## Changes things (2)

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

### `check_mcp_trust`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check if an MCP server is safe to install: returns a trust score (0-100, grade A-F). Accepts a registry name (io.github.x/y), a GitHub repo (owner/repo), or a remote MCP URL. For remote servers it live-connects and analyzes the actual exposed tools for tool-poisoning + capabilities, and checks the backing repo (maintenance, license, security policy, auth). Call BEFORE installing or recommending any MCP server.
```

### `scan_mcp_server`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Scan and inspect an MCP server for security issues before connecting it: live tool-poisoning analysis, exposed-tool inventory + capabilities, TLS, and repo trust signals. Same engine as check_mcp_trust. Accepts a registry name, GitHub repo, or remote MCP URL.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__mcpcheck__check_mcp_trust",
      "mcp__mcpcheck__scan_mcp_server"
    ],
    "deny": []
  }
}
```
