## Quality 85/100 (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: 86 (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`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_tool_status (destructiveHint, idempotentHint); get_runtime_tools (destructiveHint, idempotentHint); base_token_allowance (idempotentHint); …
- pass `tools.token_cost`: about 936 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 3 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: 6, about 936 tokens to load them all
- tool set hash: d4f72b92ca756a3e4374c8108f09a340

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `base_uniswap_v3_lp_accounting_audit` added
  - Read official Base Uniswap V3 NFT and pool state at one canonical block hash. Reconcile exact token inventory and fee-growth checkpoints against optional reported raw amounts. Return signed discrepancies, reproducible inputs and uint128 accounting semantics. Recorded tokensOwed may include withdrawn principal, not only fees. Read-only; no USD valuation, trading, custody or profitability claim. Version 234e52e42b53afb8. Requires 0.01 native USDC per call on Base; shared paid pilot limits apply.
- 2026-10-12 `base_token_allowance` changed (description)
  - before: Read an ERC-20 allowance on Base at a pinned block before an AI proposes spending. Returns exact units, decimals and provenance. Does not approve or transfer tokens. Version 253064e6ce6110d8. Requires 0.01 native USDC on Base; shared paid pilot limits apply.
  - after: Read an ERC-20 allowance on Base at a pinned block before an AI proposes spending. Returns exact units, decimals and provenance. Does not approve or transfer tokens. Version 253064e6ce6110d8. Requires 0.01 native USDC per call on Base; shared paid pilot limits apply.
- 2026-10-12 `get_runtime_tools` changed (description)
  - before: List mounted tool versions and input schemas. Free. Releases share the existing paid pilot price, receiver and limits.
  - after: List mounted tool versions, per-call USDC prices and input schemas. Free. Releases share the receiving wallet and pilot limits, not a universal price.
