## Trust

- hygiene: 100
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% ~updated-81d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (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: 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: ens_expiry (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gas (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); token_unlocks (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,119 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`: no 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: 4, about 1,119 tokens to load them all
- tool set hash: 047e0257841b393f6f8daf38f28c8862
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.zvmzaretsky/fabtally-chain.svg)](https://protogrid.dev/servers/io.github.zvmzaretsky/fabtally-chain)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `ens_expiry`: PAID $0.001 (x402, USDC on Base). Resolve an ENS .eth or Basename .base.eth name's registration expiry ON-CHAIN (public RPC). Returns expiry date, days-left, whether it's in the 90-day grace period, the release date it becomes registrable again, and the current owner. Read-only, descriptive. Args: name. Without payment returns the x402 challenge; pass x_payment to settle.
- `gas`: PAID $0.001 (x402, USDC on Base). Current gas for a chain via public RPC: base fee + suggested priority + suggested max fee (gwei) at the latest block. If below_gwei is set, also returns whether the base fee is at/below your threshold right now. Read-only. Args: chain (ethereum|base|arbitrum|polygon|bsc|optimism), below_gwei (optional). Without payment returns the x402 challenge; pass x_payment to settle.
- `oracle_health`: PAID $0.003 (x402, USDC on Base). Chainlink price-feed health via public RPC: last-update age, latest answer (scaled by decimals), round monotonicity (is the answer current?), a stale flag vs the heartbeat, optional deviation vs a reference price, and per-factor flags. Read-only, descriptive. Args: feed_address, chain, heartbeat_seconds (optional), reference (optional). Without payment returns the x402 challenge; pass x_payment.
- `token_unlocks`: PAID $0.003 (x402, USDC on Base). Next token vesting/unlock event(s) from DefiLlama's PUBLIC emissions dataset: upcoming unlock date(s), token amount, and % of max supply, with a human description. Cleanly says so when a token has no public unlock schedule. Read-only, descriptive — NOT a price signal. Args: token (symbol, protocol name, or contract address), chain (optional, for address lookup). Without payment returns the x402 challenge; pass x_payment to settle.
