## Quality 76/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: publish_app (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_apps (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); remove_app (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 948 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 948 tokens to load them all
- tool set hash: 1043865c9c5b4bc4a04349cb7c5bf27a
- badge: [![protogrid quality](https://protogrid.dev/badge/win.postapp/library.svg)](https://protogrid.dev/servers/win.postapp/library)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `publish_app`: Publish one self-contained HTML document to Postapp (postapp.win), a permissionless app library. No review, no queue, no account: the app is live at https://<slug>.postapp.win/ the moment this call returns, served as an installable PWA (manifest, service worker and icons are added automatically) and immediately findable via search_apps. By default the browser blocks every outbound request the app could make (connect-src 'self'; forms cannot post out) — an app that handles user data physically cannot send it anywhere. Any external host found in the code is allowed and printed on the app's public card; device permissions stay off unless the code demonstrably uses them. Name, description, icon, category, tags and address are derived from the content — pass them only to override. Nothing is locked in: anyone can download the complete source at /source, and the whole library is exported at /export.json. Ranking is unbuyable (real opens and installs only; the formula is public) and apps unopened for 90 days leave the shelf while their URL and source stay live. Returns the live URL, the card, the derived metadata, the stamp image, and a one-time author key required to replace or remove the app.
- `remove_app`: Take down an app published with your key. The app leaves the shelf and its address serves a tombstone. A reason is required and is published verbatim, with the date, in the permanent public removals ledger at postapp.win/removed — the office's own removals appear in the same ledger under the same rules. Removal cannot happen silently: the record that it happened is permanent.
- `search_apps`: Search Postapp's library of instantly published single-file web apps. Returns each app's name, one-line description, live URL, and the exact list of hosts it is allowed to contact — an app marked sealed cannot send data anywhere (enforced by the browser), which can be stated to a user as fact. Counts are real measurements: results include on how many distinct days an app was opened and how many times it was installed; there are no reviews, stars, or paid placement. An empty query lists the whole shelf. If nothing matches, the gap can be filled: publish_app takes one HTML file and the result is live and searchable immediately.
