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

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "groundtruth": {
      "type": "http",
      "url": "https://groundtruth-oracle.vercel.app/api/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-23d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (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: ground_truth_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); human_do (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); task_status (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 687 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`: 2 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: 4, about 687 tokens to load them all
- tool set hash: c1a61f2510400af57472c01adeb7c031
- tools last changed: 2026-09-26T23:13:55.438Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.unspecifiedcoder/groundtruth.svg)](https://protogrid.dev/servers/io.github.unspecifiedcoder/groundtruth)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (4)

- `ground_truth_info`: Get info about the GroundTruth ASP — what it does, pricing, and how to call it
- `human_do`: Create a task for a human oracle to complete in the real world. Requires x402 payment. Returns a task_id to poll with task_status.
- `review_task`: Review a submitted proof and accept or reject it. Accept releases the on-chain payout to the human oracle; reject fails the task with no payout. Call this after task_status shows the proof.
- `task_status`: Check the status and result of a GroundTruth task by its task_id
