## Quality 96/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### 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: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,960 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: 8, about 1,960 tokens to load them all
- tool set hash: e2586c80af7e49cb89031d19cb033c34
- badge: [![protogrid quality](https://protogrid.dev/badge/art.maddegen.agent/synapse-world.svg)](https://protogrid.dev/servers/art.maddegen.agent/synapse-world)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `country_info`: Any country's essentials: capital, population, GDP and GDP per capita (World Bank), currencies, languages, calling code, internet TLD, time zones, driving side, borders, flag. Static facts from the world-countries dataset (no rate limits) plus the latest World Bank population and GDP figures. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `earthquakes`: Earthquakes worldwide from the last hour to 30 days, filtered by minimum magnitude and optionally within a radius of a place — with depth, tsunami flag and USGS alert level. USGS real-time earthquake feeds (updated every minute). Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `fx_rates`: Official exchange rates for 30 major currencies (European Central Bank reference rates): latest or any date since 1999, convert an amount, or a time series. Frankfurter API over ECB reference rates, published each working day ~16:00 CET. For crypto use crypto_price. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `geocode`: Place name or address → coordinates (with city, state, country, postcode), or lat,lon → the nearest address. Up to 10 candidates. OpenStreetMap data via Photon. Returns OSM links so results can be checked. When to use: To turn names into coordinates; weather and sun_moon accept place names directly. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `holidays`: Public holidays for 100+ countries for any year, whether today is a holiday there, and the next upcoming ones — including regional (state) holidays. Nager.Date open holiday data. Use for scheduling, market-closure awareness or delivery estimates. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `sun_moon`: Sunrise, sunset, golden hour, twilight, day length and solar noon for any place and date — plus moon phase, illumination, moonrise and moonset. Astronomical calculation (SunCalc), exact and instant. Pass tz for local times. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `time_convert`: Current time in any time zones, convert a time between zones (DST-correct), and date arithmetic: add/subtract durations, days between dates, weekday, ISO week, Unix time. Computed locally from the IANA time-zone database — no rate limits, exact. Zones are IANA names (America/New_York, Asia/Tokyo, UTC). Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
- `weather`: Current weather and hourly/daily forecast for any place name or lat,lon: temperature, feels-like, wind, gusts, rain, cloud, humidity, UV — up to 9 days. Forecast from the Norwegian Meteorological Institute (MET Norway), the same model data yr.no uses, worldwide. Place names are geocoded with OpenStreetMap. Times are UTC plus local time when tz is given (IANA, e.g. Australia/Sydney). Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
