## Trust

- hygiene: 60
- liveness: 100
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% ~updated-87d-ago -duplicate-repo(32 names)
- 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 2025-11-25; 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: fund_escrow (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_escrows (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); refund_escrow (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 765 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: 9, about 765 tokens to load them all
- tool set hash: 682eb2b0f0fc3fc122a28200a957bef9
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.jdhart81/agent-escrow.svg)](https://protogrid.dev/servers/io.github.jdhart81/agent-escrow)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (9)

- `describe_agent`: Fleet-standard self-description.
- `dispute_escrow`: Move a FUNDED escrow to DISPUTED. An arbiter (agent-arbitration-agent)
    then resolves it to release or refund.
- `escrow_status`: Current record for an escrow.
- `fund_escrow`: Mark an OPEN escrow as FUNDED (idempotent). payment_ref links the
    payment-rail transaction.
- `list_escrows`: List escrows, optionally filtered by state
    (OPEN|FUNDED|RELEASED|REFUNDED|DISPUTED).
- `open_escrow`: Open an escrow between payer and payee. amount_minor is a positive
    integer in minor units (cents). The platform fee is computed and FROZEN at
    open (ceil bps). Returns the escrow_id (state OPEN). RETRY-SAFE: pass
    open_ref=<your job id> and a replayed open returns the ORIGINAL escrow
    (duplicate=true) instead of minting another one (E10).
- `refund_escrow`: Refund an OPEN/FUNDED/DISPUTED escrow to the payer (exactly-once).
    Refunding an OPEN escrow is a cancel.
- `release_escrow`: Release a FUNDED/DISPUTED escrow to the payee (exactly-once — a repeat
    release returns the existing terminal record, never a double payout).
- `verify_audit`: Validate the tamper-evident audit hash chain for an escrow.
