## Quality 80/100 (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: 75 (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: get_quote (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); token_risk (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wallet_portfolio (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 559 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### 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
- pass `stability.new_links`: no tool change named a new site

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know advan-mcp@0.1.0

- tools: 4, about 559 tokens to load them all
- tool set hash: 4014c8a15da86f38deb6ac7cde9c28d7
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.solaradex/advan.svg)](https://protogrid.dev/servers/io.github.solaradex/advan)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `build_swap_tx`: Free. Returns an UNSIGNED base64 transaction for the taker wallet to sign. Advan never signs and never holds keys. Default (selfBroadcast false) keeps JupiterZ routes, which need Jupiter POST /swap/v2/execute to add the market-maker co-signature. Pass selfBroadcast true to exclude jupiterz so the taker can broadcast the signed transaction.
- `get_quote`: Free Jupiter Swap API V2 quote (GET /swap/v2/order, no taker). Returns amounts, route, slippage, and referral fee fields. Does not return a transaction.
- `token_risk`: Paid token risk report ($0.02 USDC via x402 exact on solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). Combines RPC mint/freeze authority, Jupiter Tokens V2, and RugCheck. Ordinary MCP clients that cannot pay receive a payment-required error.
- `wallet_portfolio`: Paid wallet portfolio ($0.02 USDC via x402 exact). SOL plus SPL Token and Token-2022 balances, priced with Jupiter Price V3.
