# Cyphrex

> Blockchain SSN for AI agents. MCP gateway that blocks at the point of action, tamper evident audit.

- version: 0.2.1
- connection class: R1 (autonomous)
- trust: 90/100
- quality: 79/100 (good)

**An agent can connect on its own if it already holds `CYPHREX_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": {
    "cyphrex-mcp": {
      "type": "http",
      "url": "https://mcp.cyphrex.io/mcp",
      "headers": {
        "Authorization": "Bearer ${CYPHREX_MCP_TOKEN}"
      }
    }
  }
}
```

Placeholders to fill: `${CYPHREX_MCP_TOKEN}`.

## Trust

- hygiene: 100
- liveness: 98
- freshness: 85
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-96% ~updated-65d-ago
- 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: get_audit_log (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_behavior_profile (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_mcp_tool_result (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 829 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: 9, about 829 tokens to load them all
- tool set hash: 30cfb0c2a245da50d6c09ebb2ce1d110
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.getcyphrex/cyphrex-mcp.svg)](https://protogrid.dev/servers/io.github.getcyphrex/cyphrex-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (9)

- `check_action`: Run Cyphrex check on a proposed action
- `get_audit_log`: Get Cyphrex audit log for an agent
- `log_action`: Log an executed action for a Cyphrex agent
