## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 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: 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: univ4_rfq_list_pools (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); univ4_rfq_quote_and_build_swap (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); univ4_rfq_get_quote (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 499 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 2 of the 7 days needed

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

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

- tools: 4, about 499 tokens to load them all
- tool set hash: 4bb77e465faa6a5bd219d106042644ee
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.lucascordone-spec/base-univ4-rfq-hook.svg)](https://protogrid.dev/servers/io.github.lucascordone-spec/base-univ4-rfq-hook)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `univ4_rfq_get_hookdata`: Retrieves the pre-fetched ECDSA-signed bytes hookData for a quoteId to pass to Uniswap v4 PoolManager.swap(key, params, hookData).
- `univ4_rfq_get_quote`: Sub-millisecond (<1ms) indicative quote from Chainlink On-Chain Oracles on Base Mainnet (-0.30% fee) and speculative KyberSwap route pre-fetch.
- `univ4_rfq_list_pools`: Lists all 21 initialized Uniswap v4 RFQ pools on Base Mainnet, live Chainlink oracle prices, and Morpho Blue flash liquidity stock.
- `univ4_rfq_quote_and_build_swap`: One-step Zero-Slippage Atomic Swap builder on Base Mainnet (Chain ID: 8453) via Uniswap v4 RFQ Hook (0xd72CD1d46bA05479583fbB561B558f133BA98088). Quotes flat Chainlink Oracle price (-0.30% fee, 0% AMM curve price impact) backed by $3.25B+ Morpho Blue & KyberSwap liquidity, and returns the exact PoolKey, SwapParams, and ECDSA-signed bytes hookData for PoolManager.swap.
