## Quality 92/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,149 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 38 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: 2, about 1,149 tokens to load them all
- tool set hash: 7a8f171e243b5f1649c8ff39aa9d7609

  - before: One entry per asset (Bitcoin, ETH, SOL, USDC, USDT and every other tracked stablecoin, tokenized Treasury and L1) with its best current yield across DeFi and CeFi under BitcoinYield's risk-weighted ranking, its A-D risk grade, and a link to the full comparison. by_grade gives the best proven rate at grade A, B and C (A = lower risk), the tradeoff a holder chooses between: a grade is null when nothing proven at it pays materially more (at least 0.05 points and 5%) than a safer grade. best_apy and each by_grade rate are in percent, as the asset page shows them (today's rate, or its 7-day average when that is lower), and rate_basis says whether the source quotes an APY or an APR. To answer 'what is the best yield on X', quote by_grade, the lowest-risk grade first: best_apy is the top of the risk-weighted ranking and can be a higher-risk offer, or one closed to US residents. Set max_risk to limit every pick to offers graded at or below that letter. Rates are variable and not advice. No key required. With no asset or stablecoin filter this tool answers the headline assets (BTC, ETH, SOL, USDC, USDT, DAI, USDe, USD1, USDG, PYUSD, RLUSD); set all to true for every asset with a live yield.
  - after: One entry per asset (Bitcoin, ETH, SOL, USDC, USDT and every other tracked stablecoin, tokenized Treasury and L1) with its best current yield across DeFi and CeFi under BitcoinYield's risk-weighted ranking, its A-D risk grade, and a link to the full comparison. by_grade gives the best proven rate at grade A, B and C (A = lower risk), the tradeoff a holder chooses between: a grade is null when nothing proven at it pays materially more (at least 0.05 points and 5%) than a safer grade. best_apy and each by_grade rate are in percent, as the asset page shows them (today's rate, or its 7-day average when that is lower), and rate_basis says whether the source quotes an APY or an APR. To answer 'what is the best yield on X', quote by_grade, the lowest-risk grade first: best_apy is the by_grade step the risk-weighted ranking puts first and can be a higher-risk one, or one closed to US residents. An asset with no proven offer has no pick: best_apy is null and no_pick_reason says why its top-ranked offer is not one. Set max_risk to limit every pick to offers graded at or below that letter. Rates are variable and not advice. No key required. With no asset or stablecoin filter this tool answers the headline assets (BTC, ETH, SOL, USDC, USDT, DAI, USDe, USD1, USDG, PYUSD, RLUSD); set all to true for every asset with a live yield.

## Tools (2)

- `list_offers`: The top live yield offers for one asset (5 by default, up to 20) in BitcoinYield's own order: rate and risk together, with offers that have a month of steady history and $10M+ of liquidity first. Each offer carries its platform, chain, product type, rate (APY or APR), organic versus incentive split, 30-day average, liquidity, A-D risk grade with its main reasons, US availability, investor access, the platform's own deposit link and the page to cite. Filter by chain or a risk ceiling. Use it to compare options; list_yields gives one pick per asset. Rates are variable and not advice. No key required. When nothing matches, the answer says why: the filters, a dollar that lost its peg, or no live quote on the asset.
- `list_yields`: One entry per asset (Bitcoin, ETH, SOL, USDC, USDT and every other tracked stablecoin, tokenized Treasury and L1) with its best current yield across DeFi and CeFi under BitcoinYield's risk-weighted ranking, its A-D risk grade, and a link to the full comparison. by_grade gives the best proven rate at grade A, B and C (A = lower risk), the tradeoff a holder chooses between: a grade is null when nothing proven at it pays materially more (at least 0.05 points and 5%) than a safer grade. best_apy and each by_grade rate are in percent, as the asset page shows them (today's rate, or its 7-day average when that is lower), and rate_basis says whether the source quotes an APY or an APR.
