Description from the maker (original English)
The insurance watcher — signals your policies' expiries before they happen. It does not insure

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

Eclipse Beacon — the insurance watcher: it watches your household's policies, signals expiries before they happen, and prepares the actions you approve. It does not insure, bind, or advise.
A household's insurance — health, auto, home, life — has no system of record. Policies live as PDFs in email and paper in a drawer, and expiries are usually discovered by a lapse notice. Beacon B0 is the watcher that fixes the first half of that: a local policy graph with provenance on every field, and an expiry radar that signals deadlines *before* they arrive.
v0.1.0, phase B0 only (personal edition: policy graph + expiry radar). Read/watch only. Local stdio transport, Python stdlib only, no network calls anywhere in the code, and the shipped fixtures are synthetic (fictional carriers, synthetic people, invented policy numbers). No certification claimed — bench pending.
Explicitly NOT in v0.1, by spec: renewal shopping, renewal prep, claims filing, proof delivery, binding, cancelling, paying — and the entire agency edition, which is gated behind counsel + licensing review. Binding, negotiating, and advising for others are state-licensed producer activities; Beacon's personal edition acts only on the owner's own household data, and B0 doesn't even do that — it watches.
| Tool | What it does |
|---|---|
policy_ingest | Parse a declarations-page-style document (JSON, or simple text dec page) from a local file. Returns a draft + diff with per-field provenance (source file, locator, confidence). Propose-only by default — nothing is written unless `confirm=true`. Also ingests household_profile JSON (asset/person declarations). |
policy_list | Every policy in the graph with key dates, plus declared assets/persons and current alert windows. |
policy_get | One policy in full, provenance included. |
radar_report | Ranked upcoming events: renewal (≤60d), premium due (≤14d), grace-period end, escrow/lender proof deadline, and static enrollment calendar entries (ACA / Medicare — dates move yearly, flagged [verify] on the surface). Each event carries severity, days-until, the consequence of missing it, and the provenance of the date it came from. |
gap_report | Read-only analysis: assets with no covering policy, duplicate coverage on the same asset, premium spikes vs the prior term (default flag >15%). Findings are signals with evidence — never verdicts, never advice. |
Alert windows are owner-configurable, but a change may only tighten a window — lengthen its lead time so Beacon warns *earlier*. Any attempt to loosen a window (warn later, narrower net) is rejected with the reason named. The watcher never quietly gives you less warning.
Every ingest proposal, merge, radar run and gap run appends a hash-chained receipt to the store — append-only and machine-verifiable (verify_receipt_chain). Proposals are receipted too: the audit trail covers what was *attempted*, not just what landed.
python3 server.py # MCP over stdio, stdlib only, no dependencies
python3 smoke.py # end-to-end smoke over real stdio (temp state) python3 -m unittest discover tests # 17 tests
State persists in data/state.json beside the server (override with ECLIPSE_BEACON_STATE). data/ is gitignored — a real household's graph never belongs in a repo.
fixtures/ ships four synthetic policies — auto, homeowners, health, term life — each as an ACORD-shaped JSON dec page and an equivalent simple-text dec page (the two parse to identical drafts; a test proves it), plus household.json declaring the household's assets and persons — including one boat that no policy covers, so the gap report has something honest to find.
