## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 35
- drivers: +reachable +uptime-100% +updated-24d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 78/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: quote_buy (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); token_snapshot (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); verdict (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,211 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 7 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: 11, about 1,211 tokens to load them all
- tool set hash: a2d29b69df7d8de543c52d0072f8744d
- tools last changed: 2026-10-17T19:19:34.762Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.arbonomous/curvecall.svg)](https://protogrid.dev/servers/io.github.arbonomous/curvecall)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-17 `verdict` added
  - START HERE before buying a token. One call returns a buy / watch / avoid decision with the reasons, risk score, key numbers (price, liquidity, volume, age) and heuristic sizing and stop distance. $0.01 USDC. For full raw data use precheck. Heuristic screen, not financial advice.
- 2026-09-25 `bundle_check` added
  - Bundle/sniper signals for a token (base, bsc, robinhood, arc): who bought in the first blocks after launch, how much of the early supply they took, and whether any were funded by the deployer or a shared wallet. Signals, not advice. $0.02 USDC. Data by GeckoTerminal.
- 2026-09-25 `deployer_history` changed (description)
  - before: Deployer launch history on Base from CurveCall's hourly launch-outcome index (built since 2026-09-24): every launch this deployer made and how it ended (survived, rugged, died), with rug rate. Answers 'has this deployer rugged before?' $0.01 USDC. Data by GeckoTerminal.
  - after: Deployer launch history from CurveCall's hourly launch-outcome index on Base, Robinhood Chain and Arc (built since 2026-09-24): every launch this deployer made and how it ended (survived, rugged, died), with rug rate and dev-behavior flags (dev moved tokens, relaunch count). Answers 'has this deployer rugged before?' $0.01 USDC. Data by GeckoTerminal.
- 2026-09-24 `search_tokens` added
  - Search tokens by name, symbol or contract address across chains. $0.005 USDC.
- 2026-09-24 `deployer_history` added
  - Deployer launch history on Base from CurveCall's hourly launch-outcome index (built since 2026-09-24): every launch this deployer made and how it ended (survived, rugged, died), with rug rate. Answers 'has this deployer rugged before?' $0.01 USDC. Data by GeckoTerminal.
- 2026-09-24 `wallet_snapshot` added
  - On-chain wallet snapshot (EVM chains): contract or EOA, tx count, native balance, fresh-wallet flag. $0.005 USDC.
- 2026-09-24 `contract_check` added
  - On-chain contract check (EVM chains: base, ethereum, arbitrum, optimism, polygon, bsc): ownership renounced?, LP burn share, ERC-20 metadata, red flags. $0.01 USDC.
