- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 77/100 (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: escrow_dispute (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); escrow_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); safe_pay (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,922 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: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 111 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: paycrow@1.0.0 resolved: 111 packages

- tools: 10, about 1,922 tokens to load them all
- tool set hash: fed12354bf23abeeb0a30bf4d28193be
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.michu5696/paycrow.svg)](https://protogrid.dev/servers/io.github.michu5696/paycrow)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (10)

- `escrow_create`: Create a USDC escrow with built-in dispute resolution. Funds are locked on-chain until delivery is confirmed (release) or a problem is flagged (dispute). If disputed, an arbiter reviews and rules — the only escrow service with real dispute resolution on Base.
- `escrow_dispute`: Flag a problem with delivery — PayCrow's key differentiator. Locks escrowed funds and triggers arbiter review. Unlike other escrow services that say 'no disputes, no chargebacks', PayCrow has real on-chain dispute resolution. Use when service was not delivered or quality was unacceptable.
- `escrow_release`: Confirm delivery and release escrowed USDC to the seller. Only call this when you've verified the service/product was delivered correctly.
- `escrow_status`: Check the current state of an escrow (funded, released, disputed, expired, etc.)
- `rate_service`: Rate a completed escrow. After escrow_release, rate the seller's service quality (1-5 stars).

This builds the reputation data that makes PayCrow's trust scores meaningful over time.
Both sides can rate: buyer rates seller's service quality, seller rates buyer's conduct.

Ratings are on-chain and permanent — they feed directly into trust scoring.
- `safe_pay`: The smart way to pay an agent. Checks their trust score first, then auto-configures escrow protection based on risk.

Flow: Check trust → Set protection level → Create escrow → Call API → Verify → Auto-release or auto-dispute.

Protection levels (automatic):
- High trust agent → 15min timelock, proceed normally
- Moderate trust → 60min timelock, payment capped at $25
- Low trust → 4hr timelock, payment capped at $5
- Unknown/caution → BLOCKED — will not send funds

This is the recommended tool for paying any agent. If you need manual control, use x402_protected_call instead.
- `trust_gate`: Should you pay this agent? Check before sending money. Returns a go/no-go decision with recommended escrow protection parameters.

Unlike other trust services, PayCrow ties trust directly to escrow protection:
- High trust → shorter timelock, proceed with confidence
- Low trust → longer timelock, smaller amounts recommended
- Caution → don't proceed, or use maximum protection

This is the tool to call BEFORE escrow_create or safe_pay.
- `trust_onchain_quick`: Quick on-chain reputation check using only the PayCrow Reputation contract. Free, no API keys needed. Use trust_score_query for the full composite score.
- `trust_score_query`: Full trust score breakdown for an agent address. Aggregates 4 on-chain sources: PayCrow escrow history, ERC-8004 agent identity, Moltbook social karma, and Base chain activity. Returns 0-100 score with per-source details. For a quick go/no-go decision, use trust_gate instead.
- `x402_protected_call`: Make an HTTP API call with manual escrow protection. Full control over verification and timelock parameters.

For most payments, use safe_pay instead — it auto-configures protection based on seller trust.

Use x402_protected_call when you need:
- Custom JSON Schema verification (not just "valid JSON + 2xx")
- Hash-lock verification (exact response match)
- Specific timelock durations
- To override safe_pay's trust-based amount limits
