List Docker containers on the host system

Agent View of the PolicyLayer registry record for `docker-containers`. HTML page: https://policylayer.com/tools/0xshariq-docker-mcp-server/docker-containers

## Facts

- Tool: `docker-containers`
- Server: Docker MCP Server (`0xshariq/docker-mcp-server`) — https://policylayer.com/tools/0xshariq-docker-mcp-server.md
- Homepage: https://github.com/0xshariq/docker-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "docker-containers",
    "arguments": {}
  }
}
```

## Why docker-containers is rated Low

This tool queries Docker container information with no side effects. Listing containers is a non-destructive, informational operation. While it could expose information about running services, the severity is low because it performs no actions, creates no data, and cannot be misused to cause damage. Confidence is high due to explicit 'List' language in the description.

From the tool's own definition: "Tool name 'docker-containers' and description 'List Docker containers on the host system' indicate a read-only operation that retrieves container state without modification."

## Use case

AI agents call docker-containers to retrieve information from Docker MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Docker MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "docker-containers": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
