## Facts

- Tool: `list_collections`
- Server: ProAgentStore (`https://mcp.proagentstore.online/mcp`) — https://policylayer.com/tools/io-github-proagentstore-platform.md
- Homepage: https://github.com/ProAgentStore/platform
- Risk category: Read (Low risk)
- Registry record: grade D, identity unverified
- Server auth posture: gated
- 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": "list_collections",
    "arguments": {}
  }
}
```

## Why list_collections is rated Low

This tool retrieves schema information and metadata about existing collections—purely informational with no side effects. It does not create, modify, delete, or execute operations. The low severity reflects the limited blast radius of exposing collection structure information; while schema details could inform an attack, the tool itself performs no destructive or consequential actions.

From the tool's own definition: "Tool name is 'list_collections' and description states it 'List all data collections (tables) for an agent. Shows schema and record counts.' The verbs 'list' and 'shows' indicate read-only retrieval of metadata without modification."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call list_collections to retrieve information from ProAgentStore 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 ProAgentStore:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_collections": {}
  }
}
```

## 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`
