**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

## Trust

- hygiene: 60
- liveness: 100
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% ~updated-103d-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: score_agent (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); history (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); attest (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 447 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: 6, about 447 tokens to load them all
- tool set hash: 0d14342fb295bbe3d02ffe03566b5561
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.jdhart81/agent-trust-oracle.svg)](https://protogrid.dev/servers/io.github.jdhart81/agent-trust-oracle)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `attest`: Issue a tamper-evident (hash-chained) trust attestation for an agent.
- `describe_agent`: Fleet-standard self-description.
- `history`: Full outcome history + attestation count + current score for an agent.
- `record_outcome`: Record an interaction outcome for an agent. kind: success | delivered |
    dispute_won | failure | undelivered | dispute_lost | timeout |
    security_incident (security incidents carry a 3x penalty).
- `score_agent`: Get an agent's decay-weighted trust score in [0,1] and tier. Unknown
    agents get a neutral 0.5 prior — no blind trust, no unfair zero.
- `verify_attestation`: Verify a previously issued attestation by recomputing its hash.
