**An agent can connect on its own if it already holds `EJENTUM_MCP_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "ejentum-mcp": {
      "type": "http",
      "url": "https://api.ejentum.com/mcp",
      "headers": {
        "Authorization": "Bearer ${EJENTUM_MCP_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${EJENTUM_MCP_TOKEN}`.

## Trust

- hygiene: 100
- liveness: 98
- freshness: 65

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 77/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 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: ejentum_scaffold (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ejentum_domains (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ejentum_graph (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 477 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: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: ejentum-mcp@0.2.2 resolved: 98 packages

- tools: 4, about 477 tokens to load them all
- tool set hash: 85bba3761b0c5a84e9375c866c13466c
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ejentum/ejentum-mcp.svg)](https://protogrid.dev/servers/io.github.ejentum/ejentum-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
