## Trust

- hygiene: 100
- liveness: 99
- freshness: 100
- provenance: 85
- drivers: +repository +dns-namespace +website +reachable +uptime-97% +updated-29d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 85/100 (good)

### 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`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 819 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`: 3 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: 4, about 819 tokens to load them all
- tool set hash: 9310cad0cbe9a85221f95c71bda82856
- tools last changed: 2026-09-27T15:57:44.981Z
- badge: [![protogrid quality](https://protogrid.dev/badge/art.maddegen.agent/solsnap.svg)](https://protogrid.dev/servers/art.maddegen.agent/solsnap)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-27 `wallet_sweep_report` changed (title, description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Check whether payment for a wallet_sweep full report has settled. Returns 'not_paid' or the full itemised JSON report once payment is confirmed.
  - after: Legacy alias of wallet_sweep kept for older clients: returns status=full with every holding once the wallet's payment has settled, otherwise status=not_paid with payment details. Prefer wallet_sweep. Errors (isError=true): malformed address.
- 2026-09-27 `wallet_sweep_pay` changed (title, description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Get the exact SOL amount and payment address to unlock the full itemised wallet_sweep report for one wallet. Send the exact amount shown; poll wallet_sweep_report afterwards.
  - after: Optional helper: returns only the SOL amount and address that unlock the full wallet_sweep report for one wallet (the same details wallet_sweep already includes when unpaid). Send the exact amount; then call wallet_sweep again. Errors (isError=true): malformed address.
- 2026-09-27 `wallet_sweep` changed (title, description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Score every SPL token a Solana wallet holds for rug-risk. Free tier returns totals plus the 3 riskiest holdings named. Full itemised report for every token held costs $1 in SOL - call wallet_sweep_pay to get the exact amount and address.
  - after: Grade every token a Solana wallet holds for rug risk in one call (up to 40 holdings). Free: totals plus the 3 riskiest holdings. Paid ($1 in SOL, one time per wallet): every holding itemised. This one tool covers the whole paid flow: an unpaid result includes payment.pay_to and payment.amount_sol; send exactly that amount (the amount identifies the wallet), then call wallet_sweep again with the same address and it returns status=full once the payment is seen on chain (usually within 30 s). Use solsnap_scan for a single token. Errors (isError=true): malformed address. Empty wallets return tokens_held=0.
- 2026-09-27 `solsnap_scan` changed (title, description, inputSchema, outputSchema, annotations)
  - before: Score a single Solana token mint for rug-risk: mint and freeze authority, Token-2022 traps (transfer fees, hooks, permanent delegate, pause), mutable metadata, pump.fun curve status, top-holder concentration (wallets vs pools), liquidity depth, pair age, FDV/liquidity ratio, 24h volume/liquidity, buy/sell flow imbalance, pair count. Does not check LP locks. Returns a 0-100 safety score, letter grade and itemised flags. Free, read-only, sourced live from Solana RPC and DexScreener.
  - after: Grade one Solana token mint for rug risk: 0-100 safety score, A-F grade and itemised flags. Free. Checks mint/freeze authority, Token-2022 traps (transfer fee, hook, permanent delegate, pause), mutable metadata, pump.fun curve status, top-holder concentration (wallets vs pools), liquidity, pair age, FDV/liquidity, volume/liquidity, buy/sell imbalance. Does NOT check LP locks. Use it before buying one token; to grade everything a wallet holds use wallet_sweep instead. Unknown or unlisted mints still return on-chain checks with found=false. Errors (isError=true): malformed mint. Live data from Solana RPC + DexScreener, typically 1-4 s.
