- liveness: 99
- freshness: 100
- provenance: 100

## Quality 73/100 (needs work)

### 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: token_audit (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); swap_quote_and_build (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); orderbook_imbalance (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 711 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 6 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 711 tokens to load them all
- tool set hash: d139edfe056e7db99686d1d38f62d825
- tools last changed: 2026-10-17T22:10:00.190Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.skinwinking/agent-tollgate.svg)](https://protogrid.dev/servers/com.skinwinking/agent-tollgate)
- 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 `swap_quote_and_build` changed (description)
  - before: Same-chain Solana swaps route through Jupiter with a referral fee account. Cross-chain and EVM swaps route through LI.FI with an integrator fee. The response contains a serialized unsigned transaction to be signed and broadcast by the caller.
  - after: Free to call. Returns the best route and an unsigned transaction, and for Solana swaps a rug-pull risk check of the output token (mint/freeze authority, token-2022 traps, holder concentration) so agents do not buy honeypots. Same-chain Solana swaps route through Jupiter with a referral fee account. Cross-chain and EVM swaps route through LI.FI with an integrator fee. The response contains a serialized unsigned transaction to be signed and broadcast by the caller. A 30 bps platform fee is embedded in the route.
- 2026-10-17 `token_audit` changed (description)
  - before: Inspects mint and freeze authority, token-2022 extensions, proxy and ownership state, privileged functions and top holder concentration. Returns a 0-100 risk score with itemised flags. Paid: 0.20 USDC per call via x402.
  - after: Rug-pull / honeypot check before you buy a token. Inspects mint and freeze authority, token-2022 extensions, proxy and ownership state, privileged functions and top holder concentration. Returns a 0-100 risk score with itemised flags. First 3 calls per day free, then 0.20 USDC per call via x402.
- 2026-10-17 `orderbook_imbalance` changed (description)
  - before: Aggregates spot order book depth and returns bid/ask notional within 10/25/50/100 bps of mid, signed imbalance in [-1,1], largest liquidity walls and a directional signal. Paid: 0.02 USDC per call via x402.
  - after: Aggregates spot order book depth and returns bid/ask notional within 10/25/50/100 bps of mid, signed imbalance in [-1,1], largest liquidity walls and a directional signal. First 3 calls per day free, then 0.02 USDC per call via x402.
