## Trust

- hygiene: 100
- liveness: 100
- freshness: 85

- 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 2025-06-18; 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: get_gas_demo (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_gas_basic (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_gas_premium (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 292 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 292 tokens to load them all
- tool set hash: ebf2baf631b44ae22e592c362652f03f
- badge: [![protogrid quality](https://protogrid.dev/badge/xyz.chain-ops/mgo.svg)](https://protogrid.dev/servers/xyz.chain-ops/mgo)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `get_cheapest_chain`: Get a direct recommendation for the cheapest EVM chain right now with savings %. Free, rate limited.
- `get_gas_basic`: Find the cheapest EVM chain before sending a transaction. Compares live gas across Ethereum, Base, Arbitrum & Optimism and returns the cheapest chain with savings % (e.g. 'Use Base — saves 99.8% vs Ethereum'). Use before bridging, deploying a contract, or any tx where you can choose the chain. $0.001 USDC via x402 on Base, no API key.
- `get_gas_demo`: Get free real-time gas prices for 4 major EVM chains (Ethereum, Base, Arbitrum, Optimism). Rate limited 10/hr.
- `get_gas_premium`: Find the cheapest EVM chain across 9 networks before transacting. Covers Ethereum, Base, Arbitrum, Optimism, BNB, Polygon, Avalanche, zkSync & Hyperliquid; returns the cheapest chain with savings % for cross-chain routing decisions. Use when you need the widest chain coverage to route a tx to the lowest-fee network. $0.002 USDC via x402 on Base, no API key.
