## Connection (mcpServers)

```json
{
  "mcpServers": {
    "privi-anchor": {
      "type": "http",

## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% +updated-1d-ago -duplicate-repo(3 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 90/100 (new)

### 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: 93 (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
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 1 of 4 tools declare all four hints; missing: anchor_status (destructiveHint, idempotentHint); anchor_hash_text (destructiveHint, idempotentHint); anchor_verify (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 490 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 0 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: 4, about 490 tokens to load them all
- tool set hash: 49bdb43ee05ccc631a155c02d15a32f8
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.canoydario847-cloud/privi-anchor.svg)](https://protogrid.dev/servers/io.github.canoydario847-cloud/privi-anchor)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `anchor_hashes`: Anchor up to 100 hashes on the Privi chain in one transaction. Returns, for each hash, a
receipt (tx_hash, Merkle proof, block, time) that anyone can check with anchor_verify.
Requires an API key (Authorization: Bearer).
- `anchor_hash_text`: SHA-256 of a piece of text, ready to pass to anchor_hashes. Hashing happens here; nothing is stored.
- `anchor_status`: Which chain anchors go to, the service wallet that signs them, its gas balance, and totals.
- `anchor_verify`: Check on the blockchain that a hash was anchored, by whom and when. Free.
With tx_hash and proof from a receipt, the check uses only chain data.
