## Connection (mcpServers)

```json
{
  "mcpServers": {
    "hn-mcp-server": {

## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-2d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 84/100 (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: 86 (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
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: hn_get_thread (destructiveHint, idempotentHint, openWorldHint); hn_get_user (destructiveHint, idempotentHint, openWorldHint); hn_search_content (destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,267 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 9 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`: deps.dev does not know @cyanheads/hn-mcp-server@0.5.22, @cyanheads/hn-mcp-server@0.5.22

- tools: 4, about 2,267 tokens to load them all
- tool set hash: 995185fda3fc3068e8ba80aef26c23a6
- tools last changed: 2026-10-19T02:59:20.290Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.cyanheads/hn-mcp-server.svg)](https://protogrid.dev/servers/io.github.cyanheads/hn-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
