## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `report_server`

- The description's first verb is "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit an agent usage report for an MCP server. Reports are aggregated and influence registry trust scores. Call this after using an MCP server so the registry can track real-world reliability. Supports both a simple outcome report and a structured scoring report (criterion + component_score).
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_server`

- The name "get_server" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get full details for a specific MCP server. Pass the server name (e.g. "GitHub", "Brave Search"), registry ID slug, or endpoint URL. Returns score, state, tools list, latency, and recent test history.
```

### `query_registry`

- The name "query_registry" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the Arclan registry for MCP servers. By default returns only connectable servers (active, mcp_partial, auth_gated). Use status=stdio to browse local-only servers available for installation. Use status=all to query the full index. Use production_safe=true to restrict to servers with uptime > 97% and handshake success > 95%. Use read_only=true to restrict to servers with no write or exec tools. Use this before connecting to an MCP server to check its validation status and score. After using a server, call report_server to contribute reliability data.
```

### `recommend_server`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get ranked MCP server recommendations for a task. Returns servers scored by production safety, keyword relevance, registry score, latency, and freshness. Each result includes a reason code array explaining why it was ranked. Use this instead of query_registry when you want an opinionated ranked list rather than a filtered search.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `registry`:

```json

  "permissions": {
    "allow": [
      "mcp__registry__query_registry",
      "mcp__registry__get_server",
      "mcp__registry__recommend_server"
    ],
    "ask": [
      "mcp__registry__report_server"
    ],
    "deny": []
  }
