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

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

- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 696 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

## Tools (3)

- `adjust_for_inflation`: Compare GBP purchasing power between years, with prices, wages and housing context. RPI covers 1948 onwards; CPI covers 1988 onwards. "now" means the latest stored observation, not a live price.
- `calculate_take_home`: Employee income tax and National Insurance for 2026/27, or the gross salary needed for a target net income. England, Wales and Northern Ireland only; Scotland is unsupported. Excludes pensions, student loans, benefits and other income. Includes a historical UK taxpayer income rank.
- `compare_public_spending`: Express a GBP amount as a share and duration of a stored 2025-26 public budget, with comparisons against other budgets. The NHS comparison uses England's DHSC day-to-day budget as a proxy. These are illustrative averages, not live spending rates.
