## Quality 73/100 (needs work)

### 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 declares ttlMs 0, so clients re-fetch it on every use

### 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: 71 (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
- 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: find_best_australian_exchange (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_where_to_buy_crypto (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 834 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 50 (weight 15)

- pass `stability.changes`: 4 tool changes in 30 days
- fail `stability.rug_pull`: 4 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 2, about 834 tokens to load them all
- tool set hash: e63e0d098231190e055d381996059469
- tools last changed: 2026-10-11T03:35:57.534Z
- badge: [![protogrid quality](https://protogrid.dev/badge/au.com.cryptobuddy/cryptobuddy.svg)](https://protogrid.dev/servers/au.com.cryptobuddy/cryptobuddy)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-11 `find_where_to_buy_crypto` changed (description) **meaning changed**
  - before: Find Australian exchanges offering a cryptocurrency for an AUD purchase amount. Use find_best_australian_exchange to compare a specified buy or sell direction. Returns CryptoBuddy API JSON as text; quoted outcomes are estimates and this tool places no exchange order. Paid data access uses XRP on XRPL Mainnet. Call without paymentSignature to obtain an x402 v2 challenge. An authorised compatible payer must create the base64 PAYMENT-SIGNATURE value for that exact resource, then call this tool again with identical purchase inputs and that value. Forwarding this value may settle the data-access payment. This server does not create or sign payments. HTTP 402 returns payment requirements; other failures return isError. Do not automatically pay again after a failed or timed-out paid request.
  - after: Find Australian cryptocurrency exchanges offering a specified cryptocurrency for purchase using AUD. Use this tool when the user wants to know where an asset can be bought or which Australian exchanges offer it. For comparing the best estimated buy or sell outcome across exchanges, use find_best_australian_exchange instead. Results are estimates and do not place orders. This is a paid data-access tool using XRP on XRPL Mainnet. First call without paymentSignature to receive an x402 v2 payment challenge. An authorised compatible payer must generate PAYMENT-SIGNATURE for the exact resource and retry with identical inputs. Never supply wallet secrets. This server does not sign or initiate payments. If payment fails or times out, verify settlement before retrying.
