict extras 9/9, full prior suite 44/44; D1 closed). Spec: SPEC.md.

Novel mechanism

Sunset notices are witnessed against registry history, so a "deprecated" claim is provable — and the migration diff is generated from the witnessed before/after schemas, not scraped docs.

Each ingested snapshot is SHA-256 hashed over its canonical JSON and hash-chained in ingest order (chain_hash = sha256(prev_hash + snapshot_hash)). Findings cite both snapshot hashes of the witnessed pair. A claim with no witnessed pair behind it returns UNPROVEN.

Tools (exactly 5)

ToolWhat it does
ingest_snapshotValidate a snapshot (server_id, version, tools[] with name/inputSchema/deprecated), hash it, chain-append it; returns snapshot id + chain position.
detect_sunsetsBetween two witnessed snapshots of the same server: tools removed, tools newly deprecated, version changes, schema-breaking changes — each finding cites both snapshot hashes.
migration_diffGiven a server + an agent config listing tools used, produce the diff: which used tools are sunset in the newer witnessed snapshot and what changed in their schemas.
verify_sunset_claimClaim "tool X deprecated/removed" → PROVEN only if a witnessed snapshot pair supports it, else UNPROVEN.
chain_statusVerify hash-chain integrity (recomputes every hash + link; tamper → valid: false).

Fixtures

fixtures/weather-v1.json and fixtures/weather-v2.json: the same fixture server at v1.0.0 / v2.0.0 — one tool removed (legacy_lookup), one deprecated (get_alerts), one schema-breaking change (get_forecast gains required units), one unchanged (convert_units). fixtures/agent-config.json is a sample agent config for migration_diff.

Pricing

FREE + funnel role — free radar feeds paid listing-hygiene and re-bench work. No payment anything in this server.

Run

python3 server.py            # MCP over stdio JSON-RPC

python3 -m unittest discover -s tests -v

State (the witnessed chain ledger) lives in data/ or the directory named by SUNSET_DATA_DIR.
