## 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: get_syri_score (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_syri_venues (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_syri_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 320 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: 3, about 320 tokens to load them all
- tool set hash: dc9aee5331e5b9727847d3b1e0e5621a
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.rfsrisk/syri.svg)](https://protogrid.dev/servers/ai.rfsrisk/syri)

## Tools (3)

- `get_syri_score`: PAID: $0.05 USDC on Base per venue, via x402. Returns the risk band (Conservative / Moderate / Speculative) and 0-100 composite. Called without payment, this returns the payment terms rather than the score — that is the expected first response, not a failure. If you can settle x402 payments, pass the encoded authorization as x_payment to receive the score.
- `get_syri_status`: Free. Reports whether the service is healthy, which network it settles on, how many venues are scored, and how old the data is. Useful before depending on a score.
- `list_syri_venues`: Free. Returns every venue RFS currently scores, with pricing, payment terms and data freshness. Venues outside this list return an error and are never charged.
